Application:
Polypropylene insulation compound is a kind of mixing modification compounds, which regard polypropylene resin as the basic raw material.
This product has excellent electricity property, physical and mechanical property, and high-low temperature resistant properties. It not only
can be used for the insulation of in-house communication cables, but also for the insulations of high-temperature resistant and anti-fold
situations.
Processing Indicator
Recommend to use single-screw extruders with L/D= 20-25.
