Styrene Maleic Anhydride Copolymer CAS 31959-78-1 EINECS No. 231-545-4

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.

                                              Figure 1, Howin TM SMA-700's influence on mechanical property of ABS+30% GF

② As heat resistant modifier of ABS, Howin TM SMA-700 improve the HDT of ABS clearly.

                                                     Figure 2, Howin TM SMA-700's influence on the heat resistance of ABS

                                                   Figure 3, Howin TM SMA-700's influence on impact strength of ABS

Note: In figure2 and 3, ABS-1: ABS/SMA-700=50/50,ABS-2: ABS/SMA-700/high rubber content ABS

It's mainly used in modified styrene resin and alloy, such as glass fiber reinforced ABS, glass fiber reinforced AS, PC/ABS alloy, PA/ABS alloy, heat resistant ABS and so on, these materials are widely used in automobiles, household appliances and other fields, such as car rear view mirror housing, center stack, rice cooker shell, air conditioner housings etc.
