Application benefits

1. Applied to PP film, it can significantly improve the anti-blocking and smoothness of the film and avoid the adhesion during the film production. It can greatly reduce the dynamic and static friction coefficient of the film surface.

2. Under extremely harsh conditions such as high temperature, due to the particularity of polysiloxane structure, the film will keep a stable long-term smoothness.

3. It can improve the stripping performance of the release film, reduce the stripping force and reduce the stripping residue.

4. With ultra-high molecular weight polysiloxane as a smooth component, it can be wound with the matrix resin through a long molecular chain to achieve no precipitation, can effectively solve the "powder out" phenomenon of film products.

5. In the high temperature environment, it can still maintain a low friction coefficient, which can be applied to high-speed pack cigarette film that need to have good hot and smooth performance.

6. Due to the smoothing agent component contains silicone chain segments,  the product will have good processing lubricity, and can improve processing efficiency and also improve the production performance during the the production process. 

How to use

SF205 is especially suitable for polypropylene cast film and BOPP film. In order to provide good anti-blocking smoothening performance, it should be directly added to the surface layer of the film, and the recommended addition amount is 2~10%. The product only contains the smooth component and can be used independently with the anti-blocking agent.

Notes: The product has good processing performance, therefore, in the early processing it may clean out of leftover material or inpurity from the equipment, and result in the film crystal point increasing phenomenon, but after the production becomes stable, the film performance is not affected.
