PVA Fiber is mainly used in sheet and section material, and could prevent micro-crack of concrete caused by the plastic shrinkage. 

This kind of environmental product is gradually taking place of asbestos and becomes a new kind of material.

Function

*  Anti-crack and anti-infiltration.

The fibers distribute in the mortar and concrete in different directions, which could prevent the happening and development of crack.

*  Anti-impact and anti-shock.

Absorb the impact power and improve the anti-impact capacity.

*  Anti-frost and anti-fatigue.

Relieve the temperature stress, increase the anti-frost and anti-fatigue capacity.

*  Anti-rub.

Decrease dusting, flaking, weathering of the concrete roads.

*  Increase toughness .

Improve brittleness of the concrete and increase the anti-break capacity.

*  Weight reduction.

Increase the anti-stretch and anti-cut capacity of the concrete, so the cross section size of the ready-made sections are decreased,

then decrease the weight of itself.

      

Application

*  Take place of asbestos and asbestos

cement products.

*  Light wallboard, insulation board and

other building material.

*  Make component of concrete, tubing

and board.

*  Large acreage concrete pouring, such

as quay.

*  The roof, basement of industrial and

residential building.

*  The sprayed concrete, such as

tunnel,mine, culvert and side slope.
