Product Advantage
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.
To ensure that the JULI® tunnel/mine ventilation duct has excellent physical and mechanical properties, use a high modulus, high strength, low shrinkage polyester fiber as the base fabric.
Use high-quality raw materials to ensure that the JULI® tunnel/mine ventilation is environmentally friendly and has no odor, wear resistance, weather resistance, or folding resistance. The self-developed heat medium oil high temperature and high-pressure composite equipment are used to fit the fabric to ensure that the tensile strength, tear-resistance, and adhesion fastness of the fabric of the Juli tunnel air duct are highly balanced, the surface of the fabric is smooth, and the fabric is easy to unwind.
