Selecting the appropriate UV stabilizer is critical for protecting polymers from photodegradation, especially in applications exposed to prolonged sunlight. This guide, presented by NINGBO INNO PHARMCHEM CO.,LTD., a prominent chemical supplier, delves into the benefits and applications of Benzoxazinone UV Absorber 3638, a product renowned for its high efficiency and unique properties. For R&D scientists and procurement managers aiming to purchase superior UV protection solutions, understanding its capabilities is key.

The Science Behind UV Absorber 3638

UV Absorber 3638 belongs to the benzoxazinone class, a group of highly effective UV absorbers. Its primary function is to absorb harmful UV radiation, converting it into harmless thermal energy, thereby preventing damage to the polymer matrix. What sets UV Absorber 3638 apart is its exceptionally strong absorption profile across the entire UVA and UVB spectrum, combined with its negligible contribution to initial polymer color. This characteristic is invaluable for clear plastics, films, and coatings where maintaining transparency is a priority.

For product formulators and engineers, the processing parameters of additives are as important as their protective functions. UV Absorber 3638 excels with its high thermal stability, maintaining its structure and efficacy at temperatures exceeding 300°C. This makes it a prime candidate for injection molding and extrusion processes involving engineering plastics like PET, PC, PBT, and PPO. As a dedicated manufacturer, we ensure consistent product quality when you buy from us.

Application Focus: Engineering Plastics and Beyond

The high thermal resistance and low volatility of UV Absorber 3638 make it an excellent choice for demanding applications. It is particularly favored in the production of PET films and containers, polycarbonate sheets, and other plastics requiring long-term UV stability. Its efficacy also extends to polyamides, polyacetals, and styrenics, providing robust protection against weathering. Companies looking to buy a versatile and reliable UV stabilizer will find UV Absorber 3638 a compelling option. Its ability to protect materials even during recycling processes adds to its economic and environmental value.
