Superior Mechanical And Physical Properties: HSHM PVA fiber has high tensile strength and modulus, low elongation. The tensile strength is not inferior much to steel bar and elastic modulus can match with concrete’s. It can improve the early strength of concrete, but also the tensile strength of concrete in the late, can greatly save construction curing time, shorten construction cycle.
.
High Affinity With Cement: HSHM PVA fiber has good affinity properties with cement and the bonding strength is better than that of nylon 6, polypropylene, polyester fiber etc. Because of the unique molecular structure, PVA fiber plays the reinforcing function on the interface bonding with brittle material cement.
Good dispersion: HSHM PVA fiber is not adhesive between each other and can disperse well in water. Fiber in the concrete evenly disperses, randomly distributes then overlaps into a three-dimensional network structure. In the concrete it changes the brittleness of concrete, increases its toughness, improve the concrete crack resistance, impermeability, frost resistance, impact resistance and other properties of concrete, so as to improve the overall quality and the durability of concrete.
Good Alkali And Weather Resistance Performance: HSHM PVA fiber has good chemical stability and there is no chemical reaction with any material after mixing with concrete. The acid and alkali resistance, chemical resistance are superior to those of synthetic fiber, nylon 6, polyester and other fiber.
Good Light fastness And corrosion resistance: Under the long time sunshine, The strength loss rate of HSHM PVA fiber is significantly lower than the other fiber. The fiber will not be moldy, corrosion, and moth-eaten buried long time.
Green Environment Protection and No Pollution: No dust inhaled into the lungs and no poisonous gases being burning in transport and use process.

Application
1. HSHM PVA fiber as the ideal substitution of asbestos has not only excellent tensile strength, impact strength, chemical resistance and cement alkali resistant but also has no dangerous to the human body and the environment. It can be made of cement products such as high strength decorative material replacing asbestos, but also in the high grade road construction, instead of asbestos, the fiber mixes with cement concrete and can greatly improve the tensile strength of concrete.
2. As cement concrete or mortar’s anti-crack materials, it can not only increase the tensile strength of concrete, but also can reduce the concrete internal microcrack and can effectively suppress the crack extension.
3. HSHM PVA fiber can replace the steel as bar strip in construction of water conservancy project.
4. Used as plastics reinforced material and manufacture of safe and riot helmet.
5. HSHM PVA fiber can replace mightiness rayon used in the manufacture of radial tire or diagonal tire cord.
6. Used as the rubber reinforcing material manufacture of conveyor belt, fire hose, braided hose etc.
