Material Notes:
Product description: Grivory GM-4H natural is a 40 % mineral reinforced engineering thermoplastic material based on a combination of semi-crystalline Polyamide with partially aromatic copolyamide. Grivory GM-4H is used for injection molding technical parts, exhibiting exceptional characteristics even after moisture absorption: high stiffness and strengthdimensional stability, low warpagegood chemical resistancegood surface finish The properties of Grivory GM-4H are almost isotropic and its strength is outstanding compared to other mineral filled materials. Metal plating (electro plating) is also possible. Grivory GM-4H is suitable for production of technical parts in the application fields of: Electro / ElectronicsAutomotiveSafety technologyMechanical engineeringDomestic appliancesInformation provided by EMS Grivory
