The heat shrinkable sleeve is a special polyolefin heat shrinkable sleeve, which can also be called EVA. The outer layer is made of high-quality soft cross-linked polyolefin material and inner layer hot-melt adhesive. The outer layer material has the characteristics of insulation corrosion resistance and wear resistance. The inner layer has low melting point, waterproof sealing and high adhesion. advantage. Cold-shrink tubing generally refers to cold-shrinkable cable accessories. Cold-shrinkable cable accessories are molded by vulcanization molding in the factory using elastomer materials (commonly used with silicone rubber and ethylene-propylene rubber), and then expanded and lined with plastic spiral support. The components that make up the various cable accessories. For on-site installation, these pre-expanded parts are placed at the end or joint of the treated cable, and the plastic spiral strips (supports) supported by the inside are taken out and pressed against the cable insulation to form a cable attachment. Because it is elastic retractive force at normal temperature, rather than heat shrinkable cable accessories like heat shrinkage, it is commonly known as cold shrink cable accessories. The early cold-shrink cable terminations were only made of silicone rubber cold-shrinked parts for additional insulation, and the electric field treatment still used stress cone type or stress band wrapping.
As for which is better to use, or each has its own advantages, only the used ones have the right to speak.
