Types of Rubbers Used for Rubber Rollers

Introduction:

Different rubber compounds provide various mechanical properties and chemical resistance. The most popular rubber compounds that are used in rubber rollers are Mentioned below. 

  • Natural Rubber (NR):
  • Polyisoprene Rubber (IR):
  • Styrene – Butadiene Rubber (SBR):
  • Polyurethane Rollers (PUR):
  • Acrylonitrile Butadiene (Nitrile) Rubber (NBR):
  • Chloroprene (Neoprene) Rubber (CR): 
  • Silicone (VMQ):
  • Chloroprene (Neoprene) Rubber Rollers (CR):
  • Styrene – Butadiene Rubber Rollers (SBR):
  • Polybutadiene Rubber Rollers (BR):
  • Butyl Rubber Rollers (IIR):
  • Halogenated Butyl Rubber Rollers (CIIR, BIIR):
  • Acrylonitrile Butadiene (Nitrile) Rubber Rollers (NBR):
  • Ethylene Propylene Rubber Rollers (EPM, EPDM):
  • Fluorocarbon (Viton) Rubber Rollers (FKM):
  • Natural Rubber Rollers (NR):
  • Polyisoprene Rubber Rollers (IR):

Let us study some of them in details.

Details of Rubber Compounds used for Rubber Rollers are Listed as below:

Natural Rubber (NR):

With Charles Goodyear’s invention of vulcanization, natural rubber became the first commercially available rubber. It is made from latex gathered from plant barks mostly from Hevea trees. It mainly carry polymer chain polyisoprene.

While Comparing with the different types of Rubbers Natural Rubber is more suitable due to its excellent wear and fatigue resistance, Due to lack of oil, heat, and environmental resistance, this limits their applicability in most roller applications.

Polyisoprene Rubber (IR):

Synthetic polyIsoprene (IR) is a general-purpose chemical made by polymerizing isoprene monomers. This polymer chain is homogeneous to natural rubber. IR is chemically purer than natural rubber and has similar or better properties because it is manufactured in a controlled condition.

Styrene – Butadiene Rubber (SBR):

The first synthetically produced polymer, styrene-butadiene, is a butadiene-styrene copolymer. Emulsion (chain-growth) polymerization is commonly used to copolymerize it (E-SBR). As natural rubber became more difficult to come by during the war years, SBR was created as a general-purpose rubber. While it’s not as competitive as natural rubber for the market, SBR is preferred due to its expense, having appropriate tear, abrasion, and thermal resistance that is superior to natural rubber. 

Polyurethane Rollers (PUR):

Polyurethane rollers, often known as urethane rollers, are the most widely used rubber rollers. Polyurethane is well-known for its diverse set of physical characteristics. Different types and amounts of its compounding elements can be used to create a variety of blends.

It can have almost any attribute to suit a specific application. It may be made into hard, rugged, high-performance pieces like wheels and rollers, as well as soft, shock-absorbing portions like impact absorbing pads and cushions. There are a variety of formulas available on the market. Some are proprietary blends created by major chemical companies.

Because of its durability, high impingement resistance, shock absorption, and fatigue resistance, polyurethane rollers are a preferred choice. These characteristics are the result of chemical reactions. Polyol, diisocyanate, curatives, and additives are the four components of its polymer system.

Polyurethane rollers are extremely adaptable, and they can be utilised in practically any rubber roller application. Printing, milling, packaging, material handling, military and maritime, aerospace, and automotive maintenance and repair are all common applications for polyurethane rubber rollers.

Silicone (VMQ): 

Instead of a carbon backbone, these polymers comprise a silicon-oxygen chain with methyl, vinyl, and phenyl groups. Silicone rollers are resistant to oxygen, ozone, heat, light, and moisture, as well as having excellent release properties. Silicone rollers, on the other hand, are more expensive and have limited mechanical qualities.
