PTFE Gasket and Molded items
PTFE Gaskets and Moulded Items
At S.P. Engineers, we provide premium PTFE gaskets and moulded items to meet the most demanding industrial applications. PTFE, or Polytetrafluoroethylene, is a synthetic fluoropolymer renowned for its exceptional chemical resistance, hydrophobic properties, and low coefficient of friction. Commonly recognised by the trademark Teflon®, PTFE is widely used in applications requiring durability and non-reactivity.
We offer a versatile range of PTFE gaskets, including virgin PTFE, expanded PTFE, and glass- and carbon-filled PTFE moulded items. Our solutions are tailored for sealing applications across industries like chemical processing, food, pharmaceuticals, and petrochemicals.
Why Choose PTFE Gaskets from S.P. Engineers?
PTFE gaskets are engineered for superior performance under extreme conditions, offering excellent chemical resistance, thermal stability, and non-stick properties. By incorporating fillers such as carbon, glass, or specialised composites, our gaskets provide enhanced mechanical strength and reduced creep, making them suitable for high-pressure and high-temperature environments.
Our manufacturing process ensures precision and cost-effectiveness, with in-house CNC machinery enabling standard and bespoke gasket production to suit customer requirements.
