2025 Guide to Industrial Rubbers: Nitrile, Neoprene, EPDM, Silicone and Viton

Choosing the right rubber for industrial applications depends on multiple factors, including chemical exposure, temperature, pressure, abrasion, and environmental conditions. Each type of rubber has distinct physical and chemical properties, making it more or less suitable depending on the industry and specific use.

In this 2025 guide, we analyze five of the most commonly used rubbers in the industry: Nitrile (NBR), Neoprene (CR), EPDM, Silicone and Viton (FKM), in order to help you make more informed technical decisions in manufacturing, maintenance, or product engineering processes.

Nitrile Rubber (NBR)

Nitrile is a synthetic rubber widely used for its excellent resistance to oils, greases, and petroleum products. It has good sealing properties and mechanical strength, making it one of the most common elastomers for gaskets, packings, hoses, and hydraulic seals.

• Temperature range: -30 °C to 100 °C (up to 120 °C in special formulations)
• Excellent resistance to oils and fuels
• Good resistance to abrasion and wear
• Not recommended for prolonged exposure to ozone or the elements

Ideal for: automotive, hydraulic, agricultural and heavy machinery industries.

Neoprene Rubber (CR)

Neoprene is a versatile rubber with good overall chemical resistance and excellent weathering performance. It resists moderate oils, ozone, oxidation, and marine conditions. It also has natural flame-retardant properties.

• Temperature range: -35 °C to 100 °C
• Good resistance to moderate oils, salt water, and atmospheric agents
• Adequate mechanical resistance
• Slight elasticity, adaptable in seals and gaskets

Ideal for: outdoor applications, HVAC, marine, automotive, construction and electrical equipment.

EPDM Rubber

High molecular weight polyethylene

EPDM (Ethylene-Propylene-Diene-Monomer) is notable for its exceptional resistance to weathering, ozone, UV rays, and hot water or steam. It is not compatible with petroleum-based oils, but it performs very well in harsh environmental conditions.

• Temperature range: -50 °C to 130 °C
• Excellent for outdoor use, steam, and polar fluids
• Low electrical conductivity, ideal for electrical use
• Not suitable for oils and fuels

Ideal for: door and window seals, industrial roofs, steam systems, electrical insulation, and exterior gaskets.

Silicone Rubber

Silicone is a specialized rubber for extreme temperatures and applications requiring purity, thermal stability, and weather resistance. Despite having lower mechanical strength, it offers excellent performance where other materials fail due to temperature.

• Temperature range: -60 °C to 230 °C (some special formulations exceed 250 °C)
• Excellent thermal and electrical insulation
• Biocompatible and suitable for medical or food applications (FDA grade)
• Limited resistance to industrial oils and solvents

Ideal for: food, pharmaceutical, electrical, medical industries, ovens, lighting and air conditioning.

Viton rubber (FKM)

Viton is a high-performance fluorocarbon rubber used in demanding industrial environments. It offers superior resistance to high temperatures, aggressive chemicals, fuels, and solvents. While it is more expensive, its durability justifies the investment.

• Temperature range: -25 °C to 250 °C
• Excellent resistance to hydrocarbons, acids, oils, gases and solvents
• High thermal and chemical stability
• Very low permeability, ideal for critical sealing

Ideal for: refineries, chemical plants, aerospace industry, sealing corrosive processes and fuel lines.

How to choose the right rubber?

To select the correct rubber, you should consider:

• Operating temperature
• Contact with oils, fuels, acids, or other chemicals
• Exposure to the elements, ozone, or UV radiation
• Flexibility, elasticity or rigidity required
• Regulatory requirements: food grade, biocompatibility, or electrical resistance

There is no single rubber that fits all applications. That's why understanding the specific properties of each type is key to preventing premature failure, operational downtime, and loss of efficiency.
