Rubber roller coating is critically important for the efficient operation of production lines in the textile, paper, food, steel and packaging sectors. The right rubber material selection directly affects the roller's lifespan, performance and total cost of ownership.
What Is Rubber Roller Coating?
Rubber roller coating is the process of applying rubber material with specific properties to the outer surface of a steel or metal-bodied cylinder. This coating enables the roller to withstand friction, wear, chemical and temperature conditions, while performing its transport and compression function without damaging the processed material (fabric, paper, metal sheet, etc.).
Rubber Types and Selection Criteria
Nitrile (NBR) Rubber
Offers excellent resistance to oil and petroleum. Ideal for printing machines and lines operating in oily environments. Temperature range is -30°C to +120°C.
EPDM Rubber
Superior resistance to water, steam, ozone and weathering. Preferred in the food sector, water treatment plants and outdoor applications. However, weak against oil and petroleum.
Silicone Rubber
Has the widest temperature range of any rubber type (-60°C to +230°C). Widely used in the food sector as it does not transfer odour or taste. Also ideal for lamination and hot press lines.
Hypalon (CSM) Rubber
Excellent resistance to weathering, ozone, acids and chemicals. Preferred in chemical and heavy industry applications. High colour stability.
Neoprene (CR) Rubber
A general-purpose rubber type with good oil resistance, moderate wear resistance and flame-retardant properties.
Ebonite
A very hard rubber type used as lining material in chemical tanks and in electrical insulation. Offers high chemical and electrical resistance.
Roller Maintenance and Extending Service Life
Key points to extend roller coating life:
Regular cleaning: Clean roller surfaces with appropriate solvents after production. Dirt and residue build-up accelerates wear.
Grinding intervals: Have professional grinding performed when roller surface smoothness deteriorates. This directly affects print and product quality.
Storage conditions: Store unused rollers in cool, dry environments protected from direct sunlight.
Re-coating: When rubber wears down, re-coating instead of purchasing new rollers is both an economical and environmentally friendly solution.
