Automotive Injection Molding Materials
PP
PP is a lightweight, chemical-resistant material well suited for automotive injection molding. It gets into bumpers, interior trim, and storage compartments due to its economy and durability. PP’s flexibility and fatigue resistance make it good for repeated-stress uses such as clips, hinges, and fluid containers. Its chemical and moisture resistance ensure reliable performance in under-the-hood uses.
- Mill Lead Time: 5-7 days
- Color: Natural, black, gray, and custom colors available
PE
PE is valued in automotive injection molding for its resistance to chemicals and low cost. PE is utilized regularly in fuel tanks, fluid reservoirs, and under-hood components where oil and chemical resistance are necessary. PE’s light weight contributes to improved fuel economy, and its strength ensures long-term performance in extreme conditions. Its moldability leads it to suit large and complex parts.
- Mill Lead Time: 5-7 days
- Color: Natural, black, and custom colors available
ABS
ABS (Acrylonitrile Butadiene Styrene) is a common emulsion-made thermoplastic polymer that is widely used in automotive parts, toys, and electronic enclosures due to its good resistance to corrosive chemicals.
ABS is easy to machine and possesses a relatively lower melting point, which is easy to mold and form. It possesses high impact resistance that makes it ideal for applications exposed to extreme stress or pressure. Because of such unique characteristics, ABS has emerged as a popular material among various industries around the world.
Common applications: Enclosures
PC
PC is noted for its high impact strength and transparency and hence is used in automotive lighting components like headlight covers and instrument panels. Its strength and thermal resistance also make it suitable for exterior components exposed to harsh weather. PC’s maintenance of integrity and transparency under stress makes it safe to operate in safety-critical applications.
