4.Pcking:pp woven bag or carton
Polypropylene fiber is also called engineering fiber, concrete fiber, anti-cracking fiber, synthetic fiber or plastic fiber.
We use high tenacity polypropylene resin as the raw material and produce with special technics. Putting the pp fiber into concrete or mortar can control the microcrack caused by such factors as the plasticity contraction,air shrinkage and temperature change. Great prevention of cracks-being, improvement of the features of anti-cracks and permeation-resistance, shock and earthquake proof, all these have been good evidence for the wide usage of pp fiber--finish coat of road and bridge, mining and tunnel construction, railroad, high-rise building, consolidation of side, fire-protection infrastructure, concrete-mending, industrial civil use engineering, wall, basement, waterproof project of pool and roof garden, kinds of prefabricate concrete products etc.
