PBT brush bristle for vacuum cleaner brush 

PBT Brush Bristle for Vacuum Brush  A cleaning process consists of continuously rubbing between two surfaces and the friction created between both will generate heat. Both friction and heat do damage and deteriorate filaments over an extended period of use. Heat and abrasion resistant are generally affected by many outside factors other than filament properties themselves, including the surface, its rubbing against, speed and even chemical factors. Nylon Filament PA612 has heat resistance rate up to 200 centigrade and strong abrasion resistance. Through Tai Hing's unique filament enhancement process, Nylon Fiber PA612 also show better resistance against PH and great resilience.
