FEP heat shrink tubing with high shrinkage and biocompatibility

AccuPath®‘s FEP Heat Shrink provides a state-of-the-art method for applying tight and protective encapsulation for a multitude of components. AccuPath®‘s FEP Heat Shrink products are provided in their expanded state. Then, with a brief application of heat, they mold tightly over intricate and irregular shapes to form a completely strong covering.

AccuPath®‘s FEP Heat Shrink is available in standard sizes and can also be customized to meet specific customer requirements with superior precision. In addition, AccuPath®‘s FEP Heat Shrink jacketing extends the life of covered parts as it protects against extremes of heat, moisture, corrosion, and shock.
