Frequently Asked Questions
What is the best rubber for outdoor use?
EPDM is the best rubber for outdoor applications. It offers excellent resistance to UV radiation, ozone, and general weathering—the main factors that degrade rubber outdoors. EPDM maintains its flexibility across a wide temperature range from -40°C to +120°C and can last 15-20 years outdoors without significant degradation. This makes it ideal for building seals, automotive weatherstrips, and any application with sun exposure.
Which rubber resists oil and fuel?
Nitrile (NBR) rubber provides the best resistance to oil, fuel, and petroleum-based products. Use nitrile for automotive fuel system seals, hydraulic equipment, machinery exposed to lubricating oils, and any application involving petroleum contact. For applications requiring moderate oil resistance with better weather properties, neoprene offers a good compromise.
What rubber is food safe?
Silicone rubber is the most common food-safe option, with grades available that meet FDA and EU food contact regulations. Silicone also handles high temperatures for oven and cooking applications. For lower-temperature food applications, food-grade (white) EPDM is available at lower cost. Always verify specific product certifications match your requirements.
Which rubber is best for high temperatures?
Silicone rubber handles the highest continuous temperatures, withstanding up to 200°C continuously and brief exposure to 250°C. For more economical high-temperature applications, EPDM works well up to 120°C continuous. Avoid using natural rubber and standard neoprene above 80°C as they will degrade rapidly.
