描述
VESTAMID L-GF15 is a glass fiber reinforced, heat-stabilized polyamide 12 (PA12) compound from Evonik Operations GmbH. The material contains approximately 15% glass fibers, an ageing protective agent, and a processing aid for fast and even mold filling.
Due to the reinforcement, moldings from this compound exhibit higher strength and good heat resistance, making it excellent for gear housings for electric window openers in cars. VESTAMID L-GF15 is specifically designed for the injection molding of rigid and tough parts.
Further advantages include the characteristic properties of PA12, such as low water absorption, good dimensional stability, and nearly constant mechanical properties at changing ambient humidity. The material is electrically isolating and fuel resistant, with good chemical resistance and dimensional stability.
VESTAMID L-GF15 is supplied as cylindrical granules, ready for processing, in moisture-proof bags. The use of colorants may change property values. 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.
