UV Absorber UV-B75

Product Overview

UV Absorber UV-B75 represents a premium class of liquid ultraviolet stabilizers engineered to protect polymer matrices from photodegradation. This high-efficiency additive is specifically formulated to absorb harmful UV radiation, thereby preventing chain scission and maintaining the mechanical integrity of sensitive materials. As a direct equivalent to market-leading standards, it provides robust protection against yellowing, cracking, and loss of gloss caused by prolonged exposure to sunlight and artificial weathering conditions.

Our manufacturing process ensures exceptional purity and consistency, making UV-B75 an ideal choice for demanding applications where long-term durability is critical. The liquid form factor facilitates easy incorporation into various formulation systems without requiring complex dissolution steps, enhancing production efficiency for downstream manufacturers.

Key Specifications

Industrial Applications

UV-B75 is extensively utilized in the stabilization of reaction injection molding (RIM) polyurethane and thermoplastic polyurethane (TPU) systems. Its compatibility with both aromatic and aliphatic polyurethane systems makes it versatile for manufacturing thermoplastic moldings, semi-rigid integral foams, and in-mold skins. The product is particularly effective in automotive interiors, protecting components such as instrument panels, steering wheels, window trim, headrests, and armrests from UV-induced degradation.

Beyond the automotive sector, this stabilizer finds significant application in synthetic leather coatings, tarpaulins, flooring solutions, sealants, and adhesives. It performs exceptionally well in both natural and colored materials, ensuring that aesthetic properties are preserved over the product lifecycle. Whether used in shoe soles or industrial coatings, UV-B75 delivers reliable performance against processing, light, and weather-induced stress.

Storage and Handling

To maintain optimal quality, UV Absorber UV-B75 should be stored in a cool, dry, and well-ventilated environment. Protection from moisture and excessive heat is essential during transportation and warehousing. The product exhibits good storage stability under recommended conditions. Users are advised to follow standard industrial safety protocols when handling chemical additives.
