Environmental protection and energy conservation,Corrison resistance,Impact and low temperature resistance.long life
Our company introduces the international advanced co-extrusion technology and appliesthe first class equipment to produce this kind of new roof tile. The surface film is PMMAmaterial , which is a kind of super highly anti-wea thering engineering resin materia lmanufactured by ATOGLAS company in France.
1.Environmental protection and enercy conservation
It is a kind of environmental-friendly, energy conservation and recycling buildingmaterial popular in developed and developing countries.
2.Color lasting
The super high anti-weathering engineering resin manufactured by ATOGLAS inFrance is selected as the surface material , which has extra lasting performancein the natural environment. Even it is exposed in the conditions of ultra violet ray,moisture, high and low temperature for a long term, it still can maintain the stabilityof the color. According to the outdoor service result in Arizona and Florida in USA
which have strong sun shine, it is proved that E<5 can be guaranteed within
10-15years.
3. Load bearing
PMMA roof tile has very good load bearing performance. No damaged when 150kgis evenly loaded with the support distance being 750mm.
4. Sound and heat isulation
The coefficient of heat conductivity is 0.325w/m.k,which is about 1/3 of clay tile,
1/5 of 10-mm-thick cement tile, and 1/2000 of 0.5-mm-thick color-coated steel tile.
It can well absorb the noise when influenced by storm,hail and windstorm etc..
5. Stable volume
The expansion coefficient is 4.9x10- 5 °C . The tile has the bi-direction tensionperforman ce on the geometri c shape design. Even if the temperature changesa lot, the tile expansion can be absorbed by itself to ensure its stable geometric
dimension.
6. Corrosion resistancePMMA roof tile can resist the chemical corrosion of acid, alkali, salt etc. for a longtime. The test proves that there is no chemical reaction when dipped in the salt,alkali and below 60% acid.
7. Good water resistanceThe surface material of PMMA is compact and does no absorb water without theproblem of water penetration by micro pores. The single sheet of the resin tile is bigand there is very few joint on the roof. The connecting point is tightly connected,therefore the tile has the outstanding water resistance performance.
8. Impact resistance and low temperature resistance
Physical test of a 1 kg steel ball freely falls on the tile from 2 meters height withoutany crack, and there is no damage when the ball falls ten times at low temperature.After 10 freezing and melting cycles, the product has no blow, bubble, stripping andcrack.
9. Light weightThe weight is 6 kg per square meters. Belonging to light structural material, it caneffectively reduce the load of the building and save the consumption of buildingframework materials. In the mean time, it is easy to be handled and lifted, whichreduces the construction cost.
10.Difficult to be burned The main body material polyvinyl chloride resin, and its chemical performancedetermines that it is diffi cult to be burned.
