描述
VESTAMID L-GF30 BK E70285 is a glass fiber reinforced, heat-stabilized polyamide 12 (PA12) compound from Evonik Operations GmbH, supplied in black color. The material contains approximately 30% glass fibers, an ageing protective agent, and a processing aid for fast and even mold filling.
The distinguishing feature of VESTAMID L-GF30 BK E70285 is its good IR laser transparency. Despite being black in color, the compound has high transparency in a specific wavelength range of lasers, allowing it to be laser-welded by a diode-pumped or solid-state laser in the range of λ = 808–1064 nm . This makes it an excellent choice for automotive connector applications where laser welding is used to join plastic components .
Using glass fiber reinforcement, the strength and heat deflection temperature of the compound are significantly increased . Further advantages include the characteristic properties of PA12: low water absorption, good dimensional stability, and nearly constant properties at changing ambient humidity .
VESTAMID L-GF30 BK E70285 is supplied as cylindrical pellets, 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 .
