Tiangang® HS-625

Oligomeric Methylated Hindered Amine light stabilizer (HALS)

Chemical Name Hindered amine derivative
Tiangang® HS-625 is a novel patented oligomeric methylated hindered amine light stabilizer (Me-HALS), featuring high molecular weight, and lower interactions with acidic substances. It is particularly suitable for use in thin polyolefin applications. It also serves as long-term heat stabilizer. It offers superior performance compared to other state-of-the-art methylated HALS such as 119 and 3346, in that it features higher molecular weight, and higher effective nitrogen content, which translates into higher performances in thin applications such as films and fibers. It also offers much better protection in terms of long-term heat stability. This product is fully cleared for REACH and TSCA. FDA is being registered. It offers particularly good performances when used in combination with benzotriazole and triazine types of UV Absorbers.
