Anti-UV Thermoplastic Polyolefin Waterproofing Membrane

1. About product

Anti-UV TPO  roof waterproofing membrane is a type of polymer  waterproof material that made  by using polypropylene(PP) and rubber as main raw material, processed  by using unique formula  and advanced technique. It has good processing performance  and mechanical properties, as well as high strength welding performance. After adding a layer of fabric in between two TPO sheets, this composite  product has enhanced its physical properties including higher breaking  strength,better anti-fatigue and puncture resistance.
 Because the  white color TPO membrane can greatly reflect the sun rays and anti-ultraviolet,  it has been widely used in various kinds of roofing waterproof engineering.

3.Where to use

  • Construction roof (exposed roof, plant  roof, light steel roof, roof-garden waterproofing)

  • Underground engineering (basement,  tunnel, metro,etc.)

  • Reserve facilities  (barn,reservoir,etc.)

 

4.Functional advantages

  • TPO waterproof membrane combines the advantages of EPDM and PVC,  with superior weatherability, flexibility at low temperature from EPDM and  weldability from PVC.

  • Different from conventional plastic materials, TPO shows high  elasticity as rubber at normal temperature, while it can be shaped like plastic  at high temperature.

  • It is environmental  friendly since it doesn't  contain any harmful  element to  the plant roots and can  be recycled throughout its service lifetime.

  • Excellent aging  resistance, tensile strength and elongation.

  • Easy  operation. ---operation  can be done on wet substrate,direct  exposure to the air under  different weather conditions is allowed,re-welding is operable.

  • White  color TPO enhances the reflection  of sun rays and  resistance of the ultraviolet.

  • Resistant to the growth of mould and alga.
