描述
VESTAMID L-GF50 BK 9.7506 is a medium-viscosity, heat-stabilized, 50% glass fiber reinforced polyamide 12 (PA12) compound from Evonik Operations GmbH, supplied in black color.
Due to its excellent mold release properties, VESTAMID L-GF50 BK 9.7506 is suitable for the efficient production of injection molded parts with short cycle times. The high glass fiber content of 50% provides exceptional strength and rigidity, with a tensile modulus of 12,000 MPa and a yield stress of 150 MPa.
Further advantages include the characteristic properties of PA12: low water absorption (0.83% at saturation), good dimensional stability, and nearly constant properties at changing ambient humidity. The material also exhibits outstanding heat resistance, with a heat deflection temperature of 179°C at 0.45 MPa.
VESTAMID L-GF50 BK 9.7506 is supplied as cylindrical granules, ready for processing, in moisture-proof bags. Inside the original and undamaged packaging, the product has a shelf life of at least 2 years when stored in dry rooms at temperatures not exceeding 30°C.
