How Silicone Rubber Is Used for Sealing and Insulation

Silicone RubberHow is silicone rubber used for sealing and insulation? Silicones have valuable properties, but engineers need rubber that meets specific requirements. If you’re wondering whether silicone seals, gaskets, or insulation are the right choice for your application, consider some of the uses for this versatile polymer.    The examples you’ll read about aren’t the only uses for silicone, but they’re representative.

Flame Retardant Rubber for Vehicle Interiors and Electronic Enclosures

Flame Retardant RubberFlame retardant rubber helps to protect people and property from the devastating effects of fire. By stopping or slowing the spread of flame, these elastomers reduce the rate and intensity of burning. They can also limit the release of smoke and toxins while increasing the amount of time that people have to escape from life-threatening situations. Applications for these specialized compounds include electronic enclosures and the interiors of buses, trains, and subways.

For engineers, it’s important to understand that all flame retardant rubber is not the same. There are different classes of flame retardants, chemicals that are added or applied during compounding. There are also different flammability standards by industry and within the same industry. For example, the mass transit industry has so many different flame, smoke, and toxicity (FST) standards that simply asking for an “FST compound” or “flame retardant rubber” risks getting you the wrong material.

Thermally-Conductive Silicone Coated Fabrics for Heat Sink Gaskets

Heat Sink GasketsTechnical buyers and product designers have a choice of materials for heat sink gaskets. Learn about the advantages of thermally-conducive silicone coated fabrics, and how Elasto Proxy creates custom solutions for thermal management challenges.

Computers, telecommunications equipment, and electronic devices generate significant amounts of heat. Unless this heat is dissipated, component damage and system failure can result. By establishing an effective thermal path between a heat-generating component and a metallic heat sink, thermal interface materials dissipate heat and support product life and performance. Some materials, such as thermally-conductive silicone fabrics, also provide properties that strengthen product designs. (more…)

Design Considerations for Acoustic Insulation

Video – Acoustic Insulation Design Considerations

Technical buyers and design engineers need to evaluate all of their application requirements when specifying acoustic insulation. Sound dampening and sound absorption aren’t the same, and some acoustic materials may not be suitable for specific environments or frequencies.

Noisy equipment can cause hearing loss and result in violations that carry fines and other penalties. In North America, regulatory agencies such as OSHA, NIOSH and the Canadian Center for Occupational Health and Safety (OHS) establish workplace limits for noise exposure. Yet the fact remains that noise and hearing loss are the second most prevalent self-reported work-related injury, according to the Hearing Research Laboratory at the University of Ottawa.

Noise can also affect perceptions of product quality. That’s why some potential car buyers listen to how a vehicle’s door sounds when it closes. In a sports car, engine noise suggests speed and power. In a tractor, dump track, or military vehicle, loud engine sounds within the cab are unwanted. For technical buyers and design engineers then, noise mitigation can be about enhancing worker safety, ensuring regulatory compliance, improving the customer experience – or all of the above.

Acoustic insulation is essential, but what are some design considerations? In other words, what do buyers and designers need to know? (more…)

Rubber weather stripping provides either static or dynamic sealing. Sealing pressure is essential, and some elastomers are more resilient than others. Technical buyers and product designers need to compare open cell and closed cell rubber, specify the durometer or hardness, and choose the right compound.

Rubber weather stripping prevents the flow of air and water between two surfaces, such as a door and door frame. Standard weather stripping may be suitable for residential use, but applications in the automotive, building and construction, and electronics industries often require a custom sealing solution. Custom-fabricated weather stripping ensures part quality while speeding installation and reducing material waste.

But what do buyers and designers need to know about weather stripping selection? Let’s take a look. (more…)

Fluorosilicone gaskets combine the high and low temperature resistance of silicones with the fuel and oil resistance of fluorocarbons. Some fluorosilicone gasket materials also resist abrasion and provide EMI shielding. Is fluorosilicone the right rubber for your gasketing application?

Fluorosilicones combine the temperature resistance of silicones with the fuel, oil, and solvent resistance of fluorocarbons. Applications for these extreme-environment elastomers include automotive, aerospace, defense, electronics, and semiconductor manufacturing.

For technical buyers and design engineers, however, choosing the right rubber can involve more than just specifying a temperature range, oil or fuel type, and industry. Is flurosilicone rubber right for your sealing and insulation application? If so, what type of fluorosilicone compound do you need? Some provide specialized properties that you might not expect.  (more…)

Particle-filled silicones are elastomeric compounds that combine the advantages of silicone rubber with the electrical properties of metals. In Part 1 of this series, you’ll learn how shielding silicones support custom EMI gaskets.

Silicone rubber is a synthetic elastomer with useful physical and chemical properties over a wide range of temperatures. Silicones resist weathering, ultraviolet light, oxidation, moisture, and many chemicals. Polydimethylsiloxane (PDMS) compounds are also flexible, permeable, and non-irritating to human skin. With applications ranging from medical gaskets and oven seals to building expansion joints and lubricants, silicone rubbers are versatile materials.
