Choose A Trusted Glazing Rubber Seal That Won’t Leak

Do you need a rubber extrusion manufacturer to make you glazing rubber seals? Qualiform provides elite rubber extrusion services offering many specs of rubber window glazing seals for many different industries. Maintaining our industry-standard certifications allows our customers to know that we utilize advanced rubber molding technologies with a high-level precision for every project. With our dedication to repeatability and quality, we can produce the ideal rubber window seal extrusions for your application.

What is a Glazing Rubber Seal?

Glazing rubber seals are designed to keep air, water, and other fluids from leaking in or out of the window. They do this by wrapping or ‘glazing’ the piece it molds to creating an extra safe seal. Glazing seals are ideal for residential and commercial properties as a means of minimizing energy consumption and reducing the amount of debris that enters with less effective seals. Glazing rubber seals can be used for weather stripping, window glazing gaskets, window glazing strips, and glazing rubber seal strips. There are also rubber glazing beads, which are much smaller parts while offering similar sealing properties.

With more than 40 years of experience in rubber extrusion, our team at Qualiform develops custom extrusion profiles to suit your specific window configuration. This will increase your glass’s security by providing effective insulation from heat and water and minimizes wear from vibrations.

Taking into account all of our design considerations, our glazing rubber products are intended to deliver a high level of resistance to incredibly harsh environmental conditions. We intentionally stock a full selection of both commercial and specification-grade elastomers so we can ensure your glazing gaskets, seals, and other parts are tailored to your specific application.

Glazing Rubber Seal Applications

The most common application for window rubber seals is weather-stripping insulation for both residential and commercial windows. However, Glazing rubber seals can also be used to secure windows to cars, boats, airplanes, and much more! For instance, marine glazing rubber seals are crucial for increasing the longevity of boats, as it can prevent severe leaks and flooding. Some other applications of glazing channel rubber seals include:

  • Garage Doors
  • Sunroofs
  • Boat Hatches
  • Windshields
  • Drainage Systems
  • Fire Protection

Glazing rubber seals are useful in many different industries due to their insulating properties. Industries such as construction, transportation, marine, electronics, agriculture, and aerospace rely on these seals to reduce contamination in their facilities so their processes can run smoothly.

How to Choose the Best Glazing Rubber Seal for the Job

Determining which glazing rubber seal fits your application properly means choosing the ideal rubber compound for the respective environment. The difference between something like a neoprene glazing channel and an EPDM glazing gasket significantly changes the impact performance. So, choosing the right compound requires careful consideration of various factors:

  • Industry
  • Design specifications
  • Environmental conditions
  • Operating temperature range
  • UV and chemical resistance
  • Installation methods

For example, EPDM is a uniquely versatile compound used in a variety of rubber beading profile applications. Not only does this compound offer reliable performance for window seals, but it is also found in vehicles, safety equipment, medical equipment, and more. However, EPDM has extremely poor resistance to oils, gases, and fuels. Therefore, it should not be used for any applications involving those types of substances.

Here at Qualiform, we offer a comprehensive selection of high-quality rubber compounds to ensure optimal performance in any application.

  • Butyl Rubber
  • EPDM Rubber
  • Natural Rubber
  • Neoprene Rubber
  • Nitrile Rubber
  • Rigid & Flexible
  • Synthetic Rubber
  • Thermoplastic Elastomers (TPE)
  • Viton Rubber

So, how do you know which compound is best for your project? If you are unsure of which compound will provide the performance you need, discuss your options with our technical staff. We are available to answer any questions you have and can provide professional recommendations based on your industry and application.

Materials Used in Rubber Extruded Products

To create a custom rubber extrusion, rubber extrusion companies think about a number of design factors, all related to the application. One of the first things considered is material. Rubber material choice depends entirely on how it will match the application requirements. Then, our rubber extrusion experts plan out the shape of the die. They may also consult their standard rubber die list, but they make new dies for a custom extrusion.

Based on the required properties and application of the finished extrusion, rubber extrusion company, Qualiform can advise on the best material for the extrusion.  Additional consideration will be given to any secondary processes that are required.  Custom compounds and fiber integration can be used when needed.

Natural Rubber
Natural rubber provides excellent acid, chemical and abrasion resistance.

Silicone Rubber
Silicone rubber is an FDA-certified elastomer that maintains its form and properties when exposed to both high and low temperatures.

Viton provides superior heat, chemical and weathering resistance.

Nitrile, aka nitrile rubber, NBR (nitrile butadiene rubber), acrylonitrile butadiene rubber, Perbunan or Buna-Nis, is highly resistant to oils and ideal for O-rings, hoses or hydraulic seals.

Neoprene has high tensile strength and resists heat, fire, UV rays, water and oil.

Butyl delivers low air flow permeability.

SBR (styrene-butadiene rubber) is used in applications that require high abrasion resistance.

EPDM (ethylene propylene diene terpolymer) is ideal for applications that involve heat, aging, ozone, oxidation and ultraviolet rays. Can be used for sponge rubber, foam rubber, weather-stripping, tarp straps, door gaskets, window gaskets and roofing membrane.

Benefits of Choosing Rubber Extrusion

There are many reasons to choose rubber extrusion. First, it offers great freedom of design. You can request parts in nearly shape and size, and rubber extrusion companies can use nearly any rubber material. This means that you also have many choices when it comes to the qualities your part will exude. Another great benefit of rubber extrusion is that it makes parts that are both strong and flexible and soft.
