FEP Resin, short for Fluorinated Ethylene Propylene Resin, is a type of fluoroplastic made from the polymerization of TFE and HFP . It has similar properties to PTFE (polytetrafluoroethylene, commonly known as Teflon), but is easier to process and mold, and is widely used in areas requiring high temperature, corrosion resistance, and insulation.

ER202 is the go-to resin for applications requiring low- or medium-speed processing, enhanced crack resistance, and chemical durability, such as heat shrinkable tubes, pumps, and valves.
ER204 excels in high-precision, thin-walled applications, particularly in electronic insulation and medical tubing, where heat stress cracking resistance and long-term performance are critical.
