Temp: -40°C to +90°C, medium wall halogen free tube
MWTM heat shrink tubes are designed for insulation on low voltage cable accessories, as well as for sealing and protection purposes on low and medium voltage cables. The heat shrinking tubes MWTM are halogen free and silicone free. Further these tubes are UV stabilized. MWTM tubes are inline coated with a hot meld adhesive.
