Compression Molding PTFE Fluoropolymer

Polytetrafluoroethylene Molding

Through automatic compression molding of polytetrafluoroethylene (PTFE) components, we can offer a more economical production alternative. Our compression molding process eliminates wasted material by molding parts to their finished dimensions as material cost savings can be especially important when high volume production is required. Compression molding to finished dimensions also saves labor costs by excluding unnecessary secondary machining operations. In addition, our compression molding methods allow us to achieve the optimum physical properties of components which are important in many critical applications.

DHPP compression molds virgin polytetrafluoroethylene PTFE and a wide range of various filled (modified) PTFE blends to achieve the desired mechanical, electrical and chemical properties needed for particular applications:

Virgin PTFE imparts unique characteristics focused on chemical inertness, dielectric strength and coefficient of friction.

Blended PTFE is commonly used to modify certain material properties such as compressive strength, cold flow (deformation), high-temp strength, expansion/ contraction and abrasion resistance to name a few. Listed below are just a few possible fillers most commonly blended with PTFE resin in Automatic Compression Molding: (see Materials for more details)
