HowinTM SMA-725
Product Description
HOWINTMSMA-725 is a random copolymer of styrene and maleic anhydride, produced by bulk polymerization process. Its appearance is yellowish transparent granule.
Application
HOWINTMSMA-725 includes a mass of maleic anhydride group, which can be applied to: impact modifier of PA/POE-g-MAH or PA/EPDM-g-MAH.
Characteristics
Application Example
SMA-725 is used as impact modifier of toughened PA.
Figure 5 the effect of SMA-725 content on impact strength of PA6/POE-g-MAH
Figure 6 the effect of SMA-725 content on flowability of PA6/POE-g-MAH
In PA6+15%POE-g-MAH alloy, only 0.5% SMA-725 sharply increases impact strength of PA6. The possible reason is that the strong polarity of SMA-725 make rubber phase disperse better and rigid toughening function of SMA-725.But SMA-725 has negative effect on flowability of PA6.
Dosage
As impact modifier of toughened PA, less than 1wt% SMA-725 is suggested.
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.
