Heat shrinkable tube is a kind of casing that can be heat-shrinked. Heat-shrinkable tubes are different according to their uses and properties, so the materials used are also different. Today, the editor of Fuxinyi heat-shrinkable tube manufacturer will start with the heat-shrinkable material. For the convenience of everyone, I would like to give you some popular science on what materials heat shrinkable tubes are made of, and what heat shrinkable tube products correspond to each material.

1. First of all, the most widely used material is PE (polyethylene), which currently has a very high market share. The main products made of PE materials include low-voltage insulating heat shrinkable tubes, yellow and green two-color heat shrinkable tubes, and anti-skid pattern heat shrinkable tubes.

2. The second is the heat shrinkable tube made of PE (polyethylene) + hot melt adhesive. The heat shrinkable tubes compounded of these two materials mainly include double-wall heat shrinkable tubes, adhesive medium-wall heat shrinkable tubes, and adhesive thick-walled tubes. Heat shrink tubing.

3. PVDF (polyvinylidene fluoride) material. Polyvinylidene fluoride material has high cutting resistance and excellent temperature resistance. The main product is very simple, which is called PVDF heat shrinkable tube. It is divided into heat shrinkable tubes according to its temperature resistance. 150℃ and 175℃, 150℃ is softer and 175℃ is semi-hard.

4. The fluororubber material is oil-resistant and high-temperature resistant. Because of the market demand for such products, there are also fluororubber heat shrinkable tubes, which can withstand temperatures of 200°C for a long time and are especially suitable for parts used in high-temperature oils. Protect.

5. PTFE Teflon (polytetrafluoroethylene), as the king of plastics, has such excellent physical and chemical properties that it is certainly not absent in the field of heat shrinkable tubes. Teflon heat shrinkable tubes can withstand temperatures of 260°C for a long time.

   Currently, the commonly used heat shrinkable tubes are mainly divided into four materials: PE (polyethylene), PVDF (polyvinylidene fluoride), fluororubber, and PTFE Teflon (polytetrafluoroethylene). They are suitable for various applications in terms of working temperature and purpose. There is always a suitable one for every industry.
