Since , Fournier Rubber & Supply Company has offered top-quality high-temperature gaskets, helping customers identify applications that demand this type of specialized product.
A heat-resistant gasket can withstand extreme operating temperatures, ranging between 350ºF (177ºC) and ºF (ºC). The high-temperature material used to construct these gaskets delivers seals with superior reliability, far outreaching the capabilities of materials used to manufacture traditional gaskets.
Seals and gaskets constructed using high-temperature materials can perform well in applications that involve variable heat sources, such as:
When using standard silicone rubber for manufacturing high-temperature sealing gaskets, the durable material can easily handle temperatures as high as 475ºF (246ºC). Special-grade silicone rubber is mandatory for all applications requiring higher temperature, fire, or thermal resistance.
Using industrial high-temperature gasket material offers a wide range of benefits, such as:
Over time, a high-temperature gasket proves to be a valuable investment. The material used to manufacture heat-resistant gaskets can withstand intense thermal conditions and, depending on the operating environment, can last much longer than traditional gaskets.
Using heat-resistant gaskets on components that come in contact with high temperatures can provide durability to the overall project. Available in a broad range of materials, high heat-resistant gas gaskets can be manufactured using PTFE (Teflon), graphite, natural rubber, and more. Each material offers distinct advantages for temperatures and specific working conditions.
If a gasket cannot withstand the extreme heat of an application, the entire operation could fail. Gaskets keep two components separate from one another, and if that function fails, it could prove harmful to the manufacturing process. A domino effect can begin when containment is breached, weighing down production.
Using a heat-resistant gasket that can withstand high temperatures will enable performance at optimal capacity, keeping operations running efficiently.
Heat-resistant gaskets provide several options for use in a wide variety of applications, depending on their characteristics and temperature-resistant properties. Whether a project has limited exposure to a lot of heat or encounters extreme temperatures continuously, a heat-resistant gasket can prove beneficial in both cases.
The most common cause of containment failure is the degradation of gasket material and adhesives that cannot tolerate extreme heat exposure. Selecting a high-temperature gasket sealant with the required heat resistance properties prevents the product from degrading too rapidly.
Fournier Rubber & Supply Company offers premium sponge and solid rubber materials suitable for high-heat applications. In regards to elastomeric properties, the following materials are among the best high-temperature performers, with each providing a specific operating range that includes:
This material plays an essential role where fluoroelastomers are required, providing a practical low hardness limit of 55 durometers. The material fills a void where softer material is needed but still demands resistance to heat and other fluids
A silicone sponge protects or seals various outdoor lighting, electronic, or communication enclosures while offering improved sealing and durability. The material has a higher tear and tensile strength than lower-grade sponge materials, with a UL-94VO rating. Silicone sponge protects against fire, wind-driven rain, and small dust particles.
The high-performance rubber material is an ideal solution for containing fluids that traditionally lead to the rapid degradation of regular elastomers.
Sealing against exhaust and steam emissions and other high-temperature media requires a rigid, durable material that can withstand thermal degradation over fluctuating operating conditions. Non-asbestos fiber and mica gaskets prove beneficial, especially where oxygen exists and standard materials, such as graphite, would fail. Examples of these applications include the following:
High-temperature gasket seals can efficiently withstand the demands of thermal applications. The rubber compound can handle applications that involve combustible materials or flames and solids, gasses, or liquids at extreme temperatures. The material used to manufacture high-temperature gaskets provides reliable sealing beyond the scope of standard gasket material performance.
Common applications requiring heat-resistant gaskets include the manufacture and processing of hot oils, saturated steam, engine operation, waste gas, and more. These applications demand high-temperature gaskets that can withstand intense temperatures and heat that often exceeds 500ºF (260ºC).
Fournier Rubber & Supply Company offers a wide variety of top-quality, heat-resistant gaskets suitable for use in a broad range of industries and applications. We construct our products of the highest-grade material in the industry and can meet the demands of most applications.
Nitrile rubber oil seal, also known as Nitrile rubber oil seal, is a common sealing material widely used in various engineering and mechanical applications. This article will introduce the advantages and disadvantages of nitrile rubber oil seals to help you better understand its characteristics and applications.
advantage:
The company is the world’s best high temperature oil seal supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Outstanding oil resistance:
Nitrile rubber oil seals have excellent oil resistance and are suitable for various lubricating oil and fuel environments. It can effectively prevent oil leakage and extend the life of mechanical equipment.
Good elasticity:
Nitrile rubber has high elasticity and can effectively adapt to irregular sealing surfaces to ensure good sealing results.
Cost-effectiveness:
Nitrile rubber is a relatively inexpensive sealing material, making it cost-effective in a variety of applications. It provides reliable sealing performance without putting an undue strain on the budget.
Easy to process and customize:
Nitrile rubber is easy to process and can be customized to meet the needs of different applications. Whether it is size, shape or hardness, it can be flexibly adjusted.
Commonness and availability:
Nitrile rubber is a widely used sealing material that is easily available and commonly available in the market and can be obtained in a short time.
shortcoming:
Limited high temperature resistance:
Nitrile rubber has poor performance in high temperature environments and is prone to softening and loss of elasticity. Therefore, nitrile rubber oil seals are not suitable for use in high temperature applications.
Not resistant to ozone and UV rays:
Nitrile rubber is sensitive to ozone and UV rays and prone to aging and cracking, making it unsuitable for use in outdoor exposure environments.
Limited chemical resistance:
While nitrile rubber has good resistance to many lubricants and fuels, it has limited resistance to certain chemicals. In certain chemical environments, other sealing materials may need to be considered.
Not suitable for high viscosity liquids:
Nitrile rubber oil seals may encounter some problems in applications with high viscosity liquids because it may not be elastic enough to effectively seal these liquids.
In summary, nitrile rubber oil seals have many advantages, including oil resistance, elasticity, cost-effectiveness, etc., making them widely used in a variety of applications. However, it also has some limitations, such as not resistant to high temperatures, not suitable for high-viscosity liquids, and not resistant to ozone. Therefore, when selecting sealing materials, trade-offs need to be made based on the requirements and environment of the specific application.
