When it comes to sealing, having the right materials is essential. Sealing is a critical component for protecting applications from environmental factors such as water, dust, and other harmful elements that can cause damage or affect performance.

Traditional sealing materials such as rubber and silicone have been used for a long time, but today technological advancements have led to the creation of revolutionary sealing materials that offer superior performance. In this article, we will explore these materials and their unique advantages.

1. Liquid Silicon Rubber (LSR)

LSR is a popular type of silicone rubber with a low viscosity that makes it ideal for molding and injection processes. It is a unique material that can resist high and low temperatures without requiring additional reinforcement.

LSR also displays excellent resistance to UV light, ozone, and chemical exposure. These properties make it an excellent choice for applications such as automotive, electronics, and healthcare equipment. LSR is also biocompatible and hence widely used in the medical industry for sealing implantable devices.

2. Fluorosilicone Rubber (FSR)

Fluorosilicone rubber is a synthetic rubber that has a combination of properties that make it desirable for sealing applications. FSR has excellent chemical and fuel resistance and can withstand high temperatures.

Additionally, FSR is known for its low gas permeability which makes it ideal for use in aerospace and oil and gas industries. FSR is also resistant to oxidation and ozone, making it ideal for outdoor applications.

3. Ethylene Propylene Diene Monomer (EPDM)

EPDM is a durable synthetic material that can resist extreme temperatures, weathering, ozone, and UV light exposure.

It is used extensively in the roofing industry, automotive, and construction as it can provide an excellent seal for applications exposed to the elements. EPDM is also resistant to acids, alkalis, and oxygenated solvents which makes it an excellent choice for chemical processing applications.

4. Polyurethane (PU)

Polyurethane is a synthetic material that is highly resistant to abrasion and chemical exposure. It can withstand high and low temperatures and is commonly used to seal against water, dust, and chemicals.

PU foam is also used as a sealing material in the construction industry as it can expand and fill cavities, providing an excellent seal. Polyurethane is also resistant to oils, solvents, and oxidizing agents, making it ideal for use in the automotive industry.

5. Perfluoroelastomer (FFKM)

FFKM is a high-performance elastomer that is highly resistant to a wide range of chemicals, heat, and pressure. It can withstand temperatures of up to 327°C and can resist almost all chemicals apart from molten alkali metals and fluorine gas.

FFKM is commonly used in industries such as aerospace, semiconductor manufacturing, and chemical processing due to its superior sealing capabilities in harsh environments.

6. Thermoplastic Elastomers (TPE)

TPE is a versatile material that combines the properties of rubber and plastic. It is easy to process and can be molded into various shapes to fit complex sealing requirements.

TPE also provides excellent elasticity, tensile strength, and tear resistance, making it ideal for applications where sealing movement is expected. Additionally, TPE is resistant to wear and tear, UV exposure, and aging, making it ideal for outdoor applications.

7. Polytetrafluoroethylene (PTFE)

PTFE is a high-performance synthetic polymer with excellent resistance to high temperatures, chemicals, and wear. It is used commonly in applications where a highly durable and non-stick seal is required, such as food and medical processing.

PTFE is also non-toxic, making it ideal for applications where contact with food and drugs is necessary.

8. Neoprene

Neoprene is a synthetic rubber with excellent oil and chemical resistance. It is used in applications such as automotive, marine, and industrial sealing due to its excellent resistance to weathering, ozone, and heat.

Neoprene is easy to process and can be molded into various shapes, making it ideal for complex sealing requirements.

9. Butyl Rubber

Butyl rubber is a synthetic rubber that has excellent gas and moisture resistance. It is commonly used in the automotive and construction industries as a sealant for roofs, windows, and doors.

Butyl rubber can withstand high and low temperatures and offers excellent resistance to ozone, UV light, and chemicals.

10. Silicone Foam

Silicone foam is a high-performance material that can provide an excellent seal against water, dust, and other environmental factors.

It is used commonly in applications such as automotive, aerospace, and electronics due to its excellent resistance to extreme temperatures. Silicone foam also displays excellent chemical resistance, making it ideal for chemical processing applications.

Conclusion

Choosing the right sealing material is essential for ensuring the longevity and performance of critical equipment and devices.

These ten revolutionary materials offer superior sealing capabilities and perform exceptionally well in challenging environments. By understanding the unique properties and advantages of each of these materials, industries can select the right material to deliver superior performance.
