Nitrile Butadiene Rubber
The workhorse for oil and fuel sealing — good strength and abrasion resistance at a sensible cost.
−30 °C to +100 °C
Ethylene Propylene Diene Monomer
Outstanding weather, ozone, water and steam resistance — the first choice for outdoor and water systems.
−45 °C to +130 °C (up to +150 °C peroxide-cured)
Silicone Rubber (VMQ)
Widest temperature range of the common rubbers — and available in food-grade (FDA) formulations.
−55 °C to +200 °C
Fluorosilicone Rubber (FVMQ)
Silicone’s temperature range with added resistance to fuels and oils — widely used in aerospace.
−55 °C to +175 °C
Fluoroelastomer (commonly known as Viton®)
Premium resistance to heat, fuels, oils and aggressive chemicals where other rubbers fail.
−20 °C to +200 °C (short term +230 °C)
Polychloroprene (CR)
A balanced all-rounder: moderate oil resistance plus good weathering and flame resistance.
−35 °C to +100 °C
Natural Rubber (NR)
Unmatched resilience, tear strength and fatigue life — ideal for vibration and shock control.
−50 °C to +80 °C
Styrene Butadiene Rubber
An economical general-purpose rubber with good abrasion resistance.
−40 °C to +100 °C
Hydrogenated Nitrile Rubber
Nitrile's upgrade: higher heat and ozone resistance with excellent mechanical strength.
−30 °C to +150 °C
Polyurethane (AU / EU)
Exceptional toughness — outstanding abrasion, tear and extrusion resistance under high load.
−30 °C to +80 °C
