Made of semi-crystalline fluoropolymer, this ball is distinguished by its lightness and exceptional corrosion resistance. This is the perfect choice for high temperature applications. Although its mechanical properties may be lower than those of other plastic materials, it offers excellent electrical isolation and has self-lubricating qualities. Note that exposure to electromagnetic radiation may affect material characteristics and that variations in colour may occur.
