use the LG chem high weatherability engineering resin as the surface material of
the tile. In in the natural environment, our product possesses exceptional durability, under exposing to ultraviolet
light, moisture, high and low temperature conditions, 28 years of the stability of color can be promised. Δ E ≤5

Zhongfu synthetic resin roof tile’s coefficient of thermal conductivity is 0.293 w/m.k, about a third of clay tile, one
fifth of 10 mm thick cement, one over two thousand of the color 0.5 mm steel. Phoneme determined through
experiments show that, under heavy rain, hail, gale, such as the weather, Zhongfu synthetic resin roof tile still
can absorb well

select high weatherability resin, density and no water absorption, no water
seepage problems of micro porous, big size area, less roof seam, contact closely. Thus it has excellent
waterproof performance, can save the waterproof layer.

Zhongfu synthetic resin roof tile’s main body material is PVC resin. Its chemical properties of materials
determines its flame retardant properties, fire prevention performance achieve B1 level.

belongs to the light structure material, can effectively
reduce the load of the building, enhance security, and at the same time it can save construction main body
material, convenient carrying, lifting, reduce construction cost.

Expansion coefficient of Zhongfu synthetic resin roof tile is 4.93 x 10-5 (1/5 ℃), it possesses low expansion and
the bidirectional tensile properties, even the temperature change is very huge, it also can ensure thethe same
geometric size.

Another basic characteristic of impact resistance is not easy be broken by the natural force, because of we
adopt high weather resistance resin with high impact resistance. The fall test shows that no crack by 1 kg of
steel ball fall free from 3 m high, no broken with10 shock performance under low temperature.

Zhongfu synthetic resin roof tile is not easy absorb dust itself. It looks clean as new after the rains washed out,
no fouling washed.

Zhongfu synthetic resin roof tile can resist acid and alkali, salt and other chemical corrosion. No chemical reaction
under the experiment for alkali, salt, and less than sixty percent of the various kinds of acid for 24 hours .

hongfu synthetic resin roof tile achieve assessment by development science and technology center of
national ministry of construction department. Product environmental protection, energy saving and renewable
use, is popularized to support new product "environmental protection, energy saving"in our country at present.
