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 provides excellent acid, chemical and abrasion resistance.
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.
