Tubing with an adhesive layer, shrinkage ratio of 4:1, and medium wall thickness
Type: STTK (3:1) (TU 2247-021-97284872-2006)
- Designed for sealing, insulation, and corrosion protection of contact joints in the electric power and telecommunication industries
- Extended shrinkage ratio: 3:1 to 4:1
- Material: Polyolefin
- Color: Black
- The thickness of average STTK tubes is significantly higher than that of standard TTK tube (4:1)
- Medium-sized adhesive heat shrink tubing have exceptional mechanical strength, abrasion resistance, and insulation properties
- A layer of hot melt glue is applied to the entire inner surface of the shrink tubing by co-extrusion
- The heat shrink tubing is resistant to UV radiation and weather, environmental, and climatic factors
- During shrinkage, the adhesive layer melts down, fills all irregularities of the surface, and completely seals the joints
- Delivery package: 1 m or 1.22 m cuts
- Installation tools: TT-1800 heat gun, PG propane burners, or portable butane burners (KVT)
