Silica openings agent is a kind of amorphous silica, is a kind of efficient anti adhesion agent, opening agent, widely used in plastic masterbatch openings agent and functional masterbatch, plastic and PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride), used in PP masterbatch, the other can be used as EVA openings agent used for polyolefin IPP film, polyethylene LDPE film, BOPP two-way stretching polypropylene film efficient agent.

◆ Product Features:

1. The porous structure of silicon dioxide opening agent can effectively improve the phenomenon of "terminal yellowing". The porous structure of silicon dioxide absorbs metal ions, such as iron ions, making it less likely to cause yellowing due to oxidation.

2. Silicon dioxide opening agent has a greater bulk density, easier to mix with the resin, more convenient for processing and operation.

3. The addition of silicon dioxide opening agent in the film has a very small influence on the rise of haze, with high transparency, which effectively improves the phenomenon of "terminal yellowing".

◆ Recommended amount of addition: 1‰-1.5‰ is recommended during the film production process; It is recommended to add 25%-28% in the process of making open masterbatch
