About ePTFE
About ePTFE
Expanded polytetrafluoroethylene (ePTFE) material possesses numerous significant product advantages due to its unique physical and chemical properties.
High Sealability:
High Sealability:
The multidirectional fiber structure inside expanded polytetrafluoroethylene (ePTFE) sheets provides excellent sealing performance, enabling effective sealing even on rough or irregular surfaces.
Chemical Resistance:
Chemical Resistance:
ePTFE sheets exhibit outstanding chemical resistance, being unaffected by almost all chemicals, except for molten alkali metals and free fluorine atoms.
Temperature Resistance:
Temperature Resistance:
This material can be used within a very wide temperature range (-260°C to 280°C), enduring both low and high temperatures, making it suitable for applications under extreme conditions.
Flexibility and Elasticity:
Flexibility and Elasticity:
ePTFE sheets are highly flexible, easy to bend and fold, and also possess good resilience, meaning they can return to their original shape after being compressed.
Self-Lubricating:
Self-Lubricating:
Due to their smooth surfaces and low friction coefficients, ePTFE sheets possess self-lubricating properties, making them ideal materials for sliding components.
Free of Harmful Substances:
Free of Harmful Substances:
This material does not contain any binders or additives, therefore it does not release harmful substances, ensuring safe use.
Weather and Aging Resistance:
Weather and Aging Resistance:
ePTFE sheets exhibit excellent weatherability and aging resistance, with no performance degradation occurring even after long-term exposure to natural environments.
Easy to Process:
Easy to Process:
ePTFE sheets are soft and easy to cut, allowing them to be easily trimmed into the required shapes by mechanical or manual means, facilitating installation and use.
Easy to Clean:
Easy to Clean:
Due to their hydrophobic and oleophobic surfaces, ePTFE sheets are not prone to dirt accumulation and are easy to clean, suitable for applications with high cleanliness requirements.
