描述
VESTAMID L-R2-GF25 BK is a glass fiber reinforced, electrically conductive polyamide 12 (PA12) compound from Evonik Operations GmbH, supplied in black color. The material contains approximately 25% chopped glass fibers, a heat stabilizer, and a UV stabilizer.
This grade is specifically designed for injection molding and is especially suitable for molded parts for explosion-protected equipment and systems. The permanent antistatic and electrically conductive properties make it ideal for use in areas prone to explosions, such as coal mining and other industries.
The material combines the characteristic properties of PA12 with permanent electrical conductivity. Components made from VESTAMID L-R2-GF25 BK absorb only small amounts of water and therefore show excellent dimensional stability under changing ambient humidity. The material also features good chemical resistance, fatigue resistance, and vibration/sound damping.
VESTAMID L-R2-GF25 BK is supplied as cylindrical granules, ready for processing, in moisture-proof polyethylene containers. 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.
