In construction projects, the quality of waterproof materials directly affects the life of the building. TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) are two mainstream waterproof membranes, but their performance differences often make it difficult for users to choose. This article will help you find the best solution by comparing strength, environmental protection and cost.

Basic knowledge of TPO and PVC waterproof materials

2.1 What is TPO?

TPO is made from a blend of polypropylene and ethylene, and its surface is smooth and UV-resistant.

2.2 What is PVC?

PVC is made of polyvinyl chloride as the main material, and plasticizers are used to improve its flexibility. It is cheaper but easily deformed at high temperatures.

Key Performance Comparison: TPO vs PVC

How to Choose Based on Project Needs?

Choose TPO If:

• LEED-certified green buildings
• Regions with extreme temperatures
• Commercial roofs

Choose PVC If:

• Temporary structures
• Low-budget indoor damp proofing

Dawn TPO Material for Waterproof Membrane

The waterproof membrane prepared by Dawn TPO material can be applied to the preparation of (GB 27789-2011) H, L, P, and other waterproof membranes. That is, it cannot only be applied to roofs and other exposed waterproofing but also can be used for non-exposed waterproofing, such as tunnels and culverts. 9511M is suitable for non-exposed coils, 9513M is suitable for exposed coils with a 5-year warranty, and 9513MT is suitable for exposed coils with a 10-year warranty.
