application:
It is a low temperature blowing agent. Decomposition products are colorless, non-toxic, odorless, and non-polluting; very slow decomposition; due to the low shrinkage of foam products and high tear strength, they are suitable for closed-cell plastics (such as sports shoes and closed-cell tapes) and foam sponges; Cannot be used with H blowing agent and aluminum salt agent. It can be used in PVC to obtain fine and uniform white foam products, but in some cases the surface of the mold needs to be plated with chrome. Excessive processing temperature (generally not exceeding 80°C) must be avoided to prevent premature foaming.

Packaging and storage:
25kg in cartons lined with polyethylene bags.
It should be stored in accordance with the provisions of Class 4.1 dangerous goods. The shelf life is 1 year.
