UV Protective Yellow Outer Film for UV Cured Repair Hoses

This UV Protective Yellow Outer Film for UV Cured Repair Hoses is manufactured from PA/PE co-extruded material with special anti-UV additives. It achieves up to 99.9% UV blocking performance to avoid premature curing of internal resin during storage, transport and construction, while preventing resin leakage and contamination. The film features excellent puncture resistance, oxygen & water vapor barrier properties, food-grade, BPA-free, residue-free and eco-friendly. Available in customizable color, thickness and width, it is widely applied as outer protective film for CIPP pipeline repair liners and other special UV shielding scenarios.

    Product Introduction:

    UV Protective Yellow Outer Film for UV Cured Repair Hoses uses PE, PA, and special UV resistant functional materials, forming a type of co extruded material through a co extrusion blown film process. This thin film material has a UV transmittance close to 0, making it an excellent anti UV protection material. The UV transmittance is close to zero, which can prevent resin materials from being contaminated or pre cured, maintain their quality and performance, avoid UV curing of materials before storage, transportation or construction, and ensure their fluidity. This type of film has puncture resistance, is not easily damaged, extends product life, blocks oxygen and water vapor, and maintains material stability. The raw materials used are safe and environmentally friendly, comply with green packaging standards, and have no residues. We support customization of various colors, thicknesses, and sizes to meet different needs.

    Product Advantages

    • Raw Materials: Manufactured with food-grade raw materials and BPA-free. It can be used for rehabilitation of drinking water pipelines and pipelines in food processing plants, allowing direct contact with water.
    • Excellent Toughness: Adopts 11-layer co-extrusion blown film technology. Multi-layer polyamide (PA) delivers outstanding tear resistance, puncture resistance and wear resistance.
    • Great Flexibility: Thanks to the multi-layer co-extrusion process, the film features superior stretchability and good softness. The lining material maintains excellent flexibility over a wide temperature range, accommodating diameter variation and bending of pipelines.
    • Easy Processing: Low-friction film facilitates convenient installation. It can be processed by high-temperature steam and UV curing.
