Column chromatography silica gel supplier profile silicone p

Silicone pad is more common in our life, we are to have a meal, went to a restaurant, coffee shop etc. These places are often see the silicone pad, the silica gel pad what are the advantages? Make it widely recognized in the life.
 
Column chromatography silica gel supplier profile silicone pad what are the advantages
1, heat-resistant properties: silica gel pad product is silicon - oxygen key chain structure, the silicone mat product high thermal stability, high temperature silicone cake mold molecular bonds do not broken, do not break down. Silicone pad not only resistant to high temperature, and low temperature resistant, also can be used in a wide range of temperatures. Chemical properties and physical and mechanical properties, along with the change of temperature are small.
2, physiological inertia: polysiloxane compounds is one of the known inactive compounds. They are very resistant to biological aging, and the animal body without rejection, and has good anticoagulant capability.
 
3, electric insulation performance: silica gel pad product has good electrical insulating properties, the dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity of all came out on top in the insulation material, and their electrical performance is affected by temperature and frequency is small. Silicone pad, therefore, they are a kind of stable electric insulation material, is widely used in electronics, electrical industry. Organic silicon besides has excellent heat resistance, but also has excellent water repellency, this is using electrical equipment in wet conditions with high security.
 
4, low surface tension and low surface energy: silica gel mat product main chain is very smooth, the intermolecular force is much weaker than hydrocarbons, therefore, than with low molecular weight hydrocarbons viscosity, surface tension, surface energy is small, film forming ability. This kind of low surface tension and low surface energy is the main reason of column chromatography silica gel for various applications: hydrophobic, foam, foam stability, adhesion, lubrication, polishing, and other excellent performance.
