Plastic Shim Stock (Color Coded)

All Seals is an industry leader in the production of custom plastic shims.  We are known for precision, color coded plastic shim stock that ranges in thickness from .0005” to .060”.  The shims are color coded in order to assure quick and accurate shim thickness identification.  Our plastic shims are convertd out of a variety of plastic materials; including nylon, vinyl, acetate, polypropylene, polyester and polyethylene and many others and in any required shape.  Plastic shims are long wearing, flexible, impervious to oil, non-hygroscopic (lacking the property of absorbing and retaining an appreciable quantity of moisture from the air), and they make the perfect seal.

Acetal (Delrin®) Gaskets

All Seals converts, stamped, punched, laser cut and water jet cut parts using Acetal, commonly known by the brand name Delrin®.

Polyethylene: LDPE, HDPE, UHMW Gaskets

All Seals converts, stamped, punched, laser cut and water jet cut parts using polyethylene plastic materials; such as Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE) and Ultra High Molecular Weight Polyethylene (UHMW). Polyethylene plastic is characterized by toughness, near-zero moisture absorption, excellent chemical, and electrical insulating resistance properties. Polyethylene plastics are classified by density and the primary differences are in rigidity, heat resistance, chemical resistance, and ability to sustain loads. In general, as density increases, heat resistance, stiffness, and resistance to permeability increase. Low-density polyethylene plastics are quite flexible, with high impact strength and relatively low heat resistance.

Kapton® Polyimide Film Gaskets

All Seals converts, laser cut and water jet cut parts using Kapton® Polyimide Film. Kapton® is a polyimide film developed by DuPont™ which can remain stable in a wide range of temperatures. It can withstand temperatures up to 500°F (260°C). It is used in flexible printed circuits and electronics. Its thermal conductivity properties make it ideal for use in controlling and managing heat in electronic assemblies such as printed circuit boards. Kapton® offers an excellent combination of electrical properties, thermal conductivity and mechanical toughness for its use in electronic and automotive applications.

Kapton® has a unique combination of electrical, thermal, chemical and mechanical properties that withstand extreme temperature, vibration and other demanding environments.

High Impact Polystyrene Gaskets

All Seals converts, stamped, punched, laser cut and water jet cut parts using High Impact Polystyrene. High-impact polystyrene is generally recognized as the best styrene material for load bearing applications. It is a versatile and inexpensive material exhibiting high tensile strength and is light-weight and rigid. High-impact polystyrene has a very good dimensional stability making it suitable for applications in low strength structural projects. It is a suitable material for applications where heavy force or shock is applied over a short period. High-impact polystyrene has a tensile strength of 46-60 Mpa and is suitable for temperatures as low as -20°F. High-impact polystyrene is used by All Seals to produce a range of custom gaskets, seals, washers and components for a variety of applications. Typical applications include food packaging, house wares, and office products. Natural (translucent white) high-impact polystyrene is FDA compliant for use in food processing applications. Pressure sensitive adhesive (PSA) backing can be applied to one or both sides if needed.

Nylon Gaskets

All Seals converts, stamped, punched, laser cut and water jet cut parts using Nylon materials. Nylon is a silky thermoplastic material. It is the first commercially successful and most commonly used synthetic polymer. Crystalline nylons have high tensile strength; flex modulus, impact strength, and abrasive resistance. There are several different types of nylons on the market, the two most regularly used being nylon 6 and 6/6. Nylon 6/6 is the hardest, and it has a significantly higher melting point. Nylons work with little or no lubrication, but lubrication will improve the life and load carrying properties. It is available in a glass filled variant as well as molybdenum filled variant to aid in certain applications. In the glass variant, glass is added to aid in high temperature, structural properties as well as increased impact strength and rigidity applications. The molybdenum variant is used when a moving part requires an extra secretion of fluid for lubricity without the need for manually adding a lubricator to the part. Nylon has a high impact strength as well as abrasion resistance making it a suitable material for parts such as gears and bearings. It has good resistance to most oils and greases and resists a wide spectrum of fuels and chemicals. It will not be affected by insects, fungi, mold or mildew. Nylon has adequate electrical properties for most voltages. All Seals manufactures a variety of nylon washers, nylon gaskets, nylon seals, nylon plates, nylon insulations and nylon strips in all shapes and sizes.

Peek (Victrex Polyetheretherketone)

All Seals converts, stamped, punched, laser cut and water jet cut parts using PEEK. PEEK is a chemically resistant, versatile, high performance crystalline thermoplastic. It was one of the first high performance commodity products available. PEEK has a combination of outstanding properties including: chemical resistance, high mechanical properties, self-extinguishing characteristics, high operating temperatures (ability to perform in water temperatures as high as 500°F), a wide pH range (from 60 percent sulfuric acid to 40 percent sodium hydroxide), and tremendous dimensional stability. It has replaced stainless steel in numerous applications. PEEK is a good choice for many applications including automotive engine parts, aerospace components, compressor valve parts and bearings. 

Polyvinyl chloride (PVC) Gaskets

All Seals converts, stamped, punched, laser cut and water jet cut parts using Polyvinyl chloride (PVC). PVC is an acronym for polyvinyl chloride. It is the mostly widely used thermoplastic next to polyethylene and polypropylene. Its success comes from the plastics versatility; it can be used in a rigid compound or blended with plasticizers to convert flexible plastic grades. PVC offers the most economical solution with first-rate physical properties including: chemical resistance, mechanical strength and self-extinguishing properties. Rigid PVC is widely used in chemical plants because it's superior resistance to chemical substances.

Teflon® (PTFE) Gaskets

All Seals converts, stamped, punched, laser cut and water jet cut parts using Teflon® (PTFE). Polytetrafluoroethylene (PTFE) is DuPont's trademark of Teflon®. It is a synthetic fluoropolymer of tetrafluoroethylene consisting completely of carbon and fluorine. It is innately hydrophobic (repelling water and water containing substances) and has one of the lowest coefficients of friction against any solid. It has excellent dielectric properties as well as thermal insulation with a working temperature range of minus 400°F to 500°F. PTFE is the most chemically resistant plastic known and is unaffected by most corrosive liquids, vapors, and gases. PTFE is generally offered in thicknesses spanning from .002" to .250 thick and conforms to both FDA and AMS specifications, making it acceptable to both medical and food production industries.

PETG Gasket

PETG has high impact strength and good clarity, having an advantage over polycarbonate because the edges have no yellowing or discoloration. It brings increased design freedom and lower fabrication costs. PETG / Spectar® are used in many engineering applications. The gloss can be brought up to a high shine or buffed to a dull finish. PETG has a high chemical resistance making it a good material for food processing and is used where FDA compliance is required.
