Discover advanced valve products made from PTFE, PCTFE, PEEK, and PPS—Ideal for demanding industrial applications, these polymers ensure reliability and efficiency in critical environments.

Due to its extremely low friction and high chemical compatibility across a wide range of chemical types, PTFE seats frequently rank towards the top of the list as a ball valve material. It comes in a variety of FDA-approved grades and is non-contaminating.

PTFE properties are often enhanced using a variety of fillers creating a PTFE compound, such as a 15 or 25% glass filled PTFE, to improve wear resistance, increase part stability, and improves creep strength and reduce deformation under load in comparison with virgin grade PTFE. PTFE resin does not flow when it melts and cannot be injection molded. The best method is molding and machining.

Dechengwang can provide a wide size range of PTFE tube, rod, and film&sheet. Our material type including virgin PTFE, modified PTFE and PTFE compounds material. Our in-house compounding capability allows us Unlimited explore difference PTFE Compounds grade.

PTFE bellows are used as balancing elements between engineering parts, which is widely used in chemical, food and medical appliances. The different geometres of the folds highly flexible or pressure-resistant versions can be designed and manufactured to reach higher flexibility or compressive strength. External and internal Pressure, number of runs and all -closed/ all-open lengths are the critical factors to consider in designing a bellow.
Whether your PTFE bellow requirements are simple or complex, our experts have the ability to customized Design and Performance.

Whether the project is a micro PTFE component for electronics or a large size gasket for the Oil & Gas industry, we have the know‐how and rich skills to provide stable quality and accurate service.
