The raw material of silicone placemat is food-grade silicone, demoulding block speed, convenient production, durable, tasteless, insoluble in water and not easy to stick together with food, easy to clean, so it is popular, its specific properties are as follows:
1, silicone placemat temperature resistance characteristics: silicone placemat products are based on silicon-oxygen bond chain structure, silicone placemat products have high thermal stability, and the chemical bond of silicone cake mold molecules is not broken and not decomposed at high temperatures. Silicone placemats are not only resistant to high temperature, but also low temperature, and can be used in a wide temperature range. Both chemical properties and physical and mechanical properties change little with temperature.
2, silicone placemat physiological inertia: polysiloxane compounds are known to be one of the most inactive compounds. They are very resistant to biological aging, have no rejection reaction with animals, and have good anticoagulant properties.
3, silicone placemat electrical insulation properties: silicone placemat products have good electrical insulation properties, its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best insulating materials, and their electrical properties are very little affected by temperature and frequency. Therefore, they are a stable electrical insulation material, which is widely used in the electronic and electrical industry. In addition to heat resistance, silicone also has excellent water resistance, which is the electrical equipment used in wet conditions with high performance.
4, silicone placemat low surface tension and low surface energy: the main chain of silicone placemat products is very flexible, the intermolecular force is much weaker than hydrocarbons, therefore, than the same molecular weight of hydrocarbons low viscosity, weak surface tension, small surface energy, film forming ability. This low surface tension and low surface energy is the main reason for its many applications: hydrophobic, defoaming, foam stabilization, anti-sticking, lubrication, glazing and other excellent properties.
The above information is organized and released by the silicone placemat manufacturer - Kunshan Shuohong Electronics, welcome to call cooperation.
