Seals are among the most versatile products, and navigating the vast array of seals available on your own can be daunting. These seal categories conveniently outline characteristics that may help you determine which seal is right for your needs.
Silicone has high tensile strength, temperature stability in extreme heat, and inertness. In addition, silicone is available in various forms, including solid, sponge, and foam. Each of these forms has distinct advantages as seals.
Because of its closed cell structure, silicone sponge is ideal for environmental sealing. It can be soft (2 – 5 psi) or firm (14 – 20 psi).
Silicone foam, like silicone sponge, has a closed cell structure and is UV stable.
Other advantages of silicone seals include their waterproofness, flexibility, and being shrink-proof.
Neoprene is a synthetic made of polymerised chloroprene, forming a permanent seal. With its resilience, tear strength, and resistance to UV and ozone damage, neoprene can be a useful material if it is not used in conjunction with petroleum-based fuels. In addition, it is highly resistant to temperatures ranging from -40°C to 121°C. Neoprene seals are also water and corrosion-resistant.
Urethane is a flexible, waterproof, and elastic material resistant to ageing and abrasion. However, it is sensitive to high temperatures. Urethanes are available in a wide range of blends and formulations.
EPDM is a waterproof material with ageing and compressibility properties that protect it from UV light, ozone, and oxidation. It is available in a variety of densities. EPDM combines the closed structure of silicone with neoprene’s high temperature resistance (-51°C to 149°C).
