What materials are heat shrink tubes made of and what are their characteristics?  

There are also many raw materials for the production of heat shrink tubing depending on different scenarios and applications. The heat shrink pipe materials commonly used in the market include mainly five materials: PVC polyvinyl chloride, PE polyethylene, PVDF polyfluoroethylene, rubber and PTFE. Each material has different performance characteristics and benefits, and the industries used are also different. Let's learn together with Fuxinyi Heat Shrink Pipe Manufacturer.

1. Heat-shrinkable pipes made from PVC - PVC materials are called PVC - heat-shrinkable pipes, the wall thickness of which is 0.08 - 0.15 mm. Due to its relatively cheap raw materials, it has very obvious cost advantages and is often used in the insulation and protective coatings of automobile batteries. The nominal operating temperature of PVC heat shrink tubing is typically 85°C and begins to soften when it reaches 85°C.

2.PE polyethylene material has excellent plastic and stable physical and chemical properties, so there are many heat shrink products made from PE polyethylene material. From traditional single wall heat shrink tubes, double wall heat shrink tubes, high voltage bus heat shrink tubes to thick wall PE heat shrink tubes, PE is used as the main material for production and fabrication. The rated operating temperature of PE heat shrink tubing is 125°C, which meets most ambient temperature requirements. The shrinkage rate is also the widest, from 2 to 6 times, with more than a dozen standard colors to choose from.

3.PVDF polyfluoroethylene is also known as fluoroplastic. PVdf heat shrink tubing has aging, corrosion, high temperature resistance, biological inertia and chemical resistance, and can be used for medical equipment pipeline coating and containment that requires high-precision high temperature resistant components. Motorcycle brake pipes are equipped with PVDF heat-shrinkable pipes. Depending on the degree of hardness, it can be divided into two categories: resistance 150°C and 175°C. The surface has high brightness and fire resistance.

4.Rubber heat shrink pipes are divided into silicone heat shrink pipes and fluorooctane heat shrink pipes, both of which meet the rated operating temperature requirement of 200°C. Silicon rubber heat shrink tube, commonly known as silicone heat shrink tube, very soft hand is currently one of the softest heat shrink tubes. It is often used in food and medical fields, can meet food grade standards. Fluorinated rubber heat shrink tubing is widely used in environments requiring high temperature oils and chemical solutions to protect cable pipelines from high temperature liquid corrosion.

5.PTFE Heat Shrink Tubing PTFE is currently the highest temperature heat shrink tubing in the industry with a rated operating temperature of up to 260°C. It has low adsorption, high sliding ability, high flame retardancy, corrosion resistance, and can withstand most strong acids and alkalis. The standard color of PTFE heat shrink tubing is usually translucent with slight bleaching.

Based on the above five points, PVC-PVC and PE-PVC heat shrink pipes have the advantages of low price and wide application. Thermal capacitors made of polyfluoroethylene PVDF, fluoride rubber and PTFE - PTFE meet the requirements of solution resistance and high temperature. You can choose the appropriate heat shrink tube according to the characteristics of different materials and the application environment of your own product.
