Elastomeric materials | weapon company (2023)



Elastomeric materials are measured by material type, composition, and hardness (hardness of the material).

Because there is such a wide variety of elastomeric materials, application is critical to understanding the best mix of materials for the job.











In addition, they are often listed in similar industry specifications (ASTM, MIL, UL, FMVSS, and others).

Foam is a lightweight, open cell product typically used for insulation, filtration, and cushioning. These low-density cellular materials allow air to move through the cellular structure. In addition to traditional foam applications, high density foams have been developed for fluid sealing applications. In contrast, higher density foams will have a higher cell concentration. Medium and low density foams have a lower cell concentration.

The sponge is a material based on expanded rubber. The sponge can be processed in many material preparations (different compositions, densities or open and closed cell structures). The cells are not connected to each other, which means that the material cannot absorb and retain liquids. Sponges are believed to have superior mechanical properties compared to foam.

Sponge and foam are available in sheets, rolls, and molded or extruded forms. They can be ordered with or without "skin" and PSA (self-adhesive glue) as desired.

RUBBER IS OFTEN DESCRIBED AS "SOLID ELASTOMER". In general, the two most popular types of rubber are natural and synthetic. NATURAL RUBBER (GUM) IS OBTAINED FROM THE RUBBER TREE.

Conversely, rubbery materials produced from sources other than the rubber tree are commonly referred to as synthetic rubber.

Although more than 36 synthetic rubber compounds are currently available, not all of them are widely used. Rubber compounds have been researched, developed and developed to meet the needs of many applications, including fluid, temperature and pressure resistance. Many synthetic rubber materials are also available with different degrees of reinforcement, for example insert fabric (CI) or reinforced fabric (membrane). These materials are specifically designed to meet a variety of customer applications.

They are usually installed in a groove to hold them in place when squeezed between two opposing surfaces. In most cases, O-rings are sized by inside diameter (ID) by cross-sectional area (CS). O-rings are especially effective because they have memory and will expand to their original size and shape. Squeezing them between two opposing surfaces thus creates an airtight and/or liquid-tight seal. O-rings are available in various blends of natural and synthetic rubber. Depending on the application, the chosen material can significantly influence the functionality of the O-ring.

Although they are a common product, it can be difficult to select the right O-ring for your application due to thermal resistance and degradation by liquids and gases. In addition, there are different O-ring standards worldwide. The most common standard for North America is AS568. We understand the different mechanical properties of O-ring materials. Contact one of our material specialists today to view your applications or request a quote.

O-rings are available in most polymer compositions and sizes, including AS568B [table below], metric sizes, both molded and endless vulcanized with O-ring cord.

EMI shielding:Electromagnetic interference has become much more important in recent years as the use of electronic devices continues to increase. As the use of these devices continues to increase, so does exposure to a wide range of frequencies. Through years of research and development, manufacturers have determined that electrical insulation, enclosures, and cables have proven to be effective ways to reduce these frequencies.

Organizations such as CE and the FCC have issued guidelines in the form of regulatory requirements for the prevention of electromagnetic interference (noise). For this reason. EMI shielding has become a necessity in the electronics industry. Since there are many different application designs and frequency requirements, different materials have been developed to provide adequate shielding.

Thermal management: In the past, thermal grease was used to create continuity between power sources and heat sinks. Unfortunately, this grease was not ideally suited for applications where ease of installation and cleanliness were paramount. Today, many applications use thermally conductive materials or heat sink systems instead of this lubricant.

Thermally conductive compounds contain fillers that remain flexible during use and provide continuity between mating surfaces. In electronic equipment, air acts as an insulator and must be removed for optimum performance. Electronic device manufacturers want to create an oxygen-free environment to ensure continuity between the power source and heat sink for proper performance. Such thermal management products create continuity in the component to optimize heat dissipation from the power source.

Thermal management products are used in an extensive list of applications. And yes, there is an equally wide range of thermal management options available.

(Video) Elastomer Materials Selection for Hygienic Sealing Applications



Side flow need not be taken into account if a material with sufficient hardness is selected. The compressibility of the cork/rubber can be used instead of more expensive incompressible rubber gaskets. Some of the cork's friction is retained in these products and helps to reduce extrusion and slippage.

Cork/rubber products can contain spongy materials that conform more easily and compensate for minor flange irregularities. This feature is especially useful for stamped or other lightweight assemblies where the available bolt spacing and bolt load are typically low.

Cork rubber products have an extraordinary resilience that helps resist compression deformation and other fatigue effects. Cork rubber gaskets are more resistant to aging than traditional rubber compounds.

Cork rubber joints are used to create and maintain tight contact between the flanges. The most popular synthetic rubber compounds are Neoprene® and Nitrile. However, in special applications cork material mixed with Hypalon®, silicone, fluoroelastomer, SBR or Vamac can be used.

One of the earliest accounts of felting describes how nomads fleeing persecution wrapped their sandals with wool to prevent blisters as they traversed the desert. At the end of the journey, movement and sweat turned the wool into felt socks.

Felt is a textile material produced by matting, compressing and compressing the fibers. Felt can be made from natural fibers such as wool or animal fur, or synthetic fibers such as petroleum-based acrylic or acrylonitrile, or wood-based rayon. Mixed fibers are also common. Felt has special properties that allow it to be used for many different purposes. It is fireproof and self-extinguishing; it dampens vibrations and absorbs sound and can hold large amounts of liquid without feeling wet.

Wool felt is considered the oldest known fabric. Many cultures have legends about the origin of felt. According to Sumerian legend, Urnamman of Lagash discovered the secret of making felt. Stories from St. Clement and St. Christopher says that men wrapped their sandals in wool to avoid blisters when fleeing persecution. At the end of the journey, movement and sweat turned the wool into felt socks.

Today's pressed wool felt is made through a complex process often referred to as "wet processing". The fibers are bonded together by applying pressure, moisture and vibration, then carded and laid crosswise to form multiple layers of fabric. The final thickness and density of the material determine the number of layers that are then steamed, moistened, pressed and cured.

In wet felting, hot water is applied to layers of animal hair. Repeated shaking and squeezing causes the fibers to stick together or weave into one piece of fabric. Wrapping the well-arranged fiber in a sturdy, textured material, such as a bamboo mat or canvas, speeds up the felting process. The felted fabric can be finished by felting.

Specifications: SAE/C-F-206G

Most of the fibers used in pressed felt are wool. Wool fibers have small spikes that aid in the natural blocking or felting process. The production of pressed wool felt is mainly required by SAE standards. These standards define the wool content, density and other physical and mechanical properties of the felt. Pressed wool felt is identified by SAE standards F-1 to F-26.

Lower SAE values ​​will be easier to machine, have better vibration absorption and better wear resistance. Wool felt has excellent moisture-wicking properties. It can absorb its weight in oil several times and when used as a lubricating wick, delivers small amounts of oil at a constant rate. Pressed wool felt has excellent solvent resistance and oil stability. SAE wool felt is resistant to sunlight and retains its original shape after prolonged use.
