Types of Rubber used for Gaskets Manufacturing

Types of Rubber used for Gaskets Manufacturing

Besides the above specified types of rubber gaskets, there are many other choices of rubber available for making gaskets. Each rubber has its own durability and advantages to offer.

Nitrite rubber:

This rubber is also known as Buna-N. This is the synthetic type of rubber gaskets, which is the co-polymer of butadiene and acrylanitrite. It can sustain a wide range of temperature, right from -20 degree Celsius to +100 degree Celsius. It has good resistance to water, oil, fuel and come in different thicknesses.

Natural rubber: 

This type rubber gaskets has excellent properties including good tensile strength, abrasion resistance, low compression set, hire tear properties and more. This type is available in various grades and thickness. It is possible to extrude or mold as needed.

Silicone Rubber:

This type has good resistance to high temperature. It can be used from -60 degree Celsius to +230 degree Celsius, based on the grade chosen. This is an inert material that will not react with chemicals. It also has excellent resistance to Ozone and UV rays. It is available in different colors, thickness and hardness.

EPDM Rubber:

This is Ethylene Propylene Diene Monomer rubber, which is of synthetic type of solid rubber. It has outstanding weather resistance properties. It serves best for outdoor uses. Featured with excellent Ozone and UV resistance, has good resistance to vegetable based hydraulic oils and water based chemicals.

Different Kind of Rubber sheets

Different kinds of Rubber sheets

Rubber sheets are existing in huge quantity in market place. Each and every kind of rubber sheets has several characteristics and properties that are completely different from each other. In line with the rubbers used in its composition.  People who don't know how to pick the rubber sheet that is best for his or her homes. While not knowing about the properties of a material that you're unable to declare which one is best and which isn't. 

Usage Of Rubber Sheets 

Totally different sheets perform different functions, some of the rubber materials are used as medical instrumentation, some as electrical insulators and few as fabric material. All of those are sometimes useable at completely different places in line with the requirements. Different types of rubber sheets are given as synthetic rubber sheets, neoprene rubber sheets and latex rubber sheets. so rubber sheets will become very useful in future

Neoprene Rubber Specifications

Neoprene Rubber material is effectively used in many applications. There are several properties for neoprene rubber. Some of the most important specifications of the rubber are,

•             Durometer

•             Thickness

•             Width

•             Tensile strength

•             Temperature Range

•             Elongation percentage

Here is some of the polymer specifications mentioned below.

Commercial Neoprene Style 10

The Durometer Hardness shore of the rubber material is about 40 with about 1/16-1 inches of thickness. The width of the neoprene is 36,48. The corresponding tensile strength of the rubber material is about 800 PSI. The rubber product made out of this rubber can withstand under a temperature range of about -20°F to +170°F. Likewise the specifications differ.

Matte finished Neoprene – Style 12

To illustrate this neoprene style, the durometer hardness shore is about 50 and thickness of the rubber is about 1/16 – 1/4 . Corresponding width and tensile strength is 36 inches and 800 PSI. The rubber can withstand a temperature range of -20°F to +170°F. 

Mid-Grade Neoprene

The Mid-Grade Neoprene Rubber has the resistant capacity towards weathering and moderately resistant to oil and gasoline. To illustrate the specification of this type rubber, if the durometer hardness shore is say 60, then thickness of the rubber is 1/64 to 1/2 with a tensile strength of 1050 PSI and withstand a temperature is about -30°F to +200°F.

 

Neoprene Rubber Foam tape

Neoprene is a recognized synthetic rubber with enormous chemical properties. Based on the thickness of the neoprene rubber, it is extensively used for designing various industrial products. Thick neoprene rubber is used to make rubber sheets, rubber cord, various jewellery items, gloves, shoes, etc.

Foam tapes are available in various densities such as soft, medium and hard. These tapes are used in application such as water, air, dust, gap filling, etc. Tapes are also effective in providing cushion effect, used to avoid vibration and noise in machine, etc. Neoprene made foam tapes have good ageing characteristic and versatile in nature.

Types of Foam Tapes

•        Single sided foam tape
•     Double sided PVC tape
•         Polyethylene single sided tape
•        Polyethylene double sided foam tape
•       Expandable single and double sided foam tape
•    And strongbond double sided acrylic foam tape

Neoprene rubber tapes have pressure sensitive adhesive within it which is effective for industrial and home based applications. It is easy to install, cut, peel and stick it back in the place. These tapes are more effective on doors.

Neoprene Rubber Applications

Neoprene Rubber is used in various industries. Industries like automobiles, medical, electrical, etc. use neoprene products highly for their applications. Rubber products such as washers, rubber sheets, mountings, gloves, etc. Rubber washers are effectively used as sealing agents. Rubber sheets are used in soundproofing applications, baby bedwetting sheets, and floor or ground coverage.

Neoprene Rubber is also used to make river boots. Stiff moulded rubber is used in boots. Further neoprene is used in manufacturing wetsuits, elbow protection materials, spray skirt too. Rubber cords are used to make necklaces and other jewellery. Molded rubber parts that are made up of EPDM or Neoprene material have good resistance to ozone and weather. And these rubber products have good fire resistance and can withhold good temperature range.

To tell about neoprene rubber gloves, they are strong and reusable. Gloves provide great protection again UV materials and solvents. It provides excellent comfortness, high flexibility and sensitivity. It can be used for long period and reusable.

Properties of Neoprene Rubber and its applications

Neoprene Rubber is composed of polymerized chloroprene. This is also known as polychloroprene. Due to the cross linking of polymers like carbon, hydrogen and chlorine; neoprene has great properties like chemical inertness, resistance nature to oil, water and solvents.

Neoprene rubber has more gas permeation resistant property when compared with natural rubber. And the products made out of neoprene have the capacity to tolerate high temperature range of up to 200 degree Fahrenheit. Below zero degrees Fahrenheit, neoprene gets stiff and hard. Neoprene works well with other materials and bonded with metals, steel, aluminium, etc. It has also very low oxidation rate.

 

Applications

•    Power transformers
•    Wetsuits
•    Diving suits
•    Gloves
•    Knee brace
•    Rubber sheets
•    Vibration pads
•     Face mask

Apart from these applications, neoprene rubber belts are effective in reduce fat and helps in body fitness. And different styles of knee braces are made out of neoprene and helpful to safeguard people from minor, moderate and severe injuries. Thus neoprene is used for various applications at different industries.

Neoprene Rubber Properties and Usage

Neoprene rubber is a type of synthetic rubber. The physical properties of neoprene are much similar to natural rubber. It has a good weather resistance and also moderately resistant to oil, heat and ozone fluids. Neoprene is also referred to as polychloroprene. Due to its various kinds of properties, this synthetic rubber can be used in wide range of applications.

Other well known properties of neoprene rubber are, gas permeation resistance, ability to tolerate higher temperature range up to 200 degrees Fahrenheit.  At 0 degree Fahrenheit, this type of synthetic rubber becomes more stiff and hard. Neoprene can be mechanically bond with materials such as stainless steel, aluminium, brass and copper. Moreover neoprene has very low oxidation rate so that it can be used in both indoor and outdoor environment.

 Due to the fire resistant property of latex, it is used in power transformers and many other electrical applications.Wet suits, dry suits, gloves like aquatic protective materials are made out of neoprene because of the thermal resistance property. Since neoprene has high resistance to sun and ozone fluids, it is effective for long term outdoor usage.
