PP+30GF - Polypropylene With 30% Glass Fiber Sample

Polypropylene filled with 30% glass fiber is a reinforced thermoplastic known for its enhanced mechanical strength, stiffness, and dimensional stability. By incorporating glass fibers into standard polypropylene, the material becomes significantly more rigid and resistant to impact, heat, and warping. This makes it ideal for demanding applications in automotive components, electrical housings, appliance parts, and industrial equipment.

Despite the added strength, the material remains lightweight, which is a key advantage in industries focused on reducing overall product weight without compromising performance. The glass fiber also improves the material’s resistance to thermal expansion and increases its load-bearing capacity.

This composite material maintains many of polypropylene’s core benefits, such as chemical resistance and low moisture absorption, while overcoming some of its limitations, like low heat resistance and poor structural strength. It can be injection molded and is often used when a balance between cost, strength, and weight is needed in engineering applications.
