BX Silicon K70 Anti-blocking agent

Introduction

Bx silicon K70 plastic grade silica is a kind of amorphous silica synthesized by precipitation method. It looks like white powder. It is manufactured through special processing technology and has good compatibility with plastics. It has a porous structure, which results in less addition, good dispersion, no need for grinding, and will not affect the transparency and strength of the plastic film. Non-toxic, non-polluting, does not contain any volatile substances and precipitates, ensuring the quality of the packaged items; improves the adhesion resistance of the film on high-speed packaging lines, improves creep resistance, and has a reinforcing effect on the film; this particle The exposed molecular chains of the polymer are reduced during the processing, so that there is no entanglement of macromolecular chains when the two films are in contact, thereby solving the anti-blocking problem; at the same time, because the molecular chains are not exposed, the film also reduces friction when it is rubbed by objects. adsorption force, thus increasing slipperiness.

Product purpose and usage:

This product is mainly used for PP, PE, PET, and PVC plastic film masterbatch to improve the anti-blocking performance and film slipperiness of the film without grinding. For PET film customers with extremely low moisture requirements, the product can be dried below 300°C before use without affecting the performance of the product. Replace Grace SYLOBLOC & PQ Gasil AB series gas silicon.
