The main types of heat shrink tubing include the following:
Classification by temperature grade:
Low-temperature heat shrink tubing: Suitable for occasions with low working temperatures, such as household appliances, electronic equipment, etc.
Medium-temperature heat shrink tubing: Suitable for occasions with high working temperatures, such as industrial equipment, automotive circuits, etc.
High-temperature heat shrink tubing: Used for insulation protection in extremely high temperature environments, such as aerospace, nuclear power plants, etc.
Classification by material:
PE (polyethylene) heat shrink tubing: Has good insulation performance and softness, and is often used for insulation protection of wires and cables.
PVC (polyvinyl chloride) heat shrink tubing: Has weather resistance, flame retardancy and certain mechanical strength, suitable for insulation and protection of outdoor wires and cables.
PTFE (polytetrafluoroethylene) heat shrink tubing: Has excellent corrosion resistance, high temperature resistance and electrical insulation performance, suitable for insulation protection in high temperature and high corrosion environments.
FEP (fluorinated ethylene propylene) heat shrink tubing: Similar to PTFE, but with a lower price, suitable for insulation protection in general high temperature environments. Classification by color:
Colored heat shrink tubing: Different colors can be selected as needed, which is convenient for marking and distinguishing circuits. Black, white and other single-color heat shrink tubing: Commonly used for general insulation protection, no special color requirements. Classification by special properties:
Flame retardant heat shrink tubing: It has flame retardant properties and can prevent the spread of fire to a certain extent. Waterproof heat shrink tubing: It has good waterproof properties and is suitable for insulation protection in humid environments.
