FEATURE AND APPLICATION


Provides antioxidant activity both during thermal processing and in moderate elevated temperatures due to radical scavenging mechanism.
Exhibits excellent compatibility, low color contribution, low volatility and low toxicity.
Is an excellent ultraviolet light stabilizer for olefins, particularly pigmented opaque formulations, for applications such as pipes, drums, sheeting, marine, and garden.
Can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use - synergizies well with UV absorbers and antioxidants which function as hydroperoxide decomposers.
Store in a cool, dry, ventilated place; avoid direct sunlight.
For more information, please refer to the safety technical specification, light stabilizer 2908 through the free radical capture mechanism, in the hot processing process and mild heating process has antioxidant activity, can effectively protect the polymer; and showed excellent compatibility, low color change, low volatile, low toxicity.

And our ultraviolet absorbent 2908 is a special ultraviolet absorbent for olefins, especially suitable for colored opaque products, such as pipes, plastic buckets, sheets, ships and horticultural products. It can be used with phenols, phosphite antioxidants and hindered amine series light stabilizers to improve outdoor weather resistance. The product can effectively eliminate hydroperoxide in polymer and has good synergistic effect with ultraviolet absorbent and antioxidant.

The above two UV absorbers have good results in all aspects of performance, the above two are now in stock, welcome to consult our sales staff.
