POP Fiber is a fiber-reinforced Plaster of Paris (POP) material used in construction and interior decoration. It is made by combining POP with reinforcing fibers to improve strength, flexibility, crack resistance, and durability. POP fiber is commonly used for decorative ceilings, wall designs, cornices, partitions, mouldings, and other interior finishing works. It is lightweight, easy to shape, and provides a smooth, attractive finish.
