1. Regular Rubber Coating Types

When choosing rubber， you need to consider the chemical resistance, wearing resistance, and antistatic properties. Different equipment has different requirements for rubber, such as printing equipment care more about ink reaction.

 

There are various rubber types that you can choose, such as EPDM (Ethylene-Propylene-Diene Monomer); PU (Polyurethane); Silicone Rubber; NBR (Buna Nitrile); SBR (Styrene-Butadiene Rubber latex); CR (Neoprene), etc.

Technical Specifications 

 

 

Dimensions	Length: max12,000mm Diameter: max1,600mm
Dynamic balance	Specific dynamic balance requirements are related to the working speed of equipment
Runout	Runout is one of the standards to evaluate the geometrical tolerance such as roller cylindricity. Usually, the finished product's runout is between 0.02mm to 0.05mm.
Surface roughness	Turning: within Ra1.6μmFine grinding: up to Ra 0.8μm;
Size tolerance	The precision requirements depend on the process requirements
Coating thickness	Usually between 7-8mm
