Product Detail

Product Tags


CAS Number: 42774-15-2
Chemical Name: N, N'-Bis(2, 2, 6, 6-tetramethyl-4-piperidinyl)-1, 3-b enzenedicarboxamide
Structure: H3391 is a novel Multi-functional additive of HALS for polyamides which combines several beneficial properties in one single molecule.


Suggested Applications

Due to its unique molecular structure, H3391 acts as a stabilizer of melt or as a melt process modifier. This effect is manifested by high stabilizer of polyamide melt pressure which leads to higher quality of injection and blow-molded or extruded PA articles, as well as lower rate of filament breaks during fiber spinning.
