Frequently Asked Questions
Q
What is UV 3529 and what type of stabilizer is it?
UV 3529 is a high-performance, high-molecular-weight hindered amine light stabilizer (HALS) with the CAS number 193098-40-7. It is designed to provide long-term protection against UV-induced degradation in a wide range of polymer materials.
Q
What are the key performance advantages of UV 3529?
UV 3529 offers minimal color contribution, extremely low volatility, and low alkalinity. Its macromolecular structure provides excellent migration resistance, making it especially suitable for demanding long-term outdoor applications.
Q
Which polymer materials is UV 3529 compatible with?
UV 3529 is compatible with a broad range of polymers including PE, PP, POM, PA, PET, PBT, ASA, ABS, HIPS, flexible and rigid PVC, PMMA, and PUR. It is also suitable for PP fibers and agricultural film applications.
Q
What is the physical form and appearance of UV 3529?
UV 3529 is supplied as a light yellow or off-white powder. Its melting point ranges from 95.00 to 120.00 ℃, with a glass transition temperature of ≥ 88 ℃ and a drying loss of ≤ 0.5%.
Q
Is UV 3529 suitable for agricultural film and outdoor applications?
Yes. UV 3529 is specifically recommended for PE and PP agricultural films and artificial turf, as well as injection molding and rotational molding products that require durable outdoor UV protection over extended periods.
Q
Why is the high molecular weight of UV 3529 important?
The high molecular weight of UV 3529 significantly reduces its tendency to migrate out of the polymer matrix during processing or end-use. This ensures consistent and long-lasting stabilization performance, particularly in applications exposed to heat, moisture, or prolonged UV radiation.
