First, fire door core board special polypropylene fiber product description
"Siliyuan" brand modified polypropylene fiber is an organic fiber developed by Jiangsu Siliyuan Fiber Co., LTD., which is specially used for construction projects. This product is a cut fiber made by adding polypropylene granule to master material, blending, spinning, winding, drawing and cutting by using special processes such as anti-static and anti-aging. It can effectively improve the binding force of fiber and base material and be applied to mortar/concrete. It can prevent, reduce and delay the early plastic cracking, and improve the comprehensive performance of mortar/concrete.
Parameters and properties of polypropylene fiber for fire door core plate:
"Filar wire" brand modified polypropylene fiber cross section for three leaf or round, good alkaline resistance, good chemical stability, good dispersion in mortar/concrete, strong grip, each cubic meter of tens of millions of fibers three-dimensional distribution in the concrete, in the concrete plays a pure physical reinforcement role.
