Silicon Dioxide, E551, CAS no.7631-86-9, white powder. Silicon dioxide (SiO2), also known as silica, is a natural compound made of two of the earth's most abundant materials: silicon (Si) and oxygen (O2). Silicon Dioxide is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications used in silica gel, control moisture levels to avoid prevent certain goods from going bad. It is often used in cheese, fat spreads, confectionery, dried vegetables, etc. As an experienced Silicon Dioxide manufacturer and supplier, we has been supplying and exporting Silicon Dioxide for almost 10 years, please be assured to buy from us.

Description Silicone powder LYSI-100A is a powdered formulation with 55% ultra high molecular weight siloxane polymer and 45% silica . It is recommend to be used as processing aids in various thermoplastic formulations such as halogen free flame retardant wire&cable compounds , PVC compounds , engineering compounds, pipes, plastic/filler masterbatches..etc . Benefits (1) Improve processing properties including better flow ability , reduced extrusion die drool , less extruder torque , better molding filling & release (2) Improve surface quality like surface slip, lower Coefficient of friction, Greater abrasion & scratch resistance (3) Faster throughput , reduce product defect rate. (4) Enhance stability compare with traditional processing aid or lubricants (5) Slightly increase LOI and reduce heat release rate , smoke ,and carbon monoxide evolution Typical applications: For cable compounds, obvious improve processing properties and surface finish . For PVCfilm/sheet to improve surface smooth and processing properties. For PVC shoes sole , improve abrasion resistance . For PVC,PA, PC, PPS high temperature engineering plastics, can improve the flow of the resin and processing properties, promote the crystallization of PA, improve the surface smoothness and impact strength. . How to use Addition levels between 0.5~2.0% are recommended . Strongly suggest to pre-blend LYSI-100A and thermoplastic pellets prior to introduction to extrusion process . Package & Storage 20Kg / bag , craft paper bag ; Transport as non-hazardous chemical. Store in a cool , well ventilated place . Shelf life Original characteristics remain intact for 24 months from the production date , if kept in recommend st
