The Different Types of Rubber Explained

26 March 2021

Rubber is an amazingly adaptable, universally handy material that is utilised across a gigantic scope of homegrown and mechanical applications. From the common rubber got from rubber trees through to a broad cluster of synthetic rubbers, there truly is a rubber material for each event.

1. Natural Rubber (NR)

Natural rubber (Isoprene) is gotten from the latex sap of the Pará rubber tree. Common rubber has high rigidity and is impervious to weakness from wear, like chipping, cutting or tearing.

2. Styrene-butadiene rubber (SBR)

Styrene-butadiene rubber is a minimal effort synthetic rubber that offers great scraped spot obstruction, remarkable effect strength, great versatility and high rigidity. Notwithstanding, SBR offers helpless protection from daylight, ozone, steam and oils. The fundamental uses of styrene-butadiene rubber incorporate tires and tire items, auto parts and mechanical rubber products.

3. Butyl (IIR)

Butyl rubber is an incredible choice for stun assimilation. It offers incredibly low gas and dampness porousness and remarkable protection from heat, maturing, weather, ozone, synthetic assault, flexing, scraped area and tearing. Butyl is impervious to phosphate ester-based pressure-driven liquids and has phenomenal electrical protection properties.

4. Nitrile (NBR)

Nitrile (otherwise called NBR rubber and Buna-N) is the seal business’ most broadly utilised and affordable elastomer. This is halfway because it shows magnificent protection from oil-based oils, fills, water, alcohols, silicone oils and pressure-driven liquids.

5. Neoprene® (CR)

Neoprene®, which is delegated a broadly useful elastomer, is strange in that it is respectably impervious to oil oils and weather (ozone, UV, oxygen). It is therefore remarkably qualified for certain fixing applications where numerous other materials would come up short.

6. Ethylene Propylene Diene Monomer (EPDM)

EPDM rubber is an adaptable rubber offering fantastic warmth, ozone, weathering and maturing obstruction, just as low electrical conductivity, low-pressure set and low-temperature properties. EPDM can be utilised as a savvy option in contrast to silicone and, when introduced in the right climate, can keep going quite a while before embrittling.

7. Silicone (Q)

Silicone performs well with water, steam or petrol liquids. Although it can work inside a temperature scope of – 84 to +232 degrees Celsius, silicone has been appeared to withstand short openings to lows of – 115 degrees Celsius. Silicone displays helpless tear obstruction, scraped spot and elasticity, improving its fit to static, rather than dynamic applications.

8. Viton® (FKM)

Viton® is a fluoroelastomer material fit for taking care of a different exhibit of uses. A brand name of DuPont, this sturdy synthetic rubber and fluoropolymer elastomer offers outstanding temperature solidness going from – 20 degrees Celsius to +205 degrees Celsius.

9. Polyurethane (AU)

Polyurethane is all around respected for its overall general strength, just as for its outstanding scraped spot and expulsion obstruction. O-rings produced using polyurethane material would not be reasonable for applications requiring great pressure and warmth obstruction.

10. Hydrogenated Nitrile (HNBR)

Hydrogenated nitrile rubber mixtures show preferable oil and substance obstruction over nitrile rubbers and can withstand a lot higher temperatures. HNBR guarantees magnificent protection from oils, powers, numerous synthetics, steam and ozone. It likewise offers excellent ductile and tears strength, stretching and scraped area opposition.
