What are the uses and properties of active (modified silica micro powder)?

Chinese names: Activated Silicon Micro Powder, Activated Quartz Powder; Modified silica micro powder, modified quartz powder English name: Kingsilica, surface treated Silica, activated Silica Technical indicators: SiO2 content 98-99.8%

Modified silica micro powder is mainly used as a functional filler for rubber and plastic; Artificial stone as the main material; Building structural adhesive filler; Epoxy resin casting filler; Electrical insulation fillers, casting materials for high, medium, and low voltage electrical components, etc. 

Modified silica micro powder is a non-toxic, odorless, and pollution-free hydrophobic (oleophilic) high-purity white micro powder, which 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 micro powder in polyolefin plastics does not reduce the MFR value, has good affinity, does not absorb water, and can enable ordinary plastic products to obtain better physical properties such as impact strength, stiffness, and improved cold and heat resistance.

Performance characteristics of modified silica 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 special engineering material;

2. Especially to ensure that polyolefin plastics reach or even exceed the impact strength of pure polyolefin plastics at room temperature under low temperature conditions, in order to prevent product rupture and loss caused by transportation, loading and unloading collisions, and accidental drops at low temperatures

3. Toughening, increasing rigidity, lowering freezing point temperature, and raising thermal deformation temperature by 10-15 ℃;

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