ABOUT ROLLER

Material
Rubber
NR is one kind of high-fliexible rubber which can be fast- restored after recieving the power, better-resist to rip apart, and rather contrastly poor heat resistant.
IIR rubber has very good air tightness. The rubber has good elasticity and resilience. It is especially suitable for some fields that require high air tightness, heat resistance and low temperature performance. It has the disadvantage of poor processability.
It has excellent resistance to polar solvents and has good heat resistance and ink resistance. Therefore, it is widely used as rollers for cloth surface treatment and printing, or industrial rollers with general heat resistance and chemical resistance. Disadvantages: The taste is poor.
Synthetic rubber with high wear resistance, cold resistance, tensile strength and durability, good processability and low price. It is usually used for rollers that do not require heat resistance and oil resistance but want low price.
Rubber NBR is a synthetic rubber with relatively comprehensive properties. It is mainly oil-resistant, wear-resistant and aging-resistant, and has a wide range of applications. It is especially suitable for some fields that require high oil resistance and sealing properties.
VITON has excellent high temperature resistance and excellent chemical resistance. It can resist the erosion of various acids, alkalis, solvents and other corrosive media. It can maintain stable performance under high-speed friction and heavy load conditions. The disadvantage is that it is relatively expensive.
It is a synthetic rubber with excellent properties such as oil resistance, acid and alkali resistance, oxidation resistance, wear resistance, heat resistance and UV resistance.
Silicone
Silicone has excellent properties such as high temperature resistance, low temperature resistance, weather resistance, chemical resistance, etc., so it is widely used in various high-demand rollers. Due to its adhesive properties, PE extrusion laminating rollers, PVC tape embossing wheels and tape guides Rollers are widely used.
Other material
It is the abbreviation of polyurethane material. It has excellent wear resistance, can be used for a long time under high-speed movement and heavy load conditions, has excellent elasticity and tear resistance, and has the disadvantage of poor weather resistance and easy hydrolysis.
Foam materials generally have certain water resistance and corrosion resistance, and can be used in humid and corrosive environments for a long time. Foam can effectively absorb and disperse the energy of impact and vibration.
