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.

FDA Gasket Materials for Food Contact Applications

FDA Gasket MaterialsFDA gasket materials are used in food contact applications such as commercial kitchens. They meet strict standards from the U.S. Food and Drug Administration (FDA), a regulatory agency that’s responsible for protecting the public health by ensuring the safety and quality of many food products. The FDA’s jurisdiction is limited to the United States, but FDA standards are followed worldwide.

FDA gasket materials for food contact applications are subjected to rigorous testing. They are non-toxic, non-marking, non-allergenic, and reliable over a wide range of temperatures. These compounds are also tasteless, odorless, and resistant to the natural growth of bacteria. Not all food-grade rubber is FDA approved, however, so it’s important to choose gasket materials with care. (more…)

NSF Gasket Materials for Food Equipment and Drinking Water Systems

NSF Gasket MaterialsNSF gasket materials are used in commercial food service equipment, water treatment or distribution systems, and other applications that can affect human health and safety. Rubber compounds that are registered with NSF International (formerly the National Sanitary Foundation) must pass rigorous tests to ensure that potentially harmful substances won’t migrate from the gasket material when in contact with food or drinking water.

NSF standards aren’t regulatory requirements, but failing to use NSF gasket materials can put larger product designs at risk. Conversely, using NSF certified compounds can increase the likelihood of regulatory acceptance. In some jurisdictions, public authorities such as health departments require food service equipment and drinking water systems to meet a specific NSF standard. Buyers also expect to see an NSF mark on products such as commercial ovens or water filtration systems. (more…)

Silicone Seals for Food Service Equipment

Silicone Seals for Food Service Equipment

Learn how Elasto Proxy helped a manufacturer of food service equipment solve a sealing and insulation challenge with food prep tables.

Food prep tables and other food service equipment generally features stainless steel construction. Strong, durable, and corrosion-resistant, stainless steel is easy-to-clean and ideal as a food contact surface. Surface finishing treatments such electropolishing inhibit bacterial attachment and biofilm formation, which helps to prevent foodborne illness. Food prep tables with refrigeration systems also help keep ingredients at the proper temperatures for freshness and taste.

By following proper procedures, stainless steel surfaces can be kept shiny and clean. That includes metal surfaces where items like sandwiches and salads are assembled, as well as the pans and shelves that hold the ingredients. Yet food prep tables are built with non-metallic materials, too. Silicone seals fill slots and surround metal edges in food storage areas. They cover sharp surfaces, seal gaps, and support refrigeration. All silicone rubber is not the same, however, so it’s important to choose the right compound. (more…)

High Temperature Seals for Commercial Ovens

High Temperature SealsIn this case study, you’ll learn how Elasto Proxy helped a commercial oven manufacturer solve a sealing and insulation challenge. By applying our technical design, compound selection, and custom fabrication expertise, we provide high temperature seals for bakery and pizza ovens. How can we help you?

Commercial ovens don’t just need to achieve and maintain the proper cooking temperature. In busy environments such as sandwich shops, bakeries, pizzerias, and convenience stores, a commercial oven’s cooking speed and ease-of-use are also important. Oven door seals aren’t as bright and shiny as a brand-new stainless steel oven, but these rubber parts can shine brightly in their own way.

When a popular restaurant chain began toasting its sandwiches, a commercial oven manufacturer faced a challenge with high temperature seals for oven doors. The manufacturer’s oven contained a moveable tray that held sandwiches during cooking, but that caught on the door seal whenever a sandwich was removed. Eventually, the overlap between the rubber seal and the metal tray caused the oven seal to loosen. (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…)

NSF/ANSI 61 Gaskets for Drinking Water Systems

Video – NSF/ANSI 61 Gaskets for Drinking Water Systems

NSF/ANSI Standard 61 establishes health-related requirements for rubber seals and gaskets used in potable water systems. Learn how NSF/ANSI 61 can affect your project’s costs, how there’s a difference between NSF/ANSI 61 complaint and NSF/ANSI 61 approved materials, and how water jet cutting and infrared splicing create high-quality custom rubber gaskets.

Custom rubber gaskets that are used in drinking water systems need to be free from chemicals that can leach into water supplies and affect human health or cause unpleasant tastes and odors. Additives such as plasticizers, antioxidants, and solvents are designed to impart desirable material properties, but can react unfavorably with water treatment chemicals such as chlorine. Leachates from rubber gasket materials can also affect the formation of fungi, algae, and bacteria.

Technical buyers and product designers whose organizations specialize in drinking water systems are familiar with these problems already. Building and construction companies also need to understand the risks – and the requirements for mitigating them. By choosing a gasket fabricator that understands requirements such as NSF/ANSI 61, you can source the right materials and receive high-quality plumbing components that support your projects. (more…)
