impact modifier some of the major role

Impact modifier 's primary role is to improve the low-temperature embrittlement of polymer materials , giving it a higher toughness. Global plastics market demand impact modifier is 600,000 tons ( worth about $ 1.5 billion ) , of which styrene copolymers such as ABS, methyl methacrylate - butadiene - styrene (MBS) impact modifier to become the carbon black powder  largest category, accounting for about 45% of the market share, accounting for nearly 30% acrylic ; elastomers including EPDM and thermoplastic elastomer (TPE) accounts for about 10% market share ; chlorinated polyethylene (CPE) accounted for 10 %, other 5%. It is predicted that between 2004 to 2009 , a styrene-based impact modifiers average growth rate will be less than 3% , while the other categories, the average growth rate of 5% -6%. Because PVC is the  plastic additive largest impact modifiers used species, accounting for about 80% of the amount , so the growth in demand for PVC impact modifier will also be driven by increased demand . Engineering plastic resins such as PC, polyamide (PA), polyester, impact modifiers consumption of about 10 % due to strong growth in demand for engineering plastics is to promote growth in the amount of impact modifiers . Polyolefin resin consumes approximately 10% of the impact resistance improver. Experts pointed out that the future impact modifier trend is  black iron oxide better performance, prices cheaper, faster action , the main material properties or guarantee performance under the premise of improving the member thinner.
