Excellent Fire Resistance TPU Raw Materials Halogen Free For Cable
High quality TPU materials with excellent fire resistance halogen-free for cable
During combustion, the outer coating material of TPU is rapidly carbonized and expanded, forming a barrier burning layer outside the wire, so as to achieve a flame retardant effect. It can effectively protect the core or core wire, and does not need to worry about the combustion of flammable substances caused by dripping. Is the future trend of flame retardant materials.

How to choose Polyether (PTMEG & Polyester System) ?
1. Polyether system
Material characteristics: hydrolysis resistance, low temperature resistance, biological resistance
Recommended for use in: outdoor use, underground wiring, low temperature environment, etc.
For example: civil and military communication products (outdoor, field, underground), outdoor sports equipment (mountaineering, wading, etc.), energy (wind, solar, hydropower stations, etc.), charging piles (low-temperature environment).
2. Polyester System
Material properties: tensile strength, chemical resistance, excellent wear resistance
It is recommended to use in: indoor, relatively dry, chemical environment, high physical performance requirements, and high ambient temperature.
For example: machinery and equipment (assembly lines, robots) these products require high physical properties. Transportation (all kinds of vehicles, ships, aircraft) and other high-temperature use environment.
