Clariant Hostavin® N 30 P is an oligomeric hindered amine light stabilizer. Different from traditional low-molecular-weight HALS, it has broad compatibility with plastic substrates and excellent migration resistance. Through multiple mechanisms such as free radical scavenging and peroxide decomposition, it provides long-lasting weathering protection for plastic products.
Oligomeric HALS molecular structure with excellent migration resistance and extraction resistance, ensuring long-lasting protective effect.
Good compatibility with various plastic substrates such as polyolefins and engineering plastics, without affecting the mechanical properties and transparency of products.
Multiple action mechanisms, capable of scavenging free radicals induced by UV light and decomposing hydroperoxides simultaneously, with high protection efficiency.
Excellent thermal stability, resistant to high-temperature environments of plastic processing, and not easy to decompose and fail during processing.
Synergistic effect can be achieved when compounded with UV absorbers, significantly improving the weathering grade of plastic products.
Suitable for polyolefin plastics (PE, PP), such as outdoor geomembranes, agricultural films and plastic pipes, extending outdoor service life.
Compatible with engineering plastics (PA, POM, PC), used for automotive exterior parts and electronic appliance housings to resist UV aging.
Applicable to PVC products, such as door and window profiles and outdoor fences, improving the anti-yellowing and anti-embrittlement ability of materials.
Used in thermoplastic elastomers (TPE) to provide weathering protection for outdoor seals and sports equipment.
Suitable for plastic alloy materials, ensuring long-term stability of appearance and performance of PC/ABS and other alloy products.
