Introduction to seal gasket

With the advent of mechanization era, a variety of machinery and equipment emerge in endlessly, in a variety of mechanical equipment, sealing gaskets become unnecessary parts, is the industrial production enterprises and related industries to solve the gas, liquid medium "run, run, drip, leakage", root cure leakage effective tools.

 As the name suggests, the seal gasket is a seal, mainly play the role of sealing, it is generally used for machinery, equipment, pipelines and other places where there is a fluid through.Used for connection between pipes or parts of equipment.

 Popular at present, the market of sealing gaskets are metal or nonmetal after cutting, stamping or tailor made after processing, such as the common have high pressure asbestos rubber gasket, oil resistant rubber gasket, cylinder gasket, aramid fiber gasket, asbestos gasket, asbestos gasket, rubber mat and so on seven big classes, different material sealing gasket its specific applicable environment is different also, if the gasket failure, not only affects the operation of equipment, sometimes even cause an accident, a threat to the personal and property of people.

 Relevant data shows that different gaskets have their national standards are different, in quality, density, corrosion resistance, lubricity resistance, oxidation resistance and other aspects of strict requirements, as long as all the parameters to achieve national standards, before entering the market.

 Sealing gasket is commonly used in ptfe gasket, with good flexibility, compression resilience, creep resistance, high and low temperature resistance and excellent corrosion resistance, aging resistance, self-lubrication.With its very low leakage rate and excellent heat resistance and radiation resistance, and at the same time very convenient installation and use, is the chemical industry, medicine, petrochemical, food and beverage, electronics, power, metallurgy, shipping and other industries extremely ideal sealing material.

What are PTFE gaskets

All Seals is a recognized leading converter of high quality PTFE gaskets, seals, washers and insulators. 

All Seals has experience in the providing of precision PTFE gaskets, seals, washers, and insulators for a wide range of industries and applications.  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. 

PTFE 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 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. 

PTFE, Unfilled Teflon 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.

PTFE, Filled Teflon Gaskets

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 Teflon 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.

PTFE, Expanded Teflon 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 Teflon possesses no structural weakness or a "grain". Since no additives are required, expanded Teflon also possesses the unique chemical resistance of Virgin Teflon. 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.

Why Choose PTFE gasket making machine?

Efficiently producing: 300pieces/h(large size);More energy saving: the total power only 5KW;More friendly to environment: no PTFE powder splashing but powder output automatically;Intelligent control : producing gaskets by controlling the power quantity;More time saving : the power cut off automatically while the production number set up;Longer working life : no heat while working;high quality components used.

PTFE gaskets are used in many industrial applications, especially the following:

1, Compressor – High temperature and surface-wear resistant sealing gaskets.

2, Electric Motor – Sealing gaskets for components that require corrosion-resistance, exposure to high and low temperatures and high surface wear.

3, Medical Component – Seals for electronic instrumentation using materials that provide secure seals and long product life.  Specialty gaskets, especially miniature sizes, are required for many medical devices.

4, Petrochemical – Gaskets for process equipment that are resistant to corrosive fluids, temperature extremes and surface wear.

Some of the key benefits of non-asbestos gasket sheet

Gaskets are not given the importance which they deserve because of the fact that they are not very much costly. Normally they are overlooked, but capture attention only when problem arises and at that time you need to deal with heavy maintenance costs and this appears as a great issue in the long run. The main function of gasket is to deliver robust seal. Gasket is all about dealing with the imperfections that arise between surfaces that mate. External factors are used for the purpose of compressing gasket into the irregularities that are present between surfaces that meet.

It is believed that even a minor leakage is good enough for causing problems as it enhances the requirements related to maintenance and also the life of boiler is reduced. However, with the gaskets that don’t contain any asbestos you will not have to face such kinds of problems very often.

Removing is also simple and you don’t have to deal with any kind of special requirements such as grinding, scraping or chiseling. This is again another factor which is responsible for bringing a decrease in costs related to maintenance.
Installation is also easy so you are not likely to face any kind of complications. Dangers related to overtightening are not present because the material has amazing strength.

This kind of sheet gasketing is very well suited to the rougher surfaces and you don’t face any kind of special problem. The material used in the making shows enough resilience because of this reason it shows proper compatibility with topography of the surface. With suitable coating the gasket sheet material shows strong resistance towards different kinds of chemical attacks making it ideal for use.
