Material Notes:
Product description: Grivory GVX-7H natural is a 70% glass-fiber reinforced engineering thermoplastic material based on a combination of semi-crystalline polyamide with partially aromatic copolyamide. Grivory GVX-7H natural has an optimized flowability and is suitable for injection molding technical parts, exhibiting exceptional characteristics even after moisture absorption: high stiffness and strengthhigh dimensional stability, very low warpagegood chemical resistancevery good surface finish Grivory GVX-7H natural is the economical alternative to die-cast alloys.Information provided by EMS Grivory
