Made of semi-crystalline thermoplastic fluoropolymer, these balls offer remarkable resistance to corrosion, aging and UV radiation. Their lower density makes it possible to improve the mechanical characteristics while ensuring good resistance to abrasion. Although their resistance to high temperatures is lower than that of teflon, they remain highly effective in many applications. Please note that the appearance of these balls may vary from lot to lot.
