Polyvinyl alcohol fiber and Polyester fiber,a product independently researched and developed by china Polypropylene fiber manufacturer company ,is designed for use in concrete to increase the internal quality, reduce maintenance cost and prolong service life of cement mortar and concrete.
As one of the leadings suppliers & exporters of concrete fibers in China,
we supply all kinds of fiber for concrete reinforcement, such as:
Polypropylene fiber ( PP fiber ) Monofilament / mesh / fibrillated / twist / wave etc...
Polyester fiber ( PET fiber )
Polyacrylonitrile fiber ( PAN fiber )
Polyvinyl alcohol fiber ( PVA fiber )
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles . An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.
Polypropylene has a relatively slippery "low energy surface" that means that many common glues will not form adequate joints. Joining of polypropylene is often done using welding processes.
In 2013, the global market for polypropylene was about 55 million tonnes
Polyester is a category of polymers that contain the ester functional group in their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.
Depending on the chemical structure, polyester can be a thermoplastic or thermoset. There are also polyester resins cured by hardeners; however, the most common polyesters are thermoplastics.
PVA Fibers (polyvinyl alcohol) are high-performance reinforcement fibers for concrete and mortar. PVA fibers are well-suited for a wide variety of applications because of their superior crack-fighting properties, high modulus of elasticity, excellent tensile and molecular bond strength, and high resistance to alkali, UV, chemicals, fatigue and abrasion. PVA fibers are unique in their ability to create a molecular bond with mortar and concrete that is 300% greater than other fibers.
