What is the density of silicone products?


2020/8/6 11:44:41



The weight of silica gel product bai = product volume x silica gel density, which is the same as calculating the weight of water in mathematics.


The density of silica gel is generally around 1.02~1.03, and is generally calculated based on the density of 1.03. The density of silica gel and plastic are different, and the density of each material will be different.


Silica gel is a granular, glass, porous form of silica from the synthetic preparation of sodium silicate. Silicone dao glue is tough and hard; it's firmer than ordinary household gel like gelatin and agar. It is a naturally occurring mineral refined and processed into either granular or beaded form. As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules.

Features
High temperature resistance: applicable temperature range -40 to 230 degrees Celsius, can be used in microwave and oven.
Easy to clean: The silicone products produced by silica gel can be cleaned after being rinsed in clean water, and can also be cleaned in the dishwasher.
Long life: The chemical properties of silica gel are very stable, and the products made have a longer life than other materials.
Soft and comfortable: Thanks to the softness of the silicone material, the cake mold products are comfortable to the touch, very flexible and not deformed.
Variety of colors: According to the needs of customers, different beautiful colors can be deployed.
Environmental protection and non-toxic: no toxic and hazardous substances are produced from the raw materials entering the factory to the finished product shipment.
Electrical insulation performance: Silicone rubber has a high resistivity, and its resistance can remain stable in a wide temperature range and frequency range. At the same time, silica gel has good resistance to high-voltage corona discharge and arc discharge, such as high-voltage insulators, high-voltage caps for TV sets, and electrical components.
Low temperature resistance: ordinary rubber has a minimum temperature critical point of -20°C to -30°C, but silicone rubber still has good elasticity from -60°C to -70°C, and some specially formulated silicone rubber can withstand Very low temperature, such as low temperature sealing ring, etc.
Conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has good conductivity, such as keyboard conductive contact points, heating element parts, antistatic parts, high-voltage cable shields, medical physiotherapy conductive films, etc.
Weather resistance: Ordinary rubber is rapidly degraded under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone, and its physical properties have only minor changes under ultraviolet light and other weather conditions for a long time, such as outdoor use Sealing materials, etc.
Thermal conductivity: When certain thermal conductive fillers are added, silicone rubber has good thermal conductivity, such as heat sinks, thermally conductive gaskets, photocopiers, fax machine thermal rollers, etc.
Radiation resistance: The radiation resistance of silicone rubber containing phenyl groups is greatly improved, such as electrically insulated cables and connectors for nuclear power plants.
