Frequently Asked Questions
GF-reinforced PVC, halogen flame-retardant compounds with mineral fillers, engineering plastics with hard + aggressive fillers.
Chemical processing equipment, flame-retardant electrical enclosures, automotive parts in harsh chemicals, recycled material applications.
Dual-resistant construction: Ni-based bimetallic barrels with tungsten carbide, PM steel screw with PVD coating, optimized geometry.
Without both, the unprotected aspect fails first: corroding surfaces pit and accelerate abrasion; soft surfaces wear away protection, exposing fresh material to both degradations.
