1、 Glass fiber felt plays a role as a carrier in the process of making asphalt tile, which not only makes the product have good waterproof performance, but also can maintain the waterproof performance even if the tile surface is damaged. So that the product can withstand the shock generated during production, transportation, construction and use.
2、 The asphalt adopts petroleum oxidized asphalt, which has large extensibility and strong adhesion, has high absorption of filler, is conducive to the fire resistance of the product, and can bond all materials together, so that the colored asphalt tile can resist wind and rain erosion for a long time, maintain the product performance in severe cold and heat, and play the role of moisture and oxidation resistance.
3、 The colored mineral particles on the surface of the colored mineral particle asphalt tile can protect the asphalt surface from direct sunlight, make the asphalt not easy to age, prolong the service life of the tile, enrich the color of the product, and improve the fire resistance of the roof tile.
4、 Self sealing adhesive tape is attached to the back of color asphalt tile. After the colored asphalt tiles are laid on the roof, the self-adhesive will be activated under the irradiation of the sun, resulting in viscosity, so that the upper and lower colored asphalt tiles can be firmly bonded together to ensure the integrity of the roof.
5、 Limestone is commonly used as filler (fine sand surface). Filling material has several advantages for roof tiles. It can enhance the fire resistance of products, moderately improve the weather resistance and elasticity of roof tiles, and reduce the product cost.
