Sisiyuan brand modified polypropylene fiber is an organic fiber specially developed for construction projects by Jiangsu Sisiyuan Fiber Co., Ltd. It has a trilobal or round cross-section, good alkali resistance, and good chemical stability. This product It is a chopped fiber made from polypropylene pellets, adding masterbatch, blending, spinning, winding, drafting and cutting using special processes such as anti-static and anti-aging.
It has good dispersion in mortar/concrete and strong gripping force. Tens of millions of fibers per cubic meter are distributed in three-dimensional random directions in the concrete. It plays a purely physical reinforcing role in the concrete and can effectively improve the performance of the concrete. The gripping force between fiber and base material can prevent, reduce and delay early plastic cracking, and better improve the comprehensive performance of mortar/concrete.
