KRS Synthetic Resin Roof Tile was co-extruded with three layer. The top layer is ASA (Acrylonitrile, Styrene and Acrylic Rubber) made by the world's top 500 enterprises SABIC. It is a kind of excellent weather ability engineering resin. The middle and bottom layers are PVC.

The outstanding performance of KRS Synthetic Resin include environment- friendly, recycled, long time color preservation, light weight and strong toughness, thermal and sound insulation, easy installation.

The Resin Tile have been widely used on the different roofs over 20 years in Europe. From 2000, it is also used on the "Flat to slope" roof in China and now become the most salable roof tiles and highest market share in "Flat to slope" project all over China.

Synthetic Resin Roof Tile Features

² Outstanding Weathering Ability: Long time color preservation, resistance to the extreme temperatures, corrosion resistance and fire resistance.

Long time color preservation: ASA is a kind of excellent weather ability engineering resin. It can last very long lifetime in the natural environment. As the top layer of KRS Synthetic Resin tile, it can keep both the stable physical performance and chemical performance even long time at UV sunshine, moisture, high temperature and low temperature. At the same time, it can keep the vivid color long time. According to the test result in such areas with intensive UV sunlight as Arizona and Florida, the ASA color is able to last over ten years with the color change of ΔΕ≤5.

Resistance to the extreme temperature: KRS Resin Tile can maintain stable physical properties under extreme temperature conditions from -40℃ to 80℃.

Corrosion Resistance: KRS Resin tile is able to resist corrosion of various chemical substances such as acid, alkali and salt. The experiment proves that the roof tile has no chemical reaction when it is soaked in salt, alkali and various acids below 60% over 24 hours. It is much suitable application area with often acid rain and coastal areas.

Fire resistance: KRS Resin Roof Tile belongs to flame retardant material. According to the GB8624-2006 standard test, the fireproofing class is B1.

² Excellent physical performance: good resistance to impact, enough loading capacity, light weight, low linear thermal expansion.

Good resistance to impact: The test shows that there is no any crack after 1Kg ball falling from 2 meters. KRS Resin Roof tile has also outstanding resistance to impact under low temperature.

Enough loading capacity: In cold area, KRS Resin roof tile is not damaged and broken while a lot of thick snows cover on the roof during the winter. The experiment shows the roof tile do not crack and break under loading 150Kg on the base of purlin space not over 660mm.

Light weight: The weight of resin roof tile is only 5.8Kg. It belongs to light construction materials. The Resin roof tile can reduce the weight of construction materials effectively and save the total cost of the construction. At the same time it is easily transported and lifted.

Low linear thermal expansion: KRS roof tile is a low linear thermal expansion of 4.9X10-5℃).

² Favourable application performance: Environment-friendly, Heat and thermal insulation, Waterproof performance, Self Cleaning, Quick and easy installation.

Environment-friendly: The Resin roof tile do not destroy land and does not contain asbestos and radioactive elements. It can be recycled.

Heat and Thermal Insulation: The coefficient of heat conductivity of KRS resin tile is 0.325w/m.k., which is 1/3 of clay tile's, 1/5 of cement tile's, and 1/2000 of color steel tile's.

Waterproof: Since the Resin roof tile is a much large sheet overlap one by one, the fewer installation overlap can increase waterproof performance greatly.

Self Cleaning: The surface of resin tile is glossy with lotus effect. It could be washed clean by rain and snow.

Easy and quick installation: Because the resin tile is a large sheet with light weight, it is easily loaded and transported. Certainly it can save the labour cost and installation cost.
