EPDM (Ethylene Propylene Diene Monomer) rubber is highly regarded for weatherstripping due to its excellent resistance to environmental factors. Compared to other types of rubber, EPDM offers superior resistance to UV rays, ozone, and extreme weather conditions, making it ideal for outdoor applications. It maintains flexibility and durability over a wide temperature range, from -40°C to 150°C, which is crucial for weatherstripping that must endure seasonal temperature fluctuations. Unlike natural rubber, which can degrade quickly when exposed to sunlight and ozone, EPDM retains its properties, ensuring a longer lifespan. It also outperforms SBR (Styrene-Butadiene Rubber) in terms of weather resistance, although SBR is often used for its cost-effectiveness in less demanding environments. EPDM's chemical structure provides excellent resistance to water, steam, and polar substances, but it is not suitable for applications involving petroleum-based oils and fuels, where nitrile rubber would be preferable. Compared to silicone rubber, EPDM is more cost-effective and provides adequate performance for most weatherstripping needs, although silicone offers better high-temperature resistance and flexibility at low temperatures. In terms of installation, EPDM is easy to work with and can be molded or extruded into various shapes and sizes, making it versatile for different weatherstripping applications. Its ability to form a tight seal helps in energy conservation by preventing air and water leaks. Overall, EPDM rubber is a top choice for weatherstripping due to its balance of durability, weather resistance, and cost-effectiveness, outperforming many other rubber types in outdoor and harsh environmental conditions.

Viton rubber, a brand of fluoroelastomer, is highly regarded in chemical processing applications due to its exceptional resistance to a wide range of chemicals, high temperatures, and environmental conditions. It performs well in environments where other elastomers might degrade, making it a preferred choice for seals, gaskets, and hoses in the chemical industry. Viton's chemical resistance is one of its most significant advantages. It can withstand exposure to a variety of aggressive chemicals, including acids, alkalis, oils, fuels, and solvents. This makes it suitable for use in applications involving harsh chemicals and aggressive media. Its resistance to swelling and degradation in such environments ensures long-term performance and reliability. In terms of temperature resistance, Viton can operate effectively in a broad temperature range, typically from -20°C to 200°C (-4°F to 392°F), with some grades capable of withstanding even higher temperatures. This makes it ideal for high-temperature applications, such as those found in chemical processing plants where thermal stability is crucial. Viton also exhibits excellent resistance to ozone, weathering, and UV radiation, which is beneficial for outdoor applications or those exposed to environmental elements. Its low permeability to gases and vapors further enhances its suitability for sealing applications in chemical processing. However, Viton is not without limitations. It is generally more expensive than other elastomers, and its performance can be compromised in the presence of certain chemicals, such as ketones, amines, and organic acids. Despite these limitations, its overall performance in chemical processing applications is highly valued, making it a reliable choice for demanding environments.

Silicone rubber is known for its exceptional temperature tolerance, making it a versatile material for various applications. It can typically withstand temperatures ranging from -60°C to 230°C (-76°F to 446°F). Some specialized formulations can endure even more extreme conditions, with lower limits reaching -100°C (-148°F) and upper limits extending to 300°C (572°F) for short periods. At low temperatures, silicone rubber maintains its flexibility and elasticity, unlike many other materials that become brittle. This property makes it suitable for applications in cold environments, such as gaskets and seals in refrigeration systems. At high temperatures, silicone rubber retains its mechanical properties and resists degradation better than many other elastomers. It does not melt or become brittle, which is why it is often used in automotive, aerospace, and industrial applications where heat resistance is crucial. Silicone rubber's ability to withstand high temperatures also makes it ideal for use in cookware, bakeware, and other kitchen utensils. However, prolonged exposure to temperatures near the upper limit can lead to gradual degradation, including hardening and loss of elasticity. To enhance performance, additives and fillers can be incorporated into silicone rubber formulations, improving its thermal stability and extending its service life under extreme conditions. Overall, silicone rubber's wide temperature tolerance, combined with its chemical resistance, electrical insulating properties, and biocompatibility, makes it a preferred choice for a broad range of applications across different industries.

Polyurethane rubber generally exhibits higher tensile strength compared to many other types of rubber. It typically ranges from 2,000 to 6,000 psi, which is significantly higher than natural rubber, which usually has a tensile strength of about 2,500 to 3,500 psi. This makes polyurethane rubber particularly suitable for applications requiring durability and resistance to wear and tear. Compared to silicone rubber, which has a tensile strength of around 1,200 to 1,500 psi, polyurethane is much stronger. Silicone is often chosen for its thermal stability and flexibility rather than its tensile strength. Neoprene rubber, another common type, has a tensile strength of approximately 900 to 1,500 psi, which is also lower than that of polyurethane. Nitrile rubber, known for its oil resistance, has a tensile strength ranging from 1,500 to 3,000 psi, which can be comparable to the lower end of polyurethane's range but generally does not match its upper limits. EPDM rubber, used for its weather resistance, has a tensile strength of about 1,500 to 3,000 psi, again falling short of polyurethane's capabilities. Viton, a type of fluoroelastomer, has a tensile strength of about 1,500 to 2,000 psi, which is lower than polyurethane. However, Viton is often selected for its chemical resistance rather than tensile strength. Overall, polyurethane rubber's superior tensile strength, combined with its excellent abrasion resistance and load-bearing capacity, makes it a preferred choice for demanding industrial applications, such as in the manufacturing of seals, gaskets, and wheels, where mechanical stress is a significant factor.
