Abstract
Process for production of a long fiber glass-filled ABS comprising (a) forming a long glass fiber master-batch by adding a long glass fiber to a high flow styrene-acrylonitrile (SAN) copolymer and (U) blending the master-batch with meat mass ABS resin. A molded article demonstrating High dimensional stability, good impact, strength anal heat performance is obtained.
Claims13
A method for producing a long glass fiber-reinforced thermoplastic resin composition, the method comprising the steps of:
- selecting a quantity of long glass fiber having a length of 3.0 mm to 30 mm;
- adding the selected quantity of long glass fiber to a first styrenic copolymer to form a master-batch, said first styrenic copolymer being a high flow copolymer;
- and
- blending the master-batch with a second copolymer comprising a stiffer flowing amorphous styrenic copolymers.
