1.The original material of the product
PU is the abbreviation of Polyurethane. The Chinese name is polyurethane. It is abbreviated as PU. It is made of a polyhydroxy compound and a diisocyanate, or a polyisocyanate under the condition of suitable catalysts and additives. It is a new type of advanced construction. Decoration information.
GRC is the abbreviation of Glassfibre Reinforced Concrete, the Chinese name is glass fiber reinforced concrete. GRC is a composite decorative building material line made of alkali-resistant glass fiber as the reinforcing material and cement mortar as the matrix material, and then produced through production processes such as spraying, vertical mold casting, extrusion, and slurry.
2. Density and component
Judging from the density and weight of the product, the PU Molding is a kind of foam material, and the quality is very light. Take the molding as an example. The density is about 200-220kg/m3. Due to its light weight, it will not cause great damage to people even if it is dropped. This is also the main reason why people prefer to use PU products to decorate the interior in areas such as Taiwan and Japan where earthquakes are frequent. The GRC molding has no advantage in this respect. Because the density of the GRC molding is as high as about 1800-2100kg/m3, the component is 8 times that of the PU molding.
3. Endurance
PU molding is made by foaming a variety of chemical materials and has good resistance. Together, special ingredients can be added at the time of production to make flexible molding that are easy to bend, which is very suitable for wrapping and making various shapes. GRC products, as a kind of rigid material, lack patience, are fragile and fissile, and are not as sensitive as PU in terms of styling.
4. Environmental protection
From the perspective of green environmental protection, the raw materials of new PU products are mostly derived from plant fibers, such as straw, straw, wood chips, etc., without logging, and can maintain the green plants well. Moreover, it takes only 40 to 50 years for the PU products to be completely degraded (the plastic needs 200 years to degrade, and the degradation is not complete). The GRC product is a kind of non-environmental protection material. Although it can be recovered and used later, the recovery cost is higher.
