1. Regular Rubber Coating Types

When choosing rubber， you need to consider 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: max12,000mmDiameter: max1,600mm
Dynamicbalance	Specific dynamic balancerequirements are related to the working speed of equipment
Runout	Runout is one of the standards toevaluate the geometrical tolerance such as roller cylindricity. Usually, the finished product's runout is between 0.02mm to 0.05mm.
Surfaceroughness	Turning: within Ra1.6μmFine grinding: up to Ra 0.8μm;
Sizetolerance	The precision requirements dependon the process requirements
Coatingthickness	Usually between 7-8mm
