What's better than neoprene?

While neoprene is a versatile material, other rubbers like EPDM (Ethylene Propylene Diene Monomer) can offer better resistance to certain conditions, such as ozone and UV exposure. What is EPDM rubber?¹

EPDM offers superior resistance to UV and ozone, making it an excellent alternative to neoprene in specific applications.

Neoprene is a widely used synthetic rubber known for its resistance to oils, chemicals, and weathering, but it has limitations, particularly in its performance under prolonged exposure to UV light and ozone. In contrast, EPDM rubber performs exceptionally well in harsh outdoor environments due to its excellent resistance to UV radiation, ozone, and weathering. If your application involves outdoor exposure or extreme weather conditions, EPDM may be a better choice than neoprene.

What is the cheapest type of rubber?

SBR (Styrene-Butadiene Rubber) and Natural Rubber (NR) are typically the cheapest options among all types of rubber. SBR offers good abrasion resistance and impact strength, making it a low-cost synthetic alternative. Compared to some other synthetic rubbers, natural rubber often has a cost advantage. Very affordable options can be found for specific applications. It is made from latex extracted from rubber trees and is used in a variety of everyday applications. What are the uses of natural rubber?²

SBR and Natural rubber are the most affordable types of rubber due to its abundant supply and lower production costs.

Natural rubber is widely regarded as the least expensive option due to its abundant natural supply and lower manufacturing costs compared to synthetic rubbers. It is commonly used in applications such as tires, footwear, and seals. However, while it is cheap, it has limitations in terms of performance, particularly in extreme weather conditions or chemical exposure. For applications requiring higher performance, synthetic rubbers like silicone or EPDM might be more expensive but offer better durability and resistance to harsh conditions.

Pros and Cons of Natural Rubber

What's better than silicone?

While silicone excels in high-temperature environments, fluorocarbon rubbers like Viton offer superior resistance to harsh chemicals and fuels. What is Viton rubber?³

Viton rubber offers better resistance to chemicals and fuels than silicone, making it ideal for more demanding industrial applications.

Silicone rubber is well-known for its heat resistance and flexibility, making it perfect for high-temperature environments. However, when it comes to chemical resistance, particularly against fuels, acids, and harsh solvents, fluorocarbon rubbers like Viton surpass silicone. Viton’s resistance to aggressive chemicals makes it the material of choice for applications in the automotive and aerospace industries where exposure to fuels and harsh chemicals is common.

What type of rubber is the best?

The "best" type of rubber depends on the specific requirements of the application. However, for general purposes, synthetic rubbers like silicone and EPDM are often considered top choices due to their exceptional performance in various environmental conditions. What is the best rubber for seals?⁴

Silicone and EPDM are often considered the best rubber options for their durability and resistance to harsh environmental conditions.

The best rubber for your needs depends on the requirements of your application, including temperature resistance, chemical exposure, and flexibility. Silicone rubber is ideal for high-temperature environments and medical applications due to its stability and flexibility. On the other hand, EPDM rubber is preferred for outdoor applications and seals because of its superior resistance to UV light, ozone, and weathering. For general-purpose sealing and gaskets, nitrile rubber (NBR) may be the best option due to its resistance to oils and fuels.

What rubber lasts the longest?

Rubbers like silicone and fluorosilicone tend to last the longest due to their excellent resistance to aging, ozone, and extreme temperatures. What is fluorosilicone?⁵

Silicone and fluorosilicone rubbers last the longest, thanks to their resistance to ozone, extreme temperatures, and aging.

The longevity of rubber depends on its ability to resist aging, ozone, and extreme temperature conditions. Silicone rubber is known for its ability to withstand prolonged exposure to high and low temperatures, making it a long-lasting choice for various industrial and consumer applications. Fluorosilicone, a variant of silicone, offers even better resistance to fuels, oils, and extreme chemicals, making it ideal for applications in the automotive and aerospace industries. In harsh conditions, these rubbers maintain their flexibility and integrity much longer than other materials.
