In the realm of material science, understanding the precise properties of chemical additives is fundamental for achieving optimal product performance. UV Absorber 3638 (CAS 18600-59-4) is a prime example of a highly specialized additive that plays a critical role in protecting polymers and coatings from the damaging effects of UV radiation. NINGBO INNO PHARMCHEM CO.,LTD, as a leading supplier of fine chemical intermediates, is dedicated to educating its B2B clientele—including R&D scientists and product formulators—about the advantages and applications of such essential compounds.

UV Absorber 3638, a benzoxazinone-type UV absorber, is characterized by its robust performance profile. Its chemical structure allows for strong and broad UV absorption, particularly in the 300-360 nm range, effectively shielding materials from photodegradation. Crucially for many applications, it exhibits virtually no color contribution, making it ideal for use in clear or lightly colored formulations where aesthetic integrity is paramount. The low volatility of this product is another significant advantage, especially for polymers processed at high temperatures, such as PET, PBT, and PC. This ensures that the UV absorber remains in the polymer matrix, providing lasting protection.

The applications for UV Absorber 3638 are diverse and span across various industries. It is widely adopted in engineering plastics, including PET, PBT, PC, Nylon, PPO, and PPS, to enhance their weatherability and extend their service life, whether for indoor or outdoor use. This makes it a valuable purchase for manufacturers of automotive components, construction materials, electronic housings, and more. Procurement managers seeking reliable plastic auxiliary agents will find that UV Absorber 3638 offers excellent stabilization properties, contributing to product durability and customer satisfaction.

For those looking to buy UV Absorber 3638, understanding its specifications is key. Typical purity levels are 98% or higher, with low ash content and minimal loss on drying, ensuring consistent performance. The compound's compatibility with various polymers and its effectiveness when used alone or in synergistic blends with antioxidants and other light stabilizers further underscore its versatility.
