Polypropylene, sometimes referred to as pp, is a synthetic resin used in our injection molding for a wide range of applications. Polypropylene is one of the lowest density plastics; the density ranges between 0.895 and 0.92 g/cm. Polyproplyene is safe for use as food containers because polypropylene does not leach chemicals into food products. Trust BRP for all your polyproplyene injection molding needs. BRP offers a variety of plastic polypropylene injection molding services to create parts and products of all shapes and sizes. Our fleet of injection molding equipment ranges from 28-ton machinery for smaller components to 1000-ton machines suitable for large parts.
Why use polypropylene for injection molding?
·Excellent moisture resistance
·Mold in or“living hinge”capabilities
·Food grade availability
·Excellent impact strength
Polypropylene (PP) is known for its flexibility in packaging, fluid management and processing, and household goods, as well as some automotive applications. While polypropylene is flammable and vulnerable to UV radiation, it still offers good resistance to chemical solvents and electricity. Most grades of Polypropylene are flammable and degraded by UV radiation.
With plastic injection molding, nylon polyamide can be cast into gears, bushings, plastic bearings, and other components for mechanical equipment like engines.
