ALTECH® PP-B A 4920/578 MR20

1 of 305 products in this brand
MOCOM Compounds ALTECH® PP-B A 4920/578 MR20 is a polypropylene copolymer pre-dried in either a dry air (dessiccant) dryer at 80-120°C for 2-3 hours, or in an air circulating dryer at 80-120°C for 2-4 hours. It is processed with injection molding at a melt temperature of 200-240°C and a mold temperature of 20-70°C. The polypropylene copolymer contains 20% talcum, has processing stabilizers, long-term heat stabilization, slip agent, and easy release (demolding) properties. It is mainly used in the automotive, building and construction, and various markets, typically for transport systems, interior, and various injection molded parts such as dashboard/instrument panels and housings.
