Hostavin® N 845 PP

2,2,6,6 - Tetramethyl piperidine. It acts as a hindered amine light stabilizers (HALS). It does not absorb UV light, and their protective action in polymers is usually attributed to scavenging of propagating radicals. It's chemical structure offers an optimal balance of physical and chemical properties with lower fogging and less VOC (volatile organic compounds). It is very effective especially in stabilization of polyolefins (PP, LDPE, HDPE, LLDPE) and provides a good compatibility with non-polar polymer matrices with a high resistance to extraction by water or by detergent solutions. It used for flexible PVC and is applicable for the stabilization of compression molded, injection molded, and extruded plastic articles. It has an automotive application also for e.g. interior and exterior automotive parts (e.g. dashboards, car sidings, bumpers), garden furniture, etc.
