The ES2000-NO.4-B7-0-STK is a black flexible flame-retardant Heat Shrink Tubing made of adhesive-lined semi-rigid irradiated modified polyolefin and offers 4:1 shrink ratio. The tubing is specifically designed to meet automotive industry requirements for environmental sealing and electrical insulation of automotive wire splices, terminations and components. ES2000 tubing has an outer jacket of radiation-cross-linked, semi rigid polyolefin. Flame-retardant and mechanically tough, the jacket provides strain relief and abrasion protection of wire splices and mechanically sensitive components. The inner layer of the tubing is unique hot-melt adhesive, specially formulated to adhere to all major types of automotive wire insulation and to perform well at an extended temperature range. The adhesive forms an effective barrier against automotive fluids and moisture, helping to protect the harness from the effects of corrosion and water wicking.
