The modern world relies heavily on polymers for an extensive range of applications, from everyday consumer goods to critical industrial components. However, many polymers are susceptible to degradation when exposed to ultraviolet (UV) radiation, a common component of sunlight. This photodegradation can manifest as yellowing, brittleness, cracking, and a significant loss of mechanical strength, ultimately limiting the useful lifespan of plastic products. To combat this, polymer manufacturers widely employ UV stabilizers, among which UV absorbers play a pivotal role.

UV absorbers function by absorbing harmful UV radiation and dissipating it as heat, thereby preventing it from initiating degradation processes within the polymer matrix. Among the most effective and widely used UV absorbers is UV Absorber UV-328 (CAS No. 25973-55-1). This benzotriazole derivative is renowned for its high efficiency in absorbing UV light, particularly in the 300-400 nm range, with a peak absorption at 345 nm. Its excellent compatibility with a broad spectrum of polymers, including polyolefins, styrenics, polyesters, and polyurethanes, makes it a versatile choice for formulators.

As a dedicated manufacturer and supplier of specialty chemicals, we are committed to providing polymer manufacturers with high-quality UV stabilizers that ensure product integrity and longevity. Our UV Absorber UV-328 boasts a purity of 99% or greater, low volatile matter (≤0.5%), and high thermal stability, making it suitable for processing at elevated temperatures. These properties contribute to its effectiveness in applications such as automotive parts, outdoor furniture, construction materials, and packaging, where resistance to weathering is crucial.

The benefits of incorporating UV Absorber UV-328 extend beyond mere UV protection. Its low volatility means less material loss during processing, leading to more efficient use and cost savings. Coupled with its excellent wash resistance, it ensures that the protection remains effective throughout the product's lifecycle. For polymer manufacturers looking to buy UV Absorber UV-328, understanding its application and dosage is key. Typically, concentrations range from 0.1% to 1.0% by weight, depending on the polymer type, product thickness, and expected UV exposure.
