[0002] MPP power pipe, full name MPP power cable protection pipe, is a pipe made of modified polypropylene (MPP) as raw material. The advantages of MPP power pipe include good electrical insulation, high heat deformation temperature and low-temperature impact strength, strong tensile and compressive properties, light weight, smooth inner wall, small friction coefficient and can be hot-melt welded.
