DDW Type Heat Shrink (Polyolefin - Adhesive Lined)
Shrink Ratio 3:1
|
- Highly flexible, flame-retarded Polyolefin
- Inner adhesive layer melts and flows to encpsulate connectors or splices within to give water-proof seal
- Manufactured to MIL-1-23053/4
- Shrink ratio 3:1
- Suitable for enviromental protection of electrical components and particularly useful in wire harness
