Used for production of fiber cement as additives in the composition.
Pulp is used for: In the constuction for production of fiber-cement piates in the ratio of approximately 10 % , as asbestos substitute.
Users of the fiber cement plates seeking high performance and reliable green building materials products triedthis product in the accredited laboratories and proved that they are 100% free from asbestos or other harmful materials such as sepiolite, inorhanic fibers or formaldehyde.
Owing to its structure fiber cement plates are practically nonflammable and environmentally clean; heatproof and cold-resistant; corrosian, UV radiation and acid rain resistant; have antiseptic properties (no subject to rotting); shockproof; have high enough acoustic insulation (unlike the metal roofing); termite-proof; have different surface patterns (corrugated sheets, lug, zigzag); special coating (imitates wood or natural stone) may be applied to the surface; time of life of the fiber cement facing materials is only second to aluminium.
Pulp for fiber-reinforced cement is supplied to Thailand, Belgium, Brazil, Turkey, and Indonesia.
