DescriptionULMAN T4301 is manufactured from ePTFE yarn with high tensile strength and a microporous structure that retains lubricants. It provides improved heat dissipation compared with conventional PTFE packings, making it suitable for high-speed pumps. The material offers excellent chemical resistance in both acidic and alkaline media. The yarn purity makes it appropriate for applications requiring high medium quality. Minimal shrinkage and stable volume ensure a permanently reliable seal.
ApplicationSuitable for use in pumps, mixers, valves and slide gates. Temperature range up to approx. 280 °C allows flexible use across various industrial processes. Typical industries include chemical and pharmaceutical production, refineries, food processing, and energy and process engineering.
