High Temperature-resistance TPO
The modification of ATP for polyolefin elastomers mainly reflects the following technical characteristics:
1. Improved Low-temperature Resistance:
In the application of cable insulant, the modification TPO of ATP can not only meet the requirement of electric performance from the insulant but also display a more broad temperature resistant character——displaying excellent mechanical properties and aging properties at the test temperature of -50℃—+125℃. So, this is the optimized insulant for wires and cables which have special requirements for low-temperature resistance.
2. Improved shrinkage resistance:
The jacket made up of TPO wire and cable insulant from ATP keeps its section surface smooth and orderly with little retraction rate after immersing in solder machine (350℃/2″). In the application of high-temperature-resistant cables (temperature≤125℃) such as charging vehicle cables (EV Cable), equipment connection cables, etc., the jacket made up of TPO wire and cable insulant from ATP takes the place of XLPE materials to meet the requirements of insulant high-temperature aging and shrinkage for nominal cables. And this can simplify the processing procedures by a large margin and improve the processing efficiency and yield.
Application: TPO has the characteristics of small specific gravity, good impact strength, and low-temperature brittleness, and is suitable for applications in the cable industry.
