Homo Polypropylene Glass Fiber Polymer Wide Applications

Which Is Better, Homopolymer or Copolymer?

It depends.

Neither homopolymer nor copolymer is better than the other. It will depend on the application as to which is more desirable. Homopolymers are better suited to high-strength and high-hardness applications, whereas copolymers are suited for corrosion resistance and high operating temperatures. Although a raw homopolymer has better mechanical properties, copolymers have better mechanical properties when reinforced with glass over glass-reinforced homopolymer. This is because copolymers are better suited to adhering to fibers. 

Comparison: 

Long Carbon Fiber vs. Short Carbon Fiber Composites

Applications
HPP (Homopolymer Polypropylene) long glass fiber reinforced materials
Automotive structural components (e.g. front-end modules, battery trays, brackets)
Load-bearing industrial parts
Technical enclosures exposed to high mechanical loads
Structural parts requiring tight dimensional tolerances
Components exposed to heat and chemicals

CPP (Copolymer Polypropylene) long glass fiber reinforced materials:
Power tool housings
Sports and outdoor equipment
Household appliances and electronic casings
Automotive interior parts that may face dynamic loads or vibration
Structural components in cold environments
