TPO vs PVC

While both TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride) are widely used materials in industrial textiles and roofing, TPO has a number of distinct advantages in specific applications.

1. Environmental friendliness
TPO is free of harmful chemicals like chlorine and heavy metals, making it fully recyclable and environmentally friendly. This aligns with sustainable construction practices and eco-conscious industries.
PVC contains chlorine and may release harmful chemicals (such as dioxins) during the manufacturing or disposal process, which gives rise to environmental concerns.

2. Weight and flexibility

TPO is a lighter and more flexible material than PVC, which makes it easier to handle, transport and install. Its flexibility also allows it to adapt to structural movements and extreme temperature changes.
PVC is a heavier and less flexible material, which can result in increased labour costs, particularly in colder climates.

3. Resistance to UV and Heat
TPO offers excellent UV resistance and natural heat-reflective properties, which help to reduce energy costs in outdoor applications such as roofing and protective coverings.
PVC offers good UV resistance, but is more prone to heat degradation over time. Additional coatings are therefore required to match the performance of TPO.

4. Seamless Heat Weldability
TPO allows for easier heat welding, creating strong, seamless, watertight joins that are ideal for applications such as roofing membranes.
PVC: While also heat-weldable, its seams can be more prone to weakening over time due to the plasticisers used, which may affect the product's durability.

5. Chemical Resistance
TPO demonstrates robust resistance to a range of industrial chemicals, oils and greases, making it an ideal choice for use in harsh environments.
PVC: While it is chemically resistant, prolonged exposure to certain oils can cause degradation.

6. Longevity
TPO is renowned for its longevity in outdoor and industrial settings, retaining its functionality even after prolonged exposure to UV radiation and the elements.
PVC is a durable material, but it may lose flexibility and degrade more quickly in extreme environments without additional treatments.
In conclusion, the key points to take away from this comparison are as follows:
TPO is an excellent choice for industries or projects that prioritise eco-friendliness, cost-efficiency, UV/heat resistance and lightweight flexibility. While PVC offers advantages in terms of puncture resistance and colour options, TPO often delivers a better balance of performance and sustainability for many applications.
