They are necessary auxiliary materials in the production process of radial tires. Rubber films should be prepared before the production of treads, crowns, side walls, double lamination and belts. Our isolating preservative films, which are soft, stiff and smooth, can fully cling to the pre-made rubber films and are easily peeled off. So they are ideal preservative materials for rubber films. Various performance indexes include: Tensile strength, elongation at break, tear strength, melting point, copper content, manganese content and acetone extract can meet application requirements. Our products are favored by major global tire manufacturers.
