Frequently Asked Questions
Q
What is UV 3529 and what type of stabilizer is it?
A
UV 3529 is a high-performance, high-molecular-weight hindered amine light stabilizer (HALS). Its CAS number is 193098-40-7. It is designed to protect polymer materials from UV-induced degradation, featuring minimal color contribution, extremely low volatility, and low alkalinity.
Q
What is the physical form and appearance of UV 3529?
A
UV 3529 is supplied as a light yellow or off-white powder, making it easy to blend into various polymer processing systems.
Q
What are the key technical specifications of UV 3529?
A
The key specifications include: Melting Point between 95.00–120.00 ℃, Drying Loss ≤ 0.5%, and Glass Transition Temperature ≥ 88 ℃. These properties ensure stability and consistent performance during processing and end-use.
Q
Which polymer substrates is UV 3529 suitable for?
A
UV 3529 is suitable for a broad range of polymer materials, including PE and PP agricultural films, artificial turf, injection molding and rotational molding products, PP fibers, POM, PA, PET, PBT, ASA, ABS, HIPS, flexible and rigid PVC, PMMA, and PUR substrates.
Q
Why is UV 3529 preferred for long-term outdoor applications?
A
UV 3529's macromolecular structure significantly enhances migration resistance, meaning the stabilizer remains in the polymer matrix over extended periods. Combined with its extremely low volatility and minimal color contribution, it provides durable UV protection ideal for outdoor-exposed products such as agricultural films and artificial turf.
Q
What is the significance of low alkalinity in UV 3529?
A
Low alkalinity in UV 3529 is important because it reduces the risk of interference with acid-sensitive additives such as certain flame retardants and catalysts used in polymer processing. This makes UV 3529 more compatible with a wider range of formulations compared to conventional HALS products.
