There are significant differences between oil-emitting silicone and ordinary silicone rubber materials in many aspects. The following is a detailed comparison of the two materials:
1. Material and composition
Oil-emitting silicone: A special additive is added to the silicone coating, which allows it to emit a certain amount of oil during use. These grease-like substances give the oil-emitting silicone unique lubricating properties.
Ordinary silicone rubber: It is mainly made of silicone rubber base materials and does not contain the special additives in oil-emitting silicone, so it does not have the oil-emitting characteristics.
2. Performance characteristics
Oil-emitting silicone:
Lubricating properties: The grease-like substances that emerge on the surface provide excellent lubrication, reduce friction and reduce wear.
High temperature resistance: The operating temperature range is wide, and it can usually withstand high temperatures up to 300°C (the specific tolerance temperature may vary depending on the product).
Anti-stickiness: It is not easy to adhere to other substances, keeping the product clean and intact.
Corrosion resistance: It has good tolerance to corrosive substances such as acids and alkalis.
Ordinary silicone rubber:
High and low temperature resistance: It is still flexible at extremely low temperatures and can maintain stability at high temperatures, but the specific tolerance temperature range may be slightly narrower than that of oil-emitting silicone.
Chemical corrosion resistance: It has good tolerance to most chemical corrosion products such as acids and alkalis.
Insulation performance: It is an excellent insulating material that is not easy to conduct electricity.
Good flame retardancy: It is not easy to burn and is not easy to produce toxic smoke in a fire.
3. Application fields
Oil-emitting silicone: Due to its unique lubrication properties and high temperature resistance, anti-stickiness and other characteristics, it is widely used in machinery manufacturing, chemical industry, automobile manufacturing, medical equipment and food industry, especially in occasions requiring lubrication and sealing.
Ordinary silicone rubber: Due to its excellent high and low temperature resistance, chemical corrosion resistance, insulation and flame retardancy, it is widely used in the electronics industry, medical industry, automobile industry and home appliance industry.
4. Precautions for use
Oil-emitting silicone: When using, you need to pay attention to the control of oil output and ensure that the product has stable performance between different batches. At the same time, the surface should be kept dry and clean during construction to avoid oil volatilization affecting the use effect.
Ordinary silicone rubber: Although it is relatively simple to use, it is still necessary to select the appropriate model and specification according to the specific application requirements, and ensure that the construction conditions meet the product requirements.
In summary, there are significant differences between oil-bleeding silicone rubber and ordinary silicone rubber in terms of material, performance characteristics, application areas, and precautions for use. When choosing, comprehensive consideration should be given based on specific application requirements and conditions.
