APT - Model PTFE-FEP -Dual Wall Heat Shrink Tubes for Cable Connections

APT Advanced Polymer Tubing GmbH provides technically advanced dual-wall heat shrink tubes utilizing a synergistic combination of materials: an outer Polytetrafluoroethylene (PTFE) layer and an inner Fluorinated Ethylene Propylene (FEP) layer. These tubes shrink at temperatures around 330°C and transform the FEP layer to a semifluid state, achieving a dense, enduring coating upon cooling. Technically, the integration of these materials results in a robust structure that withstands extreme temperatures from -200°C to 210°C. The tubes are proficient in forming waterproof and chemically resistant seals, suitable for aerial and moisture-proof cable connections, especially in challenging environments. With their NSF-certified fluoropolymer tubing solutions and the Teflon™ Diamond quality seal, APT aligns their products with high standards of quality and rigorous industry requirements.
