    PP Liner For Rubber Sheet is a woven polypropylene (PP) fabric used as a release or protective layer in rubber sheet production, storage, transport, and as interlayer separation.
    It functions similarly to B8 liner but is lower cost and lighter, with lower heat resistance, suitable for low-temperature or non-vulcanized applications.
    PP Woven Liner for Rubber Sheet is a lightweight, low-cost, low-to-medium temperature release fabric. It is mainly used for rubber sheet storage, transport, roll separation, or low-temperature anti-stick applications, but is not suitable for high-temperature vulcanization or long-term repeated use.

    Technical Data

    Technical Parameter PP Liner (Pure Polypropylene) Notes
    Material Composition Warp: Polypropylene; Weft: Polypropylene Defines the fundamental physical and chemical properties.
    Basic Strength (Tensile) Medium-High B8 is generally stronger and tougher due to the Nylon component.
    Abrasion Resistance Good A key factor determining the liner's reusability and lifespan.
    Dimensional Stability Good Polyester contributes to better stability under varying temperature and humidity.
    Chemical Resistance Excellent PP is typically superior for resistance to acids, alkalis, and many solvents.
    Release Force (Peel Strength) Controllable Both depend heavily on the specific release agent coating and fabric weave density.
    Impression Clarity Good B8 is often preferred in applications like tire treads for optimal de-aeration channels.

    Advantages

    PP Liner For Rubber Sheet is a Ideal for large-area sheet separation or single-use applications.revents short-term adhesion between rubber sheets, rolls, or mold surfaces.Suitable for Low-Temperature or Non-Vulcanized Applications.Polypropylene is recyclable, non-toxic, and chemically stable at normal temperatures.

    Excellent Chemical Resistance,PP exhibits high inertness and resistance to most acids, alkalis, salt solutions, and various organic solvent.Suitable for isolating rubber formulations that contain chemically active ingredients (e.g., specific accelerators, bonding agents, or acidic/alkaline fillers), preventing liner corrosion or contamination.
