Chinese name: active silicon powder, active quartz powder; Modified silica powder, modified quartz powder English name: Kingsilica, surface treated silica, activated silica Technical indicators: SiO2 content 98-99.8% Modified silica powder Main use: rubber, plastic functional fillers; Artificial stone main material; Building structural adhesive filler; Epoxy resin casting filler; Electrician insulation filler, casting materials for high, medium and low voltage electrical parts, etc. Modified silicon micropowder is a non-toxic, odorless, and pollution-free high-purity white micropowder with hydrophobicity (lipophilicity). It has excellent properties such as good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness. The use of modified silica powder in polyolefin plastics does not reduce the MFR value, has good affinity, does not absorb water, and can enable ordinary plastic products to achieve good impact strength, stiffness, and improve physical properties such as cold and heat resistance.

Activated (modified) silica micropowder

Performance characteristics of modified silicon micro powder:

1. Make the old material reach the impact strength of the new material and the new material reach the impact strength of the specialized engineering material;

2. Especially to ensure that the impact strength of polyolefin plastic reaches or even exceeds that of pure polyolefin plastic at room temperature under low temperature

conditions, to prevent product damage caused by transportation, loading and unloading collisions, and accidental drops at low temperatures

3. Toughening, stiffening, reducing freezing point temperature, and increasing thermal deformation temperature by 10-15 ℃;

4. Greatly reduce the cost of product raw materials; 5. Extend the service life of the product;
