In the world of polymer formulation, selecting the right additives is key to achieving desired product performance and longevity. Among the most critical are UV stabilizers, which protect materials from the damaging effects of ultraviolet radiation. This guide focuses on UV Absorber 328, a highly effective solution that many formulators rely on. As a dedicated supplier and manufacturer, we aim to provide you with the insights needed to make informed decisions about your polymer protection needs.

UV Absorber 328 is a benzotriazole-class UV absorber known for its robust performance characteristics. It offers excellent UV absorption in the 270-340 nm range, which is crucial for preventing phot degradation in many common polymers. Its benefits include good compatibility with a wide range of resins, such as polyolefins (especially polyethylene), polyesters, styrene polymers, polyamides, polycarbonates, and elastomers. Furthermore, its low volatility ensures it remains within the polymer matrix during high-temperature processing and throughout the product's service life, while its high wash resistance is beneficial in applications where contact with liquids is expected.

When considering which UV stabilizer to purchase, formulators often look for a balance of performance, cost, and ease of integration. UV Absorber 328 strikes a favorable balance. Its effectiveness in preventing color changes, loss of mechanical properties, and surface chalking makes it a cost-effective solution for enhancing product durability. Its broad applicability means it can serve multiple product lines, simplifying procurement and inventory management. As a reliable manufacturer in China, we ensure a consistent supply of high-purity UV Absorber 328, supporting your production schedules.

The typical applications for UV Absorber 328 span numerous industries. It is essential for automotive coatings, preventing fade and degradation of clear coats and painted surfaces. In the building and construction sector, it protects window profiles, roofing membranes, and siding from weathering. For packaging, it shields sensitive contents from UV light.
