Polyurethane special molecular sieve is a high-performance adsorbent designed for efficient moisture removal and gas purification in polyurethane production and processing. Featuring an optimized microporous structure with superior adsorption capacity, it selectively captures water molecules and other impurities, preventing unwanted side reactions and enhancing product stability. This molecular sieve is widely used in polyurethane coatings, adhesives, foams, and elastomers, ensuring reliable moisture control for improved material performance.
Product Overview
The Polyurethane Special Molecular Sieve is a highly efficient adsorbent designed specifically for use in the production of polyurethane products. It effectively adsorbs moisture and impurities generated during the manufacturing process, ensuring the stability and quality of the final product. In addition to preventing foam formation and extending the shelf life of polyurethane products, the sieve acts as a selective adsorbent to remove gases such as CO₂ and H₂S, ensuring superior product quality and performance.
Key Features
- High-Efficiency Adsorption: Effectively absorbs moisture and harmful gases, preventing any negative impact on the quality of polyurethane products.
- Preserves Physical and Chemical Properties: The sieve does not alter the basic properties of the polymer during use, ensuring the integrity of the end product.
- Extended Product Shelf Life: Helps prevent foam formation, improving the stability and longevity of polyurethane products.
Applications
- Polyurethane Production: Used in the production of polyurethane coatings, adhesives, and sealants, it prevents moisture or impurities from interfering with the polymerization reaction.
- Coatings Industry: In the coating production process, the sieve adsorbs moisture and gases, improving the quality and stability of the coating.
- Adhesives and Sealants: Enhances the performance of adhesives and sealants while extending their shelf life.
- Selective Adsorption: Can be used to adsorb specific gases like CO₂, H₂S, and other impurities, ensuring the purity and high quality of the end products.
