Page 1 of 1 Heat Shrink Tubing ETW-803/4 Environmental Protection Sleeve Data Sheet ________________________________________________________________________________ Product Description ETW-803 is a flexible heat shrinkable tubing with a co-extruded hot melt adhesive inner wall. The excellent flow properties of the adhesive ensure good environmental sealing of complex parts. As this tubing shrinks, molten adhesive flows and is forced into gaps and crevices. When the adhesive cools it forms a seal against moisture and other fluids whilst the outer wall provides mechanical protection. ETW-803 is well suited for environmental sealing of a variety of electronic, electrical and mechanical applications such as connections, joints etc. ETW-804 with a shrink ratio of 4 : 1 accommodates wide variances in diameter.
