Why Choose Semi-Bright High Temperature Release Paper for Composite Materials?
As industrial processes advance, traditional release papers often fail to maintain production efficiency and consistent quality under high-temperature conditions. High temperature release paper has therefore become an indispensable material in industries such as synthetic leather, composite films, adhesives, and coating materials. Among these, semi-bright high temperature release paper stands out for its heat resistance, surface gloss, and stability, making it widely applied in various high-temperature composite processes.
Definition and Characteristics
High temperature release paper is a type of industrial paper coated with specialized release materials, designed to withstand high temperatures and pressures while providing excellent release performance. Its main characteristics include:
- Heat Resistance: Can withstand continuous use at temperatures ranging from 150°C to 250°C or higher, suitable for hot pressing and baking processes.
- Release Stability: Uniform coating with moderate adhesion ensures smooth separation of materials during thermal processes, preventing sticking or surface damage.
- Surface Gloss and Smoothness: Semi-bright high temperature release paper combines moderate gloss with smoothness, ensuring both release performance and visual quality.
- Chemical Resistance: Resistant to acids, alkalis, and various solvents, making it suitable for coatings, adhesives, and other composite applications.

Manufacturing Process of High Temperature Release Paper
The production of high temperature release paper relies on high-quality base paper, precise coating technology, and strict quality control. Anhui Honghuan New Material Technology Co., Ltd. integrates R&D, production, and sales, demonstrating the key steps in manufacturing high temperature release paper:
-
Base Paper Selection and Treatment
High temperature release paper uses heat-resistant, high-tensile specialty paper as the base, which undergoes degreasing and smoothing to ensure uniform thickness before coating. Honghuan maintains a stable supply chain for base paper, ensuring reliable material sourcing.
-
Coating Process
Using precision coating equipment, silicone or specialty polymers are evenly applied to the paper surface, forming a heat-resistant, easy-release layer. Coating thickness and uniformity directly affect release performance.
-
Drying and Curing
Coated paper passes through a high-temperature drying system to cure the coating. Precise temperature control ensures adhesion and thermal resistance meet design specifications.
-
Testing and Quality Control
Equipped with pilot coating machines, analytical instruments, and laboratories, Honghuan tests each batch for release force, heat resistance, surface gloss, and thickness uniformity to ensure consistent quality.
-
Cutting and Rolling
Rolls are cut according to customer specifications, with widths ranging from 1,600 mm to 2,350 mm. Low minimum order quantities (2,000 meters per roll) provide flexibility for small-scale orders.

Applications and Industry Value
High temperature release paper provides significant functional value across multiple industries:
-
Synthetic Leather
In synthetic leather production, high temperature release paper is used for hot pressing and film transfer, ensuring the surface is free of adhesion and defects. Semi-bright high temperature release paper is preferred for high-end synthetic leather due to its balance of gloss and heat resistance.
-
Composite Materials
During hot-pressing of composite panels and fiber-reinforced materials, release paper protects materials from sticking to molds while withstanding prolonged high temperatures, preserving structural integrity.
-
Adhesives and Coating Processes
High temperature release paper resists heat-curing and baking processes, preventing adhesive residue on substrates and improving production efficiency.
-
Specialty Packaging
In high-temperature packaging or thermal protection applications, release paper maintains dimensional stability and prevents contamination.
