ASA (English name: acrylic acrylate copolymer), an engineering plastic, is a graft copolymer of acrylate rubber, acrylonitrile and styrene. The molding temperature is 170-230℃.
Structure: the specific gravity is1.05g/cm3; 0.4-0.7% in molding shrinkage; The molding temperature is170-230℃; The drying condition is 80-90℃ for 2 hours.
ASA resin is mainly produced by blending technology. The main raw materials are ASA powder and AS resin, pigments, antioxidants, internal and external lubricants, etc.
The main equipment is twin-screw extruder, and other supporting equipment includes high-speed dosing machine, automatic weighing feeder, cooling granulator, automatic packaging machine, quality inspection equipment (grease melting instrument, universal experimental machine, etc.). ). When the production reaches a certain scale, the finished product warehouse is needed.
Styrene:
Styrene is an organic compound with chemical formula C8H8, which is an important monomer of synthetic resin, ion exchange resin and synthetic rubber.
