The main analysis antimony flame retardant
flame retardant halogen-containing polymer refers to a mixture or combination of halogen-containing flame retardants made, mainly antimony trioxide and decaBDE, which is often said antimony and bromine flame retardants, bromine and antimony grade has excellent flame retardant properties, served as resistance en materials are widely used. However, when the fire occurred, such halogen-containing flame retardant material manufactured heat will produce a lot of smoke and toxic and corrosive hydrogen halide, antimony flame retardant into a secondary cause harm. Is about the Impact modifier limit and prohibit the use of certain instructions toxic and hazardous substances and elements began to implement a new classification method and flame test standard in wire and cable, building materials, paint and other industries in the electrical and electronic equipment. China also began to approval of building materials and products of combustion performance level national standards. China’s flame retardant grade and national standards and new standards of Western Europe has many of the same PVC heat stabilizer characteristics, that is: to emphasize the development rate of fire, heat release rate, smoke and combustion products of corrosive and toxic flame retardant as the judge’s standards. In order to pass this new standard, the traditional halogen flame-retardant materials, such as antimony trioxide will be powerless.
The new flame retardant system, antimony flame retardant small amount of smoke when burned, does not produce corrosive, toxic gas. Halogen-free flame retardant mainly phosphorus-based compounds and metal hydroxides.
Halogen-free flame retardant is a phosphorus-nitrogen based organic flame retardant high performance, a triazine compound and a triazine trione PVC plasticizer compound triamines, after a special surface treatment, it is easily dispersed in the plastic material, no precipitated with good flame-retardant effect.
To protect the safety of people’s lives PVC plasticizer
When it comes to plasticizers, plasticizers what we would like to, ah, heard how I said, ah, some such similar problems, in fact, we have a lot Chlorinated paraffin of life to add a plasticizer things. We want some drunk beverage plastic bottle washer, it is to add a plasticizer effect. In this have to say about our health problems. We have some kids is not only a drink, it is often in direct contact with the mouth bottle, PVC plasticizer and thus indirect contact with plastic washers, including safety hazards which exist. Although China has been developing and this demanding but Titanium dioxide rutile non-toxic plasticizer, but our research and production is still a large gap with the developed countries, which we need to work with the plasticizer manufacturers struggled. So we pay attention to a lot of these small issues, so as to endanger the health of our own unknowingly….
Plasticizer for PVC how to respond to future market challenges
Because many companies related to international trade regulations insufficient attention on the face of the endless variety of new regulations by surprise, in children’s toys, food packaging, consumer goods and medical plastic products such as foreign trade industry has been a huge hit. Despite a greater impact, but the introduction of various international trade regulations, Plasticizer for PVC is to ensure that the risk of harmful plasticizers are reasonable control and gradually replaced. Although the PVC plasticizer new international regulations to establish a high technical barriers, but once beyond, domestic enterprises from both technical and market while promoting industrial upgrading plasticizer.
China’s plastics industry is still huge room for development, but we must increase investment in technological innovation, attention to the introduction and training of technical personnel, to strengthen cooperation with universities and research institutes at home and abroad to track the latest trends in PVC flame retardant technology development, there are efforts to develop self-knowledge property rights and proprietary technology products to improve the overall technological level of industry and innovation capability.
Plasticizer for PVC to provide mankind with a high-quality plastic products indispensable role, but it brings security issues, environmental hazards, pose a new challenge to humanity. Since January 2007 the European Union plastic additive banned the use of DBP and DOP in toys and daily necessities. United States and Japan and other countries have also introduced a package of food and other consumer products and toys plasticizer statute of limitations. R & D use of safe, environmentally friendly plasticizer has become an urgent task development of the industry.
Accelerate the elimination of toxic plasticizers and promote the development of new non-toxic plasticizer has become an inevitable trend. Therefore, domestic enterprises must constantly monitor plasticizer regulations related fields exporter latest updates, progress and adjustments and changes, early good response. Second, to increase the new “non-toxic type”, environmentally friendly plasticizer research and development efforts, the right to judge the market demand, timely adjustment of the production structure.

Market participants Oxo afternoon on the sidelines , in addition, some market participants have not yet returned to the field , to discuss the white blowing agent current market apathy , turnover scarce, the market price of transient stability . DOP prices being stable, but affected by the following factors, the market sentiment is still waiting to see re : First, international oil prices rose , the mentality of the market has been boosted . Secondly , raw materials : propylene prices continued to fall caused many market participants believe that there is still some room for downward adjustment octanol , and therefore lack of confidence DOP market ; On the other hand , domestic octanol factory is still running “deferred settlement” ( part of the market -person ” insured ” ) , and its final settlement price is still unpredictable. Meanwhile, many market participants have not yet returned after the holiday farm , so DOP talk much, the price changed little.
Some of the major role of pvc plasticizer
Plasticizers (English: Plasticizer), also known as a plasticizer, the plasticizer, or a flexible material as liquefied additive increases. Add Chrolinated polyethylene object contains plastic, concrete, drywall materials, cement and gypsum and so on. A plasticizer is often used with the different objects, but the effect is often not the same. According to statistics, in 2004 the world market plasticizer total of about 5.5 million tons and 6,000,000 tons moving toward. Based on the use of plastic plasticizer added features, different environments, manufactured with a variety of toughness hardness, gloss finished the more plasticizer, pvc plasticizer which more soft plastic products required to add. General wrap commonly used one is no additive PE (polyethylene) material, but its poor stickiness; Another widely used is PVC (polyvinyl chloride) plastic wrap, a large number of plasticizers to make PVC material becomes soft and increases aluminium stearate the viscosity, ideal for fresh food packaging. Use concrete plasticizer (water reducer), the mixture can be increased to facilitate the work of construction is not easy to produce honeycomb, thereby reducing the proportion of water to increase strength. Join plasticizing agent in a mixture of wall materials can increase the degree of liquefaction, so they do not add too much water, can reduce the time required for drying the wall. The basic types of plasticizer in the plasticized polymer is actually part. The plasticizer is generally in the polymerization of the second monomer in the polymer is introduced. Since the second monomer in the molecular structure of the polymer, pvc plasticizer reduces the polymer molecular chains are isotacticity, i.e. reducing the crystallinity of the polymer chain. Such as vinyl chloride – vinyl acetate copolymer softer than vinyl chloride homopolymer. Plasticizer within a relatively narrow temperature range, and must be added to the polymerization process and therefore less use of the plasticizer. Outside the plasticizer is a low molecular weight plasticizer compound or a polymer, the need to add it in the plasticized polymer, the polymer can increase the plasticity. External plasticizer is generally less volatile liquid or low melting solids a high boiling point, and the vast majority of organic compounds are esters. Usually they are not primarily in the polymer swelling action of elevated temperature, to form a solid solution with the polymer chemical reaction and interaction between the polymer from. Outside plasticizers production and use of more comprehensive and easy to use, very wide application. Now people say plasticizers are generally refers to external plasticizer. Octyl phthalate (DOP) and dibutyl phthalate (DBP) are outside the plasticizer
History and Development pvc plasticizer detailed description
1. History back fact, plasticized technology originated in Chlorinated paraffin primitive human invention. Such as making pottery clay with water, the water is a plasticizer; gelatin or water making fudge dessert, water is also a plasticizer; skin alone I | make it soft
Soft, remaining oil is the most enduring plasticizer. In ancient times, the oil dissolved in dry Lek tone. Use waterproof “& fill the boat joints, @ that play the role of plasticizer. Most direct origins of modern plasticizer industry is the Aluminum hydroxide development of surface coatings. Using collodion plus castor oil into a non-blame-inducing roar today:?’s, famous for rubber balloon 8 coffee ⑸ use nitrocellulose varnish and linseed sleeves and mixed-mode or a high degree of waterproof coatings, as well as factors such as coal nitrate Victor Zue do tar roof coatings, etc. Among the seedlings sesame oil, linseed PVC plasticizer oil and other substances that increase the plasticity and Caine plays early role.
The main categories of pvc plasticizer
( 1 ) using the new catalyst. Currently , the majority of green plasticizer produced using conventional sulfuric acid catalyst , although its low cost, high catalytic activity , but there are serious corrosion of equipment , post-processing complex process, reaction selectivity , serious environmental pollution and other defects , and thus need to expedite find new plasticizer can replace sulfuric acid catalyst catalyst aluminium stearate research , production or under development now has a class sodium bisulfate , solid super acid , p-toluenesulfonic acid , inorganic salts , amino acids and heteropoly acids and so on. ( 2 ) the use of new synthetic processes. Now many long green plasticizer production process , equipment and more, poor waste treatment capacity, product quality, while looking for short process, less equipment , less by-products , high Polyethylene wax product quality, new synthetic process is the production of green plasticizer future an important direction .
( 3 ) reducing cost. A common feature is that the high price of green plasticizer , which largely limits their applications. Therefore, the development direction of the plasticizer is large, continuous, automated , in order to lower prices , better adapt to market demand. PVC plasticizers only follow a benign market needs in stearic acid order to survive to grow, green products is not just an empty slogan sentence in the fierce market competition, we have to pay attention and participate . In order to create a good plasticizer market environment.
pvcplasticizer what purpose and to introduce
Is the increase of plastic plasticizer plasticizer to improve flowability of the resin during molding , and to articles having a flexible organic material . It is usually some high boiling, viscous liquid or difficult volatile low melting solids , generally do not react chemically with the plastic . First plasticizer having good compatibility with the resin , compatibility is better , the better the plasticizing effect .
