Ultra-Heavy Release PP Film: High-Durability Protective Solution for Demanding Applications

Introduction

Ultra-Heavy Release Polypropylene (PP) Film is a robust, thick-gauge engineered film designed for industrial applications requiring exceptional strength, dimensional stability, and reliable release performance. With thicknesses ranging from 250μm to 1000μm, this heavyweight PP film provides superior protection against abrasion, punctures, and extreme processing conditions, making it ideal for high-stress environments in composites, construction, and heavy-duty adhesive systems.

Key Features

Exceptional Thickness & Rigidity (250–1000μm) – Offers unmatched structural support for heavy materials and high-pressure processes.

High Tensile & Tear Strength – Resists deformation and damage during handling, lamination, or molding.

Enhanced Thermal Resistance (Up to 150°C) – Maintains stability in autoclave curing, hot pressing, and other high-temperature applications.

Customizable Release Force – Available with silicone or non-silicone coatings for tailored adhesion control (light to heavy release).

Chemical & Moisture Barrier – Protects against solvents, oils, and humidity in harsh industrial environments.

Smooth or Textured Surface Options – Ensures bubble-free layup in composite manufacturing or controlled adhesion in tapes.

Applications

Aerospace & Automotive Composites – Release layer for carbon fiber/epoxy prepregs during autoclave curing.

Heavy-Duty Adhesive Tapes – Carrier film for industrial mounting tapes and construction adhesives.

Molding & Casting – Non-stick surface for concrete molds, fiberglass layups, and rubber vulcanization.

Protective Covers – Temporary shielding for metal sheets, painted surfaces, and machinery during fabrication.
