Chemical Auxiliary Agent Classification Bulk Polymerization SMA Resin CAS No. 31959-78-1

Howin TM SMA-700 Functional resin

Product Description

Howin TM SMA-700 is a random copolymer of styrene and maleic anhydride, produced by bulk polymerization process. Its appearance is yellowish transparent particles.

Application

Howin TM SMA-700 includes a mass of maleic anhydride group, which can be applied to:

① As heat resistant modifier for styrene resin, such as PS, AS, ABS and ASA;

② As alloy compatibilizer for styrene resin and polyester (PC, PET), polyamide alloy (PA6, PA66) and PPO alloy;

③ As coupling agent for styrene resin, PPO and glass fiber (AS/GF, ABS/GF);

④ Improve the adhesiveness of styrene resin and metal;

⑤ Improve the electroplating and stainability of styrene resin;

⑥ As chain extender for polyester (PC, PBT, PET) and polyamide .

Characteristics

Application Example

①As coupling agent, SMA-700 improves the mechanical property of ABS/GF clearly.
