Neoprene gaskets resist moisture, chemicals, oils, solvents, heat, and weather. ISP die cuts neoprene rubber for custom gaskets that meet your precise specifications.

Interstate Specialty Products die cuts neoprene gaskets for industrial, electronic, medtech, and scientific applications. We use precision die cutting to convert sheets and rolls of neoprene materials, and can achieve tight tolerances in a wide range of gasket sizes. For low-to-high volume production, Interstate can manufacture the exact neoprene gaskets that you need.

Do you need die cut gaskets for sealing and insulation against water, sunlight, ozone, chemicals, heat, or flame? Are you looking for custom gaskets that can provide cushioning, vibration resistance, or acoustic insulation? Neoprene rubber offers many desirable properties and supports the use of adhesive backings for easy-to-install gaskets. Learn more about custom neoprene seals and gaskets from Interstate.

Neoprene Gasket Advantages

Neoprene is a synthetic rubber made of polymerized chloroprene. Cross-linking during vulcanization imparts specific properties without changing the polychloroprene molecules’ basic structure.

Compared to natural rubber, neoprene offers:

  • Greater resistance to heat and chemicals.
  • Very low oxidation rate, which makes this synthetic elastomer suitable for both indoor and outdoor use.

Neoprene resists:

  • Sunlight
  • Ozone
  • Water
  • Flame
  • Petroleum-based products such as oils, solvents, and greases.

Neoprene Gasket Types

Interstate die cuts custom gaskets made from solid, sponge, and foam neoprene in various durometers and physical dimensions. With our strong material partnerships, we can supply commercial-grade, medium-grade, and high-grade neoprene elastomers. Neoprene supports the addition of other materials, and grade is generally a function of the percentage of neoprene in the compound.

This versatile material also supports bonding with metal and glass. Industrial and electronic applications for neoprene gaskets include power transformers and electrical equipment. Because neoprene is relatively soft, neoprene insulation is also used for padding in medical devices and scientific applications.

Interstate can also die cut neoprene gaskets from customer-supplied materials, or source specialty neoprene for specific applications. For example, FDA neoprene meets CFR 117.2600 requirements for repeated use in food contact applications. UL 94 neoprene resists the spread of flame and is self-extinguishing. Neoprene blends with nitrile and polyvinyl chloride (PVC) resist acids along with oxidation.

Solid Neoprene Gaskets

Neoprene gaskets made of solid rubber are used for sealing machine doors and equipment enclosures against moisture and weather. These gaskets can be die cut from solid neoprene sheets or strips with a pressure-sensitive adhesive (PSA) backing. Most solid neoprene gaskets are made of polychloroprene that ranges from 30 to 90 durometer. Applications include weather stripping and seals for engine compartments.

Sponge Neoprene Gaskets

Custom gaskets made of sponge neoprene can absorb shock and recover quickly. They are die cut from open cell neoprene or closed cell neoprene and may be used as vibration mounts or enclosure gaskets. Open cell neoprene rubber offers excellent compressibility. Closed cell neoprene rubber can meet UL 94 flame ratings, an important requirement for electrical applications.

Foam Neoprene Gaskets

Neoprene gaskets made of foam rubber are flexible, durable, and resistant to air, weather, and moisture. Often, they are used as door seals in transformer cabinets, and for acoustic insulation and cushioning. Like other types of neoprene materials, foam neoprene gaskets support the use of PSAs and other adhesives for ease-of-installation.

Custom Die Cut Neoprene Gaskets

Interstate Specialty Products die cuts neoprene gaskets for indoor and outdoor applications that require resistance to moisture, water, chemicals, oils, solvents, greases, and the spread of flame. We cost-effectively convert solid, sponge, and foam neoprene rubber from sheets and rolls, and can support your operations by supplying custom neoprene gaskets with an adhesive backing.
