Flame retardant asphalt mastic
1. Description of the product
Mastic asphalt (MA) is a dense mixture consisting of coarse aggregate, and/or sand, and/or limestone fine aggregate, and/or filler and bitumen, which may contain additives (for example polymers, waxes). The mixture is designed to be of low void content. The binder content is so adjusted that the voids are completely filled and that even a slight excess of binder may occur. Mastic asphalt is pourable and able to be spread in its working temperature condition. It requires no compaction on site.
2. Application area
It is a building material that is used for paving, roofing and flooring. It also used in for sealing of any kinds of holes on the auto body, high building, electric power, chemical industry, metallurgy, electric wire, cable systems project, etc.
(2)Average density: white mastic≥1400 ;black mastic≥1600 (kg/m3)
(3)Fire Resistance: It cause no spark during construction, fire resistant after drying, and extinguishes in 1s after fire source taken away.
(4)Heat Durability: No flowing and foaming (placed at the temperature of 95°C~120°C)
(5)Frost resistance: No cracks or peeling off occur (exposed at -40°C ~+60°C for 2hrs)
(6)Drying Time: It can be touched with fingers after 5hr, while it costs 6days to dry completely.
Prevent the spread of fire, remedy the fire of international freeways, bridge and tunnel. It causes no spark during construction, and extinguishes in 1second after fire source taken away.
•Non-solidified, excellent elastic deformation, thus have good flame retardant;
•Non-toxic, odour less, no corrosive, environmental friendly;
•High temperature stability, low temperature crack resistance, water stability.
