Design Considerations for Acoustic Insulation

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…)

Acoustic Foams for Noise Control in Vehicles and Equipment

Acoustical foams absorb and dampen sounds. Some of these foam rubber materials also provide flame resistance. Product designers need more than just an acoustic foam, however. They need a custom fabricator who can convert stock materials into a custom insulation solution.

Acoustic foams are used for sound absorption and sound dampening in applications such as military vehicles, commercial trucking, and equipment enclosures. They’re usually made of silicone, urethane, or foam-based melamine. Some acoustical foams offer additional properties, such as thermal resistance or fire resistance. For specialized applications, acoustical foams can be added as layers within “insulation sandwiches” that also contain fillers, adhesives, and barrier materials. (more…)

How to Choose Rubber Weather Stripping

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…)

Rubber truck bumpers from Elasto Proxy help keep trucks and trailers on the road instead of in the shop. Learn how these impact-resistant rubber bumpers meet ASTM standards, and are available in 10 different types for vehicle protection.

Rubber truck bumpers help protect trucks and trailers as they backup to loading docks, or when a driver opens the truck’s side doors. They absorb energy from low-speed collisions and low-force impacts while helping to keep trucks on the road instead of in the body shop. These rubber auto parts cost less than truck body repairs, and are easy-to-install with standard metal fasteners such as screws, bolts, and washers.

Rubber truck bumpers are made from elastomeric compounds that can withstand sunlight, rain, snow, and incidental contact with petroleum products and automotive chemicals. SBR and EPDM rubber are good choices because they can handle these road conditions while providing good tensile strength and abrasion resistance. (more…)

Fluorosilicone Gaskets for Sealing and Insulation

Fluorosilicone Gaskets

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…)

Learn how adhesive taping attaches rubber parts to plastic, metal, and glass surfaces – and why taped gaskets provide a strong, reliable alternative to mechanical fasteners such as bolts and screws. Then, download the Make It or Buy It? E-Book

Rubber parts such as door seals, edge trim, and weather stripping can be attached to plastic, metal, or glass surfaces. Mechanical fasteners like screws and bolts are strong and reliable, but installation is time-consuming. The use of adhesive tapes can speed assembly, but taping also offers other important advantages. By understanding these benefits, and how high-strength adhesive tapes compare to mechanical fasteners, you can choose the best attachment method for your rubber parts. If taping is right for your sealing or insulation application, you can then decide which type of taping you need. (more…)
