The caster is classified by material
The materials are mainly divided into thermoplastic polyurethane, polypropylene (pp), nylon (PA), thermoplastic rubber and polyvinyl chloride.
Characteristics of thermoplastic polyurethane: recyclable thermoplastic polyurethane tyre polypropylene copolymer, is both required load and pay attention to the ideal choice for ground protection, running low noise, wear resistance, impact resistance and spinning oil, mineral oil and some acid normal speed of 4 km/h.
Characteristics of polypropylene (pp) : recycled polypropylene copolymer's heart and tread, light and heavy, the operation is very easy manual effort, resistance to deformation under static load conditions, high cost performance, good anti chemical, moderate the impact resistance of normal operation speed of 4 km/h.
Nylon (PA) features: high quality nylon cardiac and tread, mechanical features light weight small resistance, flexible rotation, and is more efficient to use manual and mechanical, using humid environment equipment, prevent oil, crude oil, salt, acid, environmental protection material, the running speed of 4 km/h.
Thermoplastic rubber characteristics: excellent stretching resistance, strong resistance to the highest strength. Good performance of heat resistance than 70 ℃ low temperature environment for a long time under 60 ℃ can still maintain good flexibility, good electrical insulation, skid resistance, wear resistance, weather resistance, and general chemicals.
Characteristics of polyvinyl chloride: flame retardant so widely used in fire prevention applications, not easy to be acid and alkali corrosion more heat - resistant.Good tensile, bending, compression and impact resistance.
