(7) What Are The Differences Between PET And PVC Heat Shrink Tubes?
PET Heat Shrink Tubing:
Chemical Structure: PET is a thermoplastic polymer that is part of the polyester family. It is known for its strength, durability, and resistance to various chemicals.
Shrink Ratio: PET tubing typically offers a high shrink ratio, often up to 75%, which allows it to tightly conform to the shape of the object it covers. This property is particularly beneficial for applications requiring a snug fit.
Temperature Resistance: PET can withstand higher temperatures compared to PVC, with a shrink temperature starting around 60ºC (140ºF), and can operate effectively in environments up to 125ºC (257ºF).
PVC Heat Shrink Tubing:
Chemical Structure: PVC is a widely used thermoplastic that is known for its versatility and cost-effectiveness. It is less durable than PET but offers good insulation properties.
Shrink Ratio: PVC typically has a nominal shrink ratio of 2:1, meaning it can reduce its diameter to half when heated. This makes it suitable for a variety of applications, although it may not provide as tight a fit as PET.
Temperature Resistance: PVC has a lower temperature tolerance, with a maximum operating temperature of around 85ºC (185ºF). This limits its use in high-temperature environments.
