Silicone Washers vs Rubber Washers: Which One is Better?
Washers are small but essential components that are used to prevent leaks, distribute pressure, and protect surfaces from damage. They are usually made of non-metallic materials, such as rubber, silicone, plastic, or felt. However, not all washers are created equal. Depending on the application and the environment, some washers may perform better than others.
One of the common questions that many people have is whether silicone washers are better than rubber washers. The answer is not straightforward, as both types of washers have their own advantages and disadvantages. In this article, we will compare silicone washers and rubber washers in terms of their properties, uses, and benefits.
What are silicone washers?
Silicone washers are washers made of silicone rubber, which is a synthetic elastomer that consists of silicone and oxygen atoms. Silicone rubber has many desirable characteristics, such as:
- High temperature resistance: Silicone rubber can withstand temperatures ranging from -60°C to 230°C without losing its elasticity or strength.
- Chemical resistance: Silicone rubber can resist various chemicals, such as oils, solvents, acids, and alkalis.
- Weather resistance: Silicone rubber can resist the effects of sunlight, ozone, moisture, and oxidation.
- Electrical insulation: Silicone rubber can prevent electric currents from passing through it.
- Biocompatibility: Silicone rubber is non-toxic and does not cause allergic reactions or irritations.
Silicone washers are typically used in applications that require high performance and durability, such as:
- Automotive: Silicone washers can be used for sealing engine parts, hoses, valves, and pumps that are exposed to high temperatures and pressures.
- Medical: Silicone washers can be used for sealing medical devices, implants, catheters, and tubes that are in contact with bodily fluids and tissues.
- Food and beverage: Silicone washers can be used for sealing food processing equipment, containers, and utensils that are exposed to high temperatures and hygiene standards.
- Electronics: Silicone washers can be used for sealing electrical components, connectors, switches, and circuits that are exposed to high voltages and currents.
