PP-Material Reference|Specializes in metal and plastic parts manufacturing via injection mold and CNC machining etc.

Polypropylene – PP 30% Glass Fibre Coupled

Polymer Type

Thermoplastic

Advantages

Significantly improved stiffness, strength, hardness, HDT, dimensional stability and reduced creep compared with unmodified PP. Coupled fibres yield greater stiffness and strength compared to uncoupled.

Disadvantages

Relatively expensive and significantly reduced elongation at break compared with unmodified PP.
