Plastic additives development of the plasticizer
2013-08-07 by seoer8
plastic additive are plastic auxiliaries in quantity, production, consumption, the largest of a class of additives. Plasticizer production capacity to 2012 global force of
about 750 million tons / year, the global plasticizer production was 5.9 million tons / year, of which 22% in North America, the Asia-Pacific region accounted for 38%,
Europe 25%,
Other regions accounted for 15%. PVC is the largest user of the plasticizer , the plasticizer of the world 95% of the total volume in North America is also slightly
higher than the proportion of 90%. Polyolefins, styrenics, engineering plastics, polyvinyl butyral and cellulose used in small amounts of plasticizer. In the
plasticizer
Market, dominated phthalates was 69%, the following is an aliphatic, 8%, 7% epoxy, trimellitic acid esters, 4%, other 2%.
As plasticizers and very mature soft PVC market closely related, so the development of slow, but steady growth, expected to grow at an average annual rate of 2.5%
growth in 2009 has reached 6.1 million tons.
Plasticizer production trends to the large, continuous, microcomputer control development, a single set of production capacity has reached 100,000 tons / year. Many
varieties of serial production has strong ability to adapt to the market, the characteristics of large production flexibility to meet different plastic processing
products for special
Function plasticizer species needs. Since DOP better value for money, production and consumption still adjacent dominance dimethyl ester, followed by DINP (di-iso-
nonyl phthalate), DIDP (di-iso-decyl phthalate esters), in addition to direct chain alcohol esters developed very rapidly,
Phthalates is expected to become an important species. In addition phthalate plasticizer, fatty acid esters excellent cold resistance, non-toxic epoxy esters
stability, high temperature trimellitic esters, polyesters do not migrate, flame and good phosphate in
Structure in both the plasticizer certain proportion, form a rational structure of plasticizer production system.
