Product Informations

Biogas digester fabric is made of high-strength industrial polyester fibers and PVC membranes through the laminating process. Due to the composition of red mud, it has the characteristics of being more weather-resistant, UV-resistant, flame-retardant, weather-resistant, and low-temperature resistant than ordinary PVC biogas digesters. In general, it is better suited for use in areas with a large temperature difference between day and night.

From raw materials such as fiber and resin powder to PVC flexible fabric, Foresight has a complete industrial chain.The system has obvious advantages. The production process is controlled layer by layer and comprehensively balances all key indicators, which can be customized according to the customer’s requirements in different environments. We are committed to providing users with the safest and most cost-effective solutions.

The red mud biogas digester fabric adopts red mud material, which has better UV-resistant, light-resistant, anti-corrosion, and anti-oxidation performance than ordinary biogas fabric. It is suitable for areas with a large temperature difference between day and night and strong outdoor UV when using biogas digesters. It has good weather resistance and extends the life of biogas digesters by 5–10 years.
