Chemical Composition of PG Heat Shrink Tubing
PG tubing is formulated using cross-linked polyolefin, a tough, heat-shrinkable thermoplastic polymer known for its high dielectric strength and resilience. The core composition includes:
- Base Polymer :
- Polyolefin (e.g., polyethylene or EVA copolymers) – offers flexibility and excellent shrink performance
- Cross-Linking Agents :
- Enhance structural integrity and temperature resistance
- Flame Retardants (Halogen-free) :
- Phosphorus-based compounds to reduce flammability without releasing toxic halogen gases
- Antioxidants & UV Stabilizers :
- Protect against thermal oxidation and environmental aging
- Colorants (Optional) :
- Used for wire coding and product differentiation
- Polyolefin (e.g., polyethylene or EVA copolymers) – offers flexibility and excellent shrink performance
- Enhance structural integrity and temperature resistance
- Phosphorus-based compounds to reduce flammability without releasing toxic halogen gases
- Protect against thermal oxidation and environmental aging
- Used for wire coding and product differentiation
This composition ensures chemical resistance to oils, solvents, and fuels, while delivering electrical insulation that is stable and reliable across a wide temperature range.
