Description	Tiangang^® HS-962 is a synergistic mixture of Tiangang^® BW-10LD and Tiangang^® HS-944. It is a highly effective radical scavenger belonging to the Hindered Amine Light Stabilizers (HALS) family of stabilizers. It is a versatile UV stabilizer with outstanding extraction resistance, low fading and low pigment interaction, and particularly well suited for LDPE, LLDPE, HDPE films, tapes and thick sections and for PP in fibers and films. It is also the product of choice for thick sections where indirect food contact approval is required.
