  • Rubber Channels for Sealing and Insulation

    Rubber Channels from Elasto Proxy Video: Rubber Channels from Elasto Proxy

    Rubber channels keep window glass from rattling and seal out wind, weather, and water. Learn how to select rubber channels for your application, and how custom channels are fabricated from standard rubber profiles.

    Rubber channels help to secure window frames and hold window glass in place. They eliminate rattling and provide protection against weather, water, dust, rust, and drafts. Most rubber channels are formed through extrusion, a manufacturing process that creates profiles with complex cross-sections and a smooth surface finish. Beaded rubber channels contain stainless steel beads to support installation without stretching or pulling. Unbeaded glass run channels with coated linings are also available.  Continue reading

  • Neoprene Gaskets for Oil Resistance and Outdoor Sealing

    Neoprene gaskets are made of oil-resistant elastomers that also provide weather resistance and environmental sealing. Learn more about neoprene rubber’s applications and advantages, and how finished neoprene gaskets are custom-fabricated from standard neoprene profiles.

    Neoprene gaskets provide resistance to oils, greases, and waxes; oxidation and ozone; and weathering and water immersion. A type of synthetic rubber (SR), neoprenes are a large family of elastomeric materials that are available in various types or grades. Some are compounded with EPDM or NBR to impart specific properties. Chemical, temperature, and flame resistance varies by neoprene compound, but neoprene rubber is generally known for its oil resistance and use in outdoor applications. Continue reading

  • Extruded Rubber Seals: Five Types You Need to Know

    Extruded Rubber Seals - Video Video: Extruded Rubber Seals

    Extruded rubber seals support complex cross-sections and a smooth surface finish. They include bulb, bulb trim, lip, door, and accordion seals. You’ll find all five types in Elasto Proxy’s catalog, along with many other rubber extrusions that are ready for custom fabrication.

    Rubber profiles are made of elastomeric compounds and produced through molding or extrusion. Lengths of standard rubber products are then custom-fabricated to meet application requirements such as length. Rubber molding processes such as injection, compression, and transfer molding have their advantages, but extrusion supports the creation of rubber profiles with complex cross-sections and a smooth surface finish. As a custom fabricator, Elasto Proxy stocks extrusions made of solid rubber and sponge rubber, and can convert these standard products into specialty seals that meet your specific requirements.

    Effective long-term sealing with foam rubber gaskets is a function of compression set and stress relaxation. Learn what these material properties are, why they matter, and how to select the right sponge profiles for custom gaskets under compressive loads. Then, download the Sealing Essentials Guide.

    Foam rubber gaskets provide reliable sealing, cushioning, and insulation in a variety of applications. Products designers and technical buyers can choose sponge profiles made from many different types of foam, and compound selection can be a complex task. In addition to material properties and compliance with industry or regulatory standards, there are many other factors to consider. For example, long-term sealing under constant compression is required for some industrial applications.

    Let’s take a look at two material properties, compression set and stress relaxation, which you may need to consider carefully when choosing foam rubber gaskets for compressive loads. We’ll also look at some common foam rubber materials. Elasto Proxy isn’t a rubber compounder, but we want you to understand how the rubber that’s used in the sponge profiles you ask us to custom-fabricate can affect long-term sealing performance. We keep hundreds of foam rubber profiles in stock, but which one is right for you?
