Polytetrafluoroethylene (PTFE) is DuPont's trademark of . 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. PTFE Gasket has excellent dielectric properties and provides excellent thermal insulation with an operating temperature range of -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 thickness spanning from .002" to .250" thick and conforms to both FDA and AMS specifications, making it acceptable to both medical and food production industries. Custom Gasket Mfg. can custom manufacture quantities from prototype and short run through large production runs. We will fabricate custom PTFE components to your precise specifications.
Prosaic Steel and Alloys takes pride in its ability to consistently provide precision PTFE () products guaranteed to meet your specifications and function perfectly within your application.
EPTFE (Expanded PTFE) is a Universal sheet EPTFE Gasket material for most services. Seals rough and irregular surfaces. Made from biaxial oriented expanded PTFE sheeting that is laminated to the required thickness. Seals of up to 3000+psi can be achieved depending on the flange type & design and type of media being sealed. Chemically resistant over the Q-14 pH range. Specific gravity: 4 to 6. Suitable for temperatures to 600F.

CONSTRUCTION
Our EPTFE gasket material is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The resulting product exhibits characteristics significantly different than conventional PTFE sheet. EPTFE is much softer and more flexible than regular PTFE sheet gasketing and thus conforms easily to irregular and rough surfaces. In addition, the gasket material is easier to compress and minimizes creep and cold flow.
The three basic types of PTFE () materials include: Virgin , Filled and Expanded .
PTFE, Unfilled Gaskets (Virgin Gaskets)
Virgin grade PTFE gaskets are made from 100% pure material which is used in most general applications. It is extremely soft and formable and is often used for chemical resistant seals and gaskets. It is made directly from the resin producer and has never been processed into a shape. It possesses the highest physical and electrical insulation properties and has increased resistance to creep (compression) under load. Virgin grade PTFE can be recognized by its whiter color compared to mechanical grade PTFE.
Filled PTFE gaskets are made from PTFE which integrates additives and fillers in order to improve the performance of the gasket. This improves the gaskets ability to wear and enhances its unique combination of chemical, physical and electrical properties. Filled is the most common type of PTFE gasket for industrial use as it exhibits improved mechanical strength compared to Virgin PTFE. Glass, carbon and fiber particles are typical fillers that are used to enhance the mechanical strength of the gasket depending on the application.
Our most common PTFE filled grades include:
PTFE, Expanded Gaskets
Expanded PTFE () gasket material is produced by expanding Virgin PTFE using a process that creates a uniform and highly fibrillated microstructure with equal tensile strength in all directions. This means that expanded possesses no structural weakness or a "grain". Since no additives are required, expanded also possesses the unique chemical resistance of Virgin . Expanded PTFE is much softer and more flexible than regular PTFE gaskets and thus conforms easily to irregular and rough surfaces. The material is easier to compress and minimizes creep and cold flow.
Custom Gasket Mfg. fabricates custom PTFE ()gaskets using a broad range of well known PTFE material brands such as; Garlock®, Thermoseal® (Klinger®), Durlon®, Frenzelit®, Flexitallic®and Teadit® in various styles and thicknesses. PTFE gaskets can be supplied with or without pressure sensitive adhesive (PSA) backing.
PTFE Ring Gasket
We are one of the leading manufacturers of a wide range of PTFE Ring Gasket. Our range of PTFE ring and gasket is manufactured using molding method with PTEF method with PTEF granular resin. PTFE, compared with other plastics, has superior properties against chemicals and temperature. The PTFE ring & gasket offered by us is highly admired by all our clients due to their high reliability as well as durability. These ring joint gaskets are especially designed to withstand exceptionally high assembly loads over a small area, thus producing high seating stresses.
PTFE Gasket specification ring gasket, cut gasket, solid ring gasket are available in 1.5 mm, 2 mm & 3 mm, 4 mm, 5 mm thick. Gaskets are manufactured to suite different flange standard like; E/F table, ANSIB-16.5-150, 300 & 600. Class flange, "DIN” standard flanges from 1/2” NB (15NB) to 28” NB. PTFE gaskets are available in raise face size & full face size. PTFE gaskets are also available as per client drawing specification.
We have been counted amongst the most trusted names in this industry engaged in offering a wide array of PTFE Envelope Gasket. Owing to its wide usage and excellent chemical resistance, this gasket is highly demanded in the market. It is used for sealing of pumps and furnaces in electrical and chemical industries. To ensure optimum quality, it is strictly tested on various parameters before dispersing.
Slitted Type : It is available in 0.5 mm to 0.5 mm thick or thickness as per customer requirement.
Milled Type / "U” Type : It is available in manufactured with 0.5 mm flange & gas per customer requirement.
envelope gaskets are also available with Asbestos / Non-asbestos & Steel Filler.
APPLICATION / SERVICE
Our EPTFE is an all purpose gasket material that can replace all other types of PTFE sheet. It will seal all aggressive chemicals over the entire 0-14 pH range except for molten alkali metals and elemental fluorine. Made from 100% virgin PTFE,Our EPTFE gasket material not only resists chemical attack, but it will not contaminate or discolor end products. These industries currently use expanded PTFE gasket material.:
