- customized formulations — a wide range of solutions matched exactly to the type of polyurethane and the requirements of the final product.
- minimum accumulation — technology that prevents residues on the mold and significantly reduces unplanned production downtime.
- improved Cycle Time — quick and easy release of the product, allowing a high pace of work and reduced waste.
High-quality release agents are the key to a stable, fast, and efficient production process, ensuring a perfect surface finish and an extended mold lifespan. Polyurethane Ltd. manufactures and supplies the leading solutions required for the polyurethane industry.
Customized solutions according to chemistry and application We offer a wide range of formulations suited to the polymer type, the requirements of the final product, and the production process:
- liquid release agents — sprayable solutions for efficient and simple production, particularly suited to high-output industrial production lines; creates a thin and precise release layer with a fast drying time.
- paste release agents — high-viscosity solutions that provide maximum protection against unwanted adhesion of polyurethane — for example, on exposed surfaces in production lines and around injection holes in pipe pouring; the exceptional release capability is ideal for application on surfaces with high absorption and wherever separation is critical.
- silicone-free systems — dedicated solutions for products intended for post painting, bonding, or coating after extraction from the mold, with no risk of adhesion problems.
- pastes and liquids for manual or automated application — suited to a wide range of application methods — from manual smearing to robotic spraying systems in large-scale production.
Operational and economic benefits | Operational & Economic Benefit | Description & Significance | | :— | :— | | Excellent release | Preventing unwanted adhesion using a small quantity of material. | | Minimum accumulation | Preventing residue on the mold and significantly reducing unplanned production downtime for cleaning. | | Variable surface quality | Full control over the finish of the final product (matte, glossy, or natural). | | Thermal stability | High stability at production temperatures, preventing breakdown of the release layer. | | Improved Cycle Time | Quick and easy release allowing a high pace of work and reduced production waste. |
Key applications
