Gasket materials play a vital role in creating effective seals that prevent leaks and ensure the integrity of fluid and gas containment. With their diverse properties, different gasket materials offer unique advantages in terms of resistance to heat, pressure, chemicals, and abrasion. In this post, we will delve into the features and applications of some common gasket materials, shedding light on their functionalities and the scenarios in which they excel.

Black Butyl: Synthetic Rubber Versatility

Black butyl is a synthetic rubber material renowned for its excellent resistance to water, steam, oxygen, ozone, and sunlight. Its low permeability to gases and remarkable vibration damping capabilities make it a reliable choice for various applications, including vacuum seals, tank linings, and window seals.

Black EPDM: Weathering the Elements

Another synthetic rubber material, black EPDM, boasts exceptional resistance to water, steam, ozone, and weathering. Alongside its good electrical insulation properties and flexibility, black EPDM finds utility in outdoor gaskets, hoses, and roofing membranes, where durability and adaptability are crucial.

Black Viton A: High-Temperature Resilience

Black Viton A, a fluorocarbon rubber material, stands out for its outstanding resistance to high temperatures, oils, fuels, solvents, and chemicals. With good mechanical strength and low compression set, it is a preferred option for sealing engines, pumps, valves, and chemical processing equipment.

Black Viton B: Enhanced Chemical Resistance

Similar to Black Viton A, black Viton B offers improved resistance to acids and bases. This material exhibits higher tensile strength, elongation, and durability, making it ideal for sealing corrosive fluids, pharmaceuticals, and food processing equipment.

Blue Nitrile: Versatile Synthetic Rubber

Blue nitrile, a synthetic rubber material, showcases good resistance to oils, fuels, solvents, and water. Its high abrasion resistance and low gas permeability make it a reliable choice for applications such as oil seals, gaskets for fuel systems, and gloves.

Blue Peroxide Cured EPDM: Heat-Aging Resistant

Blue peroxide cured EPDM, a synthetic rubber material similar to black EPDM, offers enhanced resistance to heat aging and compression set. With better color stability, lower odor, and reliable sealing properties, it finds application in seals for hot water systems, steam sterilizers, and food processing equipment.

Purple Peroxide Cured EPDM: Distinctive Identification

Similar to its blue counterpart, purple peroxide cured EPDM boasts resistance to heat aging and compression set. What sets it apart is its distinctive purple color, allowing for easy identification. It is commonly used in seals for pharmaceuticals, biotechnology, and medical devices.

White FDA Nitrile: Compliance with Food Standards

White FDA nitrile, a synthetic rubber material akin to blue nitrile, adheres to FDA standards for food contact. Its white color ensures suitability for sanitary applications. Gaskets for food and beverage equipment, dairy products, and cosmetics commonly utilize this material.
