What is the high temperature resistance of PVDF Heat Shrinkable Tubing?
PVDF Heat Shrinkable Tubing has excellent high temperature resistance, with an operating temperature range of -55°C to 175°C, a minimum shrinkage temperature of 155°C, and a minimum full shrinkage temperature of 175°C. The temperature range of PVDF Heat Shrinkable Tubing is -55°C to 175°C, with a minimum shrinkage temperature of 155°C.
How does PVDF Heat Shrinkable Tubing shrink?
PVDF Heat Shrinkable Tubing shrinks by heat, usually using a heat gun or heat shrink machine to heat the tubing to a certain temperature, it will automatically shrink and wrap tightly around the protected object.
What is the shrinkage ratio of PVDF Heat Shrinkable Tubing?
PVDF Heat Shrinkable Tubing typically has a shrinkage ratio of 2:1, which means that when the tubing is heated and shrunk, its diameter is reduced to half of its original diameter.
What are the chemical properties of PVDF Heat Shrinkable Tubing?
PVDF Heat Shrinkable Tubing has excellent chemical resistance and is able to resist corrosion at room temperature from chemicals such as acids, alkalis, strong oxidizers and halogens.
What are the advantages of PVDF Heat Shrinkable Tubing over other heat shrink materials?
PVDF Heat Shrinkable Tubing has higher mechanical strength, abrasion resistance, weatherability and self-lubricating properties than other heat shrink materials.
What are the key steps in the production process of PVDF Heat Shrinkable Tubing?
The manufacturing process for PVDF Heat Shrinkable Tubing includes the key steps of compounding, extrusion, irradiation, expansion and packaging, with irradiation cross-linking being an important part of the manufacturing process to improve the properties of the tubing.
How flame retardant is PVDF Heat Shrinkable Tubing?
PVDF Heat Shrinkable Tubing is highly flame retardant, which reduces the risk of fire spreading in extreme situations such as fires.
What should I pay attention to when using PVDF Heat Shrinkable Tubing?
When using PVDF Heat Shrinkable Tubing, care needs to be taken with the heating temperature and heating time to ensure that the tubing shrinks sufficiently and wraps tightly around the object to be protected. At the same time, care needs to be taken to avoid overheating, which could damage the protected object or the tubing itself.
