Double-wall pipe is soft, flame retardant, irradiated cross-linked double-wall heat-shrinkable tubing with plastic, the inner line of hot melt adhesive with good adhesive properties, the outer layer of soft, flame retardant irradiated cross-linked polyolefin, the shrinkage rate up to 3-4 times the contraction ends of the connection material can melt completely sealed, easy construction, no maintenance, the ability of harsh environments, moisture and other shocks, the role to protect the components, used in cable splice, the line cable and components sealed moisture-proof, waterproof, corrosion protection and insulation, repair the damaged cable insulation layer. 
 Soft green rubber heat-shrinkable tubing is used with high-quality, soft cross-linked polyolefin composite materials and environmental melt processed. Product has a soft, sealed, environmentally friendly (ROHS), the outer layer of self-extinguishing, it is widely used in electronic equipment is to waterproof, leak-proof gas, pipeline corrosion protection of metals, electronic cable repair, pumps and water submersible pump wiring . 
 Feature 
 * Shrinkage ratio 3:1,4:1, enabling the connector and cable insulation seals 
 * Due to the hot melt adhesive with excellent adhesion can be achieved cable connections and electronic components sealed moisture-proof, waterproof, corrosion 
 ? Good physical properties, chemical properties and electrical properties 
 * Hot melt layer of plastic, rubber and metal with good adhesion properties 
 ? Complies with European RoHS environmental directive and SONY SS00259 standard environmental requirements. 
 Contraction of the outer casing of high-quality double-wall polyolefin alloys, composite inner layer melt processed. After forming the product by the electron accelerator radiation crosslinking, formed a continuous expansion. With the outer insulation, corrosion, wear, etc., the inner with low melting point, sealing and cushioning properties of the advantages of mechanical strain. Widely used in electronic equipment is to water, gas leak, a branch of the sealing wire is fixed, the corrosion protection of metal pipes, wire and cable repair and other occasions.
