Polyester Reinforced PVC Sheet

Product Detail

Polyester Reinforced PVC Sheet

Dayu Polyvinyl Chloride (PVC) waterproof  membrane ( polyvinyl chloride plastic waterproofing sheets backed with fabric ) is manufactured from pliable PVC with a reinforcement of non-woven polyester  as packing or a polyester fiber as middle reinforcement layer. 


   

The PVC contains stabilizers, which make the product resistant to high or low temperature deformation, UV-resistant and flame retardant.





Polyester reinforcement






Product features

• Long service life and weathering  resistance; and the materials can be used for 30 years on the roof and 50 years  underground.

• High tensile strength, great elongation,  and small size change during heat treatment.

• Good low temperature flexibility and  adaptability to environmental temperature changes

• Good resistance to root penetration. It  can be made for green roofs.

• Excellent resistance to puncture and  impact.

• Convenient for construction (can be  welded), solid and reliable, and Eco-friendly.

• Strong  resistance to chemical corrosion, suitable for special occasions.

Where  to use

• All  kinds of roofs, such as steel structure roof, planted roof etc.

• Underground  engineering, such as building basement, subways, tunnels, air raid shelter,  etc.

• Other  projects like artificial lake, dam, water reservoir, grain storehouse, etc.

 

Cautions

• Do not put the membrane on a  pollution, water and ice ground.

• Construction of waterproof  layer operations can't be crossed, device shall be installed on the waterproof  layer, parts should be done to strengthen the basis of device and to take  protective measures.

• Do not touch the waterproof  layer with thorn sharp objects after it's has been completed, don't put  sundries or any additional buildings above the waterproof layer to avoid  damaging it.




Storage

• Different types and specifications of the  products should be stacked respectively. Pay attention to ventilation. Storage  temperature should not be higher than 45?, flat storage stack height no more  than five layer, put single pile vertical, keep product away from acid, alkali,  oil, organic solvent, etc.

• Transportation to prevent tilt or lateral  pressure, cover with cloth if necessary.

• Under the condition of normal storage  & transportation, storage period is one year.
