Enhancing Valve Components with PTFE and Additives

The choice between pure Polytetrafluoroethylene (PTFE) and additive-enhanced PTFE is crucial in valve manufacturing, impacting performance, durability, and compliance with industry standards. This article briefly explores the suitability of pure PTFE and its additives across various applications. 

Pure PTFE: Ideal for Purity-Critical Industries

Pure PTFE, known for its chemical resistance and minimal friction, is perfect for valve seats, diaphragms, and gaskets in industries like pharmaceuticals, food and beverage, and semiconductor manufacturing. Its use ensures that components remain uncontaminated, meeting the highest standards of purity and safety. 

Enhanced PTFE: Customised for Demanding Applications

Additives can significantly improve PTFE's properties, making it suitable for more challenging environments: 

• Glass Fibres: Enhance wear resistance and reduce creep, making glass-filled PTFE ideal for chemical processing valves.
• Carbon and Graphite: Improve thermal conductivity and friction properties, suitable for energy sector components exposed to high temperatures.
• Bronze: Increases strength, recommended for automotive and aerospace applications requiring durable pneumatic and hydraulic systems.
• Moly Sulphide: Adds to the mechanical strength and wear resistance of PTFE, perfect for applications that demand durability alongside resistance to corrosion. Stainless steel-filled PTFE is particularly beneficial in the food processing and pharmaceutical industries, where both cleanliness and material strength are paramount.
