瘦鬃毛刷

Hollow tapered filament: 1.Dia:0.18-0.22mm 2.Melting point:216-220 3.Color: hundres of colors can be choosen 4.Length:18-30+/-0.5mm(28-29mm for general used) 5.Binding diameter: 48-52mm 6.Type:doubel tapered bristle 7.Package: 10kgs/ctn 8.Character and applications: PBT has a high crystallinity which determines much of its properties. PBT has low polarity and thus low water absorption. PBT is degraded by prolonged exposure to hot water or steam via chemical reaction. PBT's high crystallinity gives it excellent chemical resistance to most organic solvents. At low temperatures (less than 130°F), PBT has excellent wear resistance. Its electrical properties are stable under varying conditions. PBT takes fillers and additives well, and it can be dyed. Properties of PBT include the following: *good physical properties*excellent wear resistance*excellent chemical resistance*high heat resistance (reinforced grades only)*opaque
