Product Characteristics and Application:
The phosphorus content and antioxidant activity of this product is higher than common phosphite antioxidants (antioxidant activity of functional groups) . It is a kind of highly efficient phosphite antioxidant, it can make the polymer get effective protection under the condition of high temperature processing when adding Chic 626 , and also obtain good processing stability for many times.This product is a kind of highly efficient antioxidant, antioxidant activity of this product is better than the other phosphite, can make the polymer to obtain better processing stability when adding half of common phosphiteantioxidant .This product is generally not used alone, often blended with phenolic antioxidant such as antioxidant 1010 .This product compounded with phenolic antioxidants are widely used in PP, PE, PS, PA, PC, ABS and other polymer materials.General dosage is 0.1% - 0.3%.
Package and Storage:Fiber can (box) with aluminum foil bag , net weight is 25 kg per can (box).This product should be paid attention to moisture, heat.Valid for 6 months.
The information described in the technical performance and application methods are only reference for professionals, and not to use effect of the pledge. All new products and change the process, must make strict feasibility test, in order to best effect.
