Manufacturing Custom Rubber Gaskets Since 1951

Manufacturing custom rubber gaskets is the business SRP was built on back in 1951. We have been converting sheet rubber into gaskets, seals, washers, pads, strips, you name it for over 65 years.

The types or sheet rubber we convert into custom rubber gaskets include;

We can supply all rubber gaskets adhesive backed with a pressure sensitive adhesive. Many of these materials meet industry specs for the military, automotive, and aerospace industries.

Below are general descriptions of each of these materials that can be fabricated into custom rubber gaskets:

Neoprene Rubber Gaskets

Neoprene has moderate resistance to oils and gasoline. It features good flame resistance, weathers well, and has very good resistance to abrasion, flex cracking, alkalis, and acids. However, expect poor resistance to aromatic and oxygenated solvents and limited flexibility at low temperatures. Neoprene is generally considered an excellent all-purpose elastomer with a solid balance of properties and few limitations. Perfect for custom rubber gaskets.

Silicone Rubber Gaskets

Silicone features excellent resistance to ozone, sunlight, and oxidation, and is very color stable. It also maintains excellent flexibility at low temperatures, has outstanding resistance to high heat, low compression set, and is a very good electrical insulator. However, it is not recommended for applications which require abrasion resistance, tear and cut growth resistance, and high tensile strength. Silicone is not recommended for resistance to oil, gasoline, solvents, alkalis, and acids.

Nitrile (Buna-N) Rubber Gaskets

Nitrile has very good oil and gasoline resistance, permeability, and heat abrasion resistance. Its resistance to alkalis and acids all increase as the nitrile content of the compound increases. Nitrile must be specially compounded for resistance to ozone, sunlight, and natural aging. It has poor resistance to oxygenated solvents. Nitrile is superior to neoprene in oils and solvent resistance, but is not recommended for applications where it is exposed to severe weathering.

EPDM Rubber Gaskets

EPDM is well known for its excellent ozone, weathering, and aging resistance. It also has excellent water and steam resistance, maintains its flexibility at low temperatures, features excellent resistance to alkalis, acids and oxygenated solvents, and is very color stable. It is not recommended for resistance to oil, gasoline, and hydrocarbon solvents. EPDM is found in a broad range of applications and is excellent for use outdoors.

Butyl Rubber Gaskets

Butyl rubber also has excellent resistance to alkalis and acids and is good for electrical insulation. It has a temperature range of -49°F to + 302°F. Butyl Rubber has a very low resilience, which makes it ideal for vibration damping and shock absorption applications, but offers only a moderate resistance to abrasion and compression. All butyl sheet rubber products can be supplied with Pressure Sensitive Adhesives.

Norseal® Silicone Rubber Gaskets

Norseal® is a line of high performance silicone materials from Saint Gobain. Their unique chemical structure gives them a high temperature stability and general inertness. SRP can custom fabricate Norseal® materials to our customer’s exact specifications for the perfect gaskets, seals, pads, and other products. Norseal® materials are perfect for applications requiring gasketing, cushioning, sealing, insulating, and vibration dampening.

SBR Rubber Gaskets

SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. It has good abrasion resistance, excellent impact strength, very good resilience and a high tensile strength. The temperature range of SBR is -40˚F to 180˚F. SBR can be compounded for use as lining rubber, conveyor belt covers and other extremely demanding applications. SBR is not suited for use with oils, fuels, solvents or hydraulic fluids as opposed to other sheet rubber materials.

Thermoplastic Elastomer (TPE) Rubber Gaskets

TPE is used in a variety of applications in the automotive, construction, medical, food and beverage, electrical, appliance and consumer electronic markets. TPE’s have environmental resistance comparable to general purpose EPDM rubber compounds, while its fluid resistance is comparable to general purpose neoprene rubber compounds; a unique combination that lends itself to a broad range of applications. Its colorability, feel and aesthetics open new design opportunities in consumer applications.

Viton™ Rubber Gaskets

Fluoroelastomers provide premium performance and long-term reliability in very harsh and corrosive environments. Their exceptional resistance to heat, aging and a broad range of fuels, solvents, and chemicals make them ideal for many demanding aerospace, automotive and industrial applications. Fluoroelastomers also offer excellent resistance to weather, ozone, oxygen, and sunlight, and are inherently more flame retardant than hydrocarbon rubber.

Natural Rubber Gaskets

Natural rubber has excellent tensile strength, elongation, tear resistance, resilience, and electrical insulation. Natural rubber exhibits excellent resistance to water and cold flow. Natural rubber has low compression set and can be bonded to a wide range of materials. It also has good flexing qualities at low temperatures that are better than most synthetics, but is not as good as silicone. Natural rubber deteriorates when exposed to oils, fuels, solvents, petroleum derivatives, and hydraulic fluids. Natural rubber has poor resistance to sunlight, oxygen, ozone, and high temperatures.
