FAQ:
1) What is heat shrink tubing used for?
A: Heat shrink tubing is used for insulation, bundling, sealing, strain relief, and wire harness protection.
2) What materials are available?
A: Common materials include polyolefin, PVC, PTFE, FEP, and other specialty compounds depending on temperature and environmental requirements.
3) Which tubing is suitable for high temperatures?
A: PTFE and FEP are common choices for higher-temperature environments, while polyolefin is used more widely for general applications.
4) How do I choose the right shrink tubing?
A: Selection should be based on recovered size, shrink ratio, temperature requirement, chemical exposure, and application purpose.
5) Can you provide samples and bulk supply?
A: Yes. Sample support and bulk supply can be discussed based on the target size, material, and order quantity.
