Yes, we can provide you with small product samples, but you will need to pay for shipping.

Normally, a 50% deposit is paid first, and the remaining 50% is paid before shipment. We can accept commonly used payment methods such as TT, Western Union, etc

We will arrange production after receiving the advance payment, and usually can ship within 15-30 days.

TPO is a high molecular weight thermoplastic polyolefin, mainly composed of carbon atoms and hydrogen atoms, without any plasticizers or chlorine atoms. It has both the weldability of plastic and the aging resistance, high temperature resistance, and low temperature resistance of rubber.

Yes, TPO membrane does not contain chlorine elements or harmful components, and will not release harmful components during production, construction, and use.

No, TPO membrane does not have fire resistance and its own components do not contain flame retardant elements.

TPO membrane can function normally within the temperature range of -45~115 ℃, meeting the environmental requirements of the vast majority of regions worldwide.

In order to ensure construction quality, the construction environment temperature needs to be maintained at 5-35 ℃.

PVC waterproof membrane is a flexible polymer waterproof membrane made of PVC resin as the main raw material, mixed with stabilizer, plasticizer, anti-aging additives and fillers. It is divided into homogeneous PVC board and reinforced PVC board embedded with glass fiber or polyester mesh to improve tensile strength and dimensional stability.

PVC membrane is environmentally friendly under normal circumstances, but it releases corrosive hydrogen chloride smoke during high-temperature combustion. Its environmental friendliness is not as good as TPO membrane.

PVC waterproof membrane has inherent flame retardant property due to high chlorine content in its molecular structure. It features self-extinguishing performance: the flame will die out once the external fire source is removed, and a carbonized protective layer forms on the surface to slow flame spread.

PVC membrane can work normally within the range of -20 ℃ to+70 ℃, and can meet the environmental needs of most regions around the world.

In order to ensure construction quality, the construction environment temperature needs to be maintained at 5-35 ℃.

HDPE(high density polyethylene) also called HDPE geomembrane. It is a black flexible impervious coiled material made of high density polyethylene resin as raw material, antioxidant, carbon black, anti-aging additives, extrusion blow molding or calendering, and belongs to polyethylene macromolecule impervious material.

HDPE waterproof membrane (geomembrane) is an environmentally friendly polymer lining. It is made of high-density polyethylene and does not contain plasticizers, chlorine, or harmful phthalates, so there will be no toxic substances infiltrating the soil or water during long-term use, making it safe for fish ponds and drinking water tanks.

HDPE membrane can work normally within the range of -40 ℃ to 60 ℃, which can meet the environmental needs of most regions around the world.

To ensure construction quality, the construction environment temperature needs to be maintained between 5 ℃ and 30 ℃.
