What are the main uses of high-temperature leather release paper?

High-temperature leather release paper is a special release paper used in high-temperature environments, mainly applied in leather production and related fields. The following are its main uses:
Artificial leather production
Embossing and forming: In the production of artificial leather, high-temperature leather release paper is often used in the embossing process. The release paper is attached to the unformed artificial leather material, and through high-temperature rolling, the patterns on the release paper are transferred to the surface of the artificial leather, giving it various beautiful textures, such as crocodile patterns, snake patterns, cowhide patterns, etc., increasing the simulation degree and aesthetic appearance of the artificial leather.
Coating carrier: As an important carrier in the coating process, the release paper can evenly coat various coating materials on the surface of the artificial leather. Through high-temperature treatment, the coating can be better bonded to the leather substrate, improving the water resistance, wear resistance, and aging resistance of the artificial leather. For example, in the production of some high-end artificial leather, a special polyurethane coating is applied. After high-temperature curing, it can endow the leather with good gloss and softness while enhancing its durability.
Synthetic leather production
Auxiliary shaping: In the production process of synthetic leather, high-temperature leather release paper helps with the shaping of the synthetic leather. The raw materials of the synthetic leather are compounded with the release paper, and through stretching and shaping under high-temperature conditions, the release paper can ensure that the synthetic leather maintains a stable shape and size during the forming process, preventing deformation or shrinkage and improving the quality and consistency of the product.
Improving the hand feel: By adding specific additives to the release paper or performing special surface treatments, during the high-temperature lamination process, these substances are transferred to the surface of the synthetic leather, thereby improving the hand feel of the synthetic leather, making it softer and more comfortable, and closer to the texture of natural leather.
Other related fields
Leather repair: In the leather repair industry, high-temperature leather release paper can be used to repair scratches, abrasions, and other damages on the leather surface. The release paper with repair materials is covered on the damaged part, and through high-temperature ironing, the repair materials are closely bonded to the leather surface to achieve the repair effect. At the same time, the release paper can prevent the repair materials from sticking to the iron or other tools.
Leather decoration: It is used for the local decoration of leather products, such as making leather labels, decorative patches, etc. The high-temperature leather release paper is used to transfer the designed patterns or texts to the leather, adding a unique decorative effect to the leather products and increasing the added value of the products.
