Product
The high-molecular-weight SMA series products feature high molecular weight, high maleic anhydride content, low VOCs and low odor. Meanwhile, they contain styrene segments, making them ideal for use as alloy compatibilizers, surface polarity modifiers, adhesives, heat-resistant agents, polymer coupling agents for reinforcing materials and chain extenders in styrene resin modification. They are particularly suitable for applications with stringent requirements for odor and residue control, such as automotive interior plastic components.
HOWIN®SMA-602 is a styrenic polymer which can be as a compatibilizer for polyamide and ABS alloy. Its appearance is yellowish granule.
SMA-800HOWIN®SMA-800 is a random terpolymer based on styrene, acrylonitrile and maleic anhydride, produced by polymerization process. Its appearance is yellowish granule.
SMA-725HOWIN® SMA-725 is a random copolymer of styrene and maleic anhydride, produced by polymerization process. Its appearance is colorless or yellowish granule.
SMA-700HOWIN® SMA-700 is a random copolymer of styrene and maleic anhydride, produced by polymerization process. Its appearance is colorless or yellowish granule.
