Product Advantages

Foresight has more than 15 years of experience in the production of red mud biogas fabric, a strong scientific research team, more than ten engineering and technical personnel graduated from professional colleges, and more than 30 high-speed rapier looms to meet various needs. with an annual output of more than 10,000 tons of various types of calendered films and an annual output of more than 15 million square meters of fabrics.


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


The water bag fabric is light in weight, easy to transport.
