3M Heat Shrink Tubing HDT is designed to provide reliable performance as well as excellent mechanical and environmental protection. This flame-retardant product combines the important advantage of easy handling and installation with maximum operating reliability and system protection. Heavy-duty tubing is fabricated from specially formulated cross-linked polyolefin, assuring long-term environmental protection.
FEATURES:
- Provide reliable performance as well as excellent mechanical and environmental protection.
- Easy handling and installation with maximum operating reliability and system protection.
- The tubing comes with a factory-applied sealant. This sealant is a heat-activated thermoplastic material that remains soft and flexible over long periods under adverse environmental conditions.
- During heating the sealant softens, bonds to underlying surfaces and fills small voids that might be present. When cool, the sealant forms a barrier against water, moisture, dirt and other environmental contaminants.
- The tubing is also highly chemical, abrasive and split resistant.
- Uncoated product (without sealant) is available on special order.
APPLICATIONS:
- The tubing is rated for continuous operation at -55ºC (-67ºF) to 110ºC (230ºF).
- Minimum shrink temperature is 121ºC (250ºF).
