These wheels are manufactured form Ultra High Molecular Weight Poly Ethylene ( UHMW-PE) material. Self lubricating material. The wheels have very high load carrying capacity, high impact strength and high wear resistance; hence it does not crack under shock of impact load as it happens in nylon or fiber wheels. The material has got very low co-efficient of friction, hence pulling or pushing efforts required less. The material does not have effect of chemical and acids. This material is not hard like cast Iron hence these wheels does not damage the floor.
These wheels are moulded under controlled temperature and pressure in accurately formed close fitting moulds for unique strength and toughness. These are made by compression moulding process.
Wheel Hardness : (70 ± 5) shore D Scale, Max – working Temp : 100 C. Break Elongation : 450%, Density : 0.94GR/Cm 3 3 Tensile Strength : 440 Kg/Cm , Abrasion Loss : Min.3-8 mm / 100 SW Impact Strength [Notch] : No Break,
According to many shapes of the wheels, there are different series for which details are as under.
