Blowing Film Machine Screw and Barrel
Dong Guan KE YU New Material Technology CO.,Ltd made Polyolefin heat-shrinkable tube is an insulating sleeve with high temperature shrinkage, soft flame retardant, insulation and corrosion resistance. The heat-shrinkable tube is composed of radiation multi-linked polymer. It shrinks tightly after wrapping the cable joint , So as to achieve the purpose of insulation, sealing and protection. Widely used in the waterproofing of electronic equipment wiring, the sealing and fixing of wire branches, the corrosion protection of metal pipelines, and the prevention of loosening and shedding caused by the relaxation of polymer chains, such as underwater lighting, automobile fuel pipes, high-level wiring harnesses, etc. Initial shrinkage temperature: 70 ℃ -200 ℃; minimum complete shrinkage temperature: 105 ~ 360 ℃, standard colors are red, yellow, blue, green, black, transparent, white, brown, gray (other colors can be customized).
Different heat shrinkable tube materials can be divided into: polyolefin heat shrinkable tube, PE heat shrinkable tube, EVA heat shrinkable tube, PVC heat shrinkable tube, PET heat shrinkable tube, PVDF Heat Shrinkable Tube, KYNAR HEAT SHRINKABLE TUBE, FEP heat shrinkable tube , PTFE heat-shrinkable tube, silicone heat-shrinkable tube, fluorine rubber heat-shrinkable tube, heat-shrinkable terminal, joint heat-shrinkable tube, solder ring heat-shrinkable tube, PA rubber heat-shrinkable tube, heat-shrinkable cap.
