2、3 ABS COPOLYMER ESB-M4D24-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a single, uniform molecular structure consisting basically of acrylonitrile, butadiene and styrene (ABS). It is suitable for processing by calendering, extruding, injection molding and po
3、st forming. 2. APPLICATION This specification was released originally for materials suitable for use as seat track covers, center pillar covers, instrument panel sections and other interior trim applications requiring special surface colors and grains. It may also be used as air ducts on heater and
4、air conditioning installations or for similar functional applications where the surface finish and color is of secondary importance. 3.
