Heat shrink tube is a special polyolefin material which can also be called EVA material. The outer layer is made of high-quality and soft cross-linked polyolefin material and the inner layer of hot melt adhesive. The outer layer has the characteristics of insulation,corrosion resistance and wear resistance and the inner layer has advantage of low melting point,waterproof sealing and high adhesion.


Cold shrink tube generally refers to the cold shrink cable accessories.The cold shrink cable accessories are injection vulcanized which use elastomer materials(silicone rubber and ethylene-propylene rubber are commonly used). Then expanded and lined with plastic supporting pieces on then end or joint of the cable after treatment.When install the site,we need to draw our the internal plastic supporting cores and press it on the cable. The cold shrink tube is easier installed than the heat shrink tube.No need heating or other tools.In summary,the cold shrink tube is better than heat shrink tube in installation way and technical performance.


The silicone cold shrink tube reliably seals electrical connections of electric communications and cable televisions against water and moisture and effectively insulates wire and cable connections or joints and other electrical connections etc.For the cold shrink tube,we have full set of technical performance test report from SGS Such as IP68 waterproof grade,UV resistant,Ozone Aging, High temperature resistant,Antimicrobial activity test report,etc.So our quality is guaranteed. Volsun was founded in 2006, as the pionner of cold shrink tube manufacturer in China for more than 14 years.We keep focusing on the R&D, production and sales in insulaiton, sealing & protection solutions.Quality is our culture.Volsun has a mondern quality manangement system,which has passed a series of quality system certification such as IATF16949, ISO9001.
