Universal Chemical Resistance

PTFE

Polytetrafluoroethylene — The Universal Sealing Material

Temperature Range: −200°C to +260°C

PTFE (polytetrafluoroethylene) is often called the universal sealing material because it resists virtually every known chemical, operates across the widest temperature range of any elastomer-related material, and has the lowest coefficient of friction of any solid. It is essential in chemical, food, medical, and ultra-high-purity applications.

Is PTFE suitable for dynamic sealing applications?+
Yes. PTFE's extremely low friction coefficient makes it ideal for dynamic seals, slide bearings, and guides. Virgin PTFE is used for static applications, while glass-filled or carbon-filled grades are recommended for dynamic wear environments.

Ask Our Experts
Which material is best for hydraulic oil?+
NBR (Nitrile Rubber) is the most common choice for hydraulic oil applications due to its excellent oil resistance and cost-effectiveness. For higher temperatures or more demanding conditions, Viton (FKM) is the preferred upgrade. PTFE is used when chemical compatibility across multiple fluid types is required.
What is the difference between NBR and Viton?+
NBR handles petroleum oils and fuels well at moderate temperatures (up to 120°C) at a lower cost. Viton operates at much higher temperatures (up to 250°C), resists a far wider range of aggressive chemicals, and offers superior long-term sealing performance, making it the premium choice for demanding environments.
Is Silicone food-grade safe?+
Yes. Food-grade silicone is non-toxic, odourless, tasteless, and meets FDA and European food contact standards. It is widely used in food processing, dairy, beverage, and pharmaceutical equipment where direct product contact is required.
Can PTFE handle all chemicals?+
PTFE resists virtually all known chemicals, including strong acids, bases, solvents, and oxidisers. The only exceptions are molten alkali metals, elemental fluorine at high temperatures, and certain perfluorinated compounds. PTFE is the broadest-spectrum chemical-resistant sealing material available.
Which material is best for outdoor applications?+
EPDM is the first choice for outdoor applications because of its excellent resistance to UV, ozone, and weathering. Neoprene is also a good option for general outdoor and marine environments, especially when moderate oil resistance is also needed.
How do I choose the correct material for my application?+
The key factors are: operating temperature range, type of fluids or chemicals in contact, pressure conditions, dynamic or static application, food/medical compliance requirements, and environment (outdoor, UV, steam, water). Our technical team can guide you through selection based on these parameters — simply contact us with your application details.
