Soft Gasket

Ordinem Engitech (india) Pvt. Ltd. can manufacture & supply variety of cut shape gaskets. A "Soft Gasket" is a term used when referring to a gasket that is easily compressed under a low bolt load. Soft gaskets are used in a wide range of applications from pipe flange, heat exchanger, compressor and bonnet valve gaskets to name just a few. A soft gasket can be selected from a large variety of Rubbers, PTFE, Graphite, and Compressed Asbestos & Non-Asbestos sheet products.

Types Of Soft Gasket

PTFE

Ordinem Engitech (India) Pvt. Ltd is a Manufacturer & supply of high quality PTFE (Teflon®) gaskets as per various Size and Drawing by CNC cutting machine. PTFE (Polytetrafluoroethylene) is an inert material with excellent chemical resistance, electrical and thermal insulation. These can be used in operations in temperatures ranging between cryogenic (Minus) to 260°C. The material offering non-corrosive, non-wetting, non-contaminating and odourless operation. PTFE gaskets are mainly used in the presence of aggressive chemicals such as acids, bases and solvents.
There are three basic types of Teflon® gasket materials. Virgin Teflon, filled Teflon® and expanded Teflon®

PTFE, Unfilled Teflon® Gaskets (Virgin Teflon® Gaskets)
Virgin grade PTFE (Teflon®) 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 colour compared to mechanical grade PTFE.

PTFE, Filled Teflon® Gaskets
Filled PTFE (Teflon®) 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.

Our most common PTFE filled grades include:
PTFE, Glass Filled Gaskets

• Added in various amounts (5% to 40%)
• Increases compressive strength
• Rigidity and wear
• Reduces creep and cold flow
• Minimal effect on chemical and electrical properties
• Used in applications to decrease cold flow
.
PTFE, Carbon Filled Gaskets
• Added in various amounts (10% to 35%)
• Increases compressive strength
• Hardness, wear and load properties
• Good chemical resistance
• Various types and amounts of carbon can be added to alter conductivity
.
PTFE, Graphite Filled Gaskets
• Added in various amounts (5% to 15%)
• Reduces coefficient of friction
• Reduces initial wear
• Increases strength
• Compatible with most hydraulic fluids
• Outstanding performance in hydraulic/pneumatic compression type rod and piston seals, bearing bands and rotary applications
.

Rubber

Ordinem Engitech (India) Pvt. Ltd., is a Manufacturer of high quality rubber gaskets Rings, and custom Rubber products. Our company’s reputation for excellence has been built on our ability to provide our valued customers with the most effective designing, engineering and converting solutions to meet their most demanding applications. Our main objective is to continuously exceed our customer’s expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service. Rubber is a high-performance elastomer with exceptional resistance to temperature extremes. Silicone moulded and die cut gaskets remain functional within a temperature range of -67°F to +400°F, intermittent to +450°F. The low temperature flexibility of silicone is unmatched by any other elastomer. Rubber gaskets are often chosen due to their excellent resistance to chemicals, water, fire, fungal growth, ozone, heat and aging. Silicone has outstanding tensile strength, elongation, tear strength, and compression set. The versatility and long service life of silicone make it ideal for a wide variety of applications.

Types of Rubber Gaskets
All Seals recognizes the importance of material selection for manufacturing processes; cutting, rubber moulding, rubber extruding, water-jet cutting. We guarantee that we will produce the most appropriate rubber gasket to meet your unique application. All Seals provides customers with range of rubber elastomers to choose from. The most common types of rubber gaskets, we supply are listed below. Our knowledgeable customer service team will gladly assist you in determining which material will perform best in your application.

Neoprene® Gasket (Neoprene® Seal) Chloroprene (CR)
Neoprene® is the trade name for Chloroprene which was the first synthetic rubber. Neoprene rubber is an extremely versatile synthetic rubber used for harsh environment applications due to its moderate resistance to oil and petroleum base solvents. Neoprene exhibits good resistance to ozone, sunlight, aging, and other weather elements.

Silicone Gasket (Silicone Seal) Polysiloxane (VMQ)
Silicone rubber is a high-performance elastomer with exceptional high and low temperature properties. Silicone moulded and die cut gaskets can withstand within a temperature range of -75° F to +500° F. The low temperature flexibility of silicone is unmatched by any other elastomer

Viton™ Gasket (Viton™ Seal) Fluorocarbon (FKM)
Fluorocarbon elastomer Viton™ (a trade name of the DuPont™ Corporation) is a high performance rubber compound known for its outstanding resistance to high temperature and broad range of chemicals. Viton™ rubber’s permeability and compression set are excellent. Viton™ displays good resistance to oils and solvents, aggressive fuels, and concentrated acids.

EPDM Gasket (EEPDM Seal) Ethylene-Propylene-Diene-Monomer (EPDM, EP, EPT)
EPDM rubber is a copolymer of ethylene and propylene. EPDM rubber is one of the most popular, versatile materials available. EPDM is known for its excellent ozone, sunlight, and heat resistance and exceptionally good weather aging properties. Its distinctive ability to stabilize colour and resist harsh weather conditions makes it and ideal choice for outdoor applications.

Nitrile Gasket (Buna-N Gasket) Acrylonitrile Butadiene (NBR)
Nitrile rubber, an extensive ran also known as Buna-N, is the most widely used elastomer for seals and gaskets. Its properties provide superior resistance to petroleum-based fluids, hydraulic fluids, gasoline, alkalis and acids. Nitrile is the polymer of choice for applications requiring oil and solvent resistance.

SBR Gasket (Red Rubber Gasket) Styrene-Butadiene (SBR, Buna-S)
SBR rubber is a synthetic polymer, commonly known as “Red Rubber”. SBR is a copolymer of styrene and butadiene and has properties similar to Natural Rubber. SBR is highly resilient and commonly used because it is cost-efficient and has the ability to deform to uneven flange edges. SBR (red rubber) exhibits excellent impact-strength, high tensile strength, abrasion resistance, heat resistance, and sustains flexibility at lower temperatures.

Butyl Gasket (Butyl Seal) Isobutylene-Isoprene Rubber (IIR)
Butyl rubber is a copolymer of isobutylene and isoprene. Butyl rubber has exceptionally low gas, air, and moisture permeability. It offers excellent weathering properties and has outstanding resistance to sunlight, ozone, heat aging, oxygen, abrasion and tearing. Butyl is used in many applications requiring airtight rubber. Butyl rubber has excellent dielectric properties and is resistant to acids and alkalis.
