Wholesale Price Heavy Duty Caster Wheel White Nylon Tread With Yellow PP core Caster Load 550KGS

The strength of polyamide fiber is 1-2 times higher than that of cotton, 4-5 times higher than that of wool, and 3 times higher than that of viscose fiber. However, the heat resistance and light resistance of polyamide fiber are poor, and the retention is also poor. The clothes made of polyamide fiber are not as neat as those made of polyester fiber. In addition, the nylon - 66 and nylon - 6 used for clothing have the disadvantages of poor moisture absorption and dyeing. Therefore, a new variety of polyamide fiber, the new polyamide fiber of nylon - 3 and nylon - 4, has been developed. It has the characteristics of light weight, excellent wrinkle resistance, good air permeability, good durability, dyeing and heat setting, etc., so it is considered to be very promising. This kind of product is widely used. It is a good material to replace steel, iron, copper and other metals with plastics. It is an important engineering plastic; Cast nylon is widely used to replace the wear-resistant parts of mechanical equipment and copper and alloy as wear-resistant parts of equipment. It is suitable for making wear-resistant parts, transmission structure parts, household electrical appliance parts, automobile manufacturing parts, screw rod prevention mechanical parts, chemical machinery parts and chemical equipment. Such as turbine, gear, bearing, impeller, crank, instrument panel, drive shaft, valve, blade, screw rod, high-pressure washer, screw, nut, seal ring, shuttle, sleeve, shaft sleeve connector, etc.

Product Description

Advantage: 1. High mechanical strength, good toughness, high tensile and compressive strength. The specific tensile strength is higher than that of metal, and the specific compressive strength is comparable to that of metal, but its rigidity is less than that of metal. The tensile strength is close to the yield strength, more than twice as high as ABS. The absorption capacity of impact and stress vibration is strong, and the impact strength is much higher than that of ordinary plastics, and better than that of acetal resin. 2. The fatigue resistance is outstanding, and the parts can still maintain the original mechanical strength after repeated bending. PA is often used in situations where the periodic fatigue effect of common escalator handrails and new plastic bicycle rims is extremely obvious. 3. High softening point and heat resistance (such as nylon 46, high crystalline nylon has a high thermal deformation temperature, which can be used for a long time under 150 ℃. After glass fiber reinforcement, PA66 has a thermal deformation temperature of more than 250 ℃). 4. Smooth surface, small friction coefficient, wear-resistant. It is self-lubricating and has low noise when it is used as a movable mechanical component. It can be used without lubricant when the friction effect is not too high; If lubricant is really needed to reduce friction or help heat dissipation, water, oil, grease, etc. can be selected. Therefore, as a transmission component, it has a long service life. 5. It is resistant to corrosion, alkali and most salt liquids, weak acid, engine oil, gasoline, aromatic hydrocarbon compounds and general solvents, inert to aromatic compounds, but not resistant to strong acids and oxidants. It can resist the erosion of gasoline, oil, fat, alcohol, weak alkali, etc. and has good anti-aging ability. It can be used as packing material for lubricating oil, fuel, etc. Disadvantages: 1. Poor water absorption and dimensional stability. 2. Poor resistance to low temperature. 3. The antistatic property is poor. 4. Poor heat resistance.
