描述
VESTAMID L-GF30 BK 9.7503 is a glass fiber reinforced, heat-stabilized polyamide 12 (PA12) compound from Evonik Operations GmbH, supplied in black color. The material contains approximately 30% milled glass fibers, an ageing protective agent, and a processing aid for fast and even mold filling.
The use of specialty short glass fibers for reinforcement results in a significantly lower difference between longitudinal and transverse shrinkage compared to common glass fiber-reinforced products. This makes VESTAMID L-GF30 BK 9.7503 especially suitable for low-warpage precision parts and encapsulation applications.
Due to the reinforcement, moldings from this compound exhibit high strength and rigidity, while retaining the characteristic properties of PA12: low water absorption, good dimensional stability, and nearly constant mechanical properties at changing ambient humidity.
As a semi-crystalline material, VESTAMID L-GF30 BK 9.7503 features outstanding chemical resistance against fuels, oils, and greases. The compound is electrically isolating and laser absorbing, enabling laser welding and marking processes. It also exhibits high heat resistance, with an HDT of 170°C at 0.45 MPa.
VESTAMID L-GF30 BK 9.7503 is supplied as cylindrical granules, ready for processing, in moisture-proof bags. Pigmentation may affect 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.
