PTFE/FEP Encapsulation
When the most robust protection from environmental exposure is required, employ dual wall heat shrink to secure sensitive components and electrical junctions. Heat shrinkable tubing provides a tight, moisture-resistant bond over wires, cables, connectors, sensors, terminals and splices to protect them from extreme environmental conditions, including heat, corrosion, shock and moisture.
Tef Cap manufactures high-performance heat shrinkable tubing using various fluoropolymer resins. Our Dual-Wall Heat Shrink tubing is designed with the end user in mind, as we ensure secure and consistent tolerances on shrinkage to facilitate automated assembly processes.
Dual-Wall Heat Shrink from tef Cap tubing has an outer layer of PTFE and an inner layer of FEP that offers a maximum longitudinal variation of +0%/-15% after application. When heated, the inner FEP layer melts and encapsulates the junction to eliminate voids and air channels to withstand extreme environmental conditions. The high service temperature outer PTFE layer compresses the molten FEP, creating a liquid and vapor-tight seal.
Available in a variety of sizes, dimensions, and shrink ratios, our high-performance fluoropolymer heat shrinkable tubing can be customized to meet your unique needs to ensure maximum protection, reliability and performance.
