While we offer several standard extrusion profiles, they represent only a fraction of what we are capable of. Our team is able to custom-engineer a wide range of rubber and silicone extruded products for several different industries, including appliance, automotive, and construction.

Rubber Extrusions 101

Elbex - Rubber Basics

Rubber extrusions can assist companies in several different industries, so here are a few quick facts about these versatile products. 

Size Ranges of Extrusions

Rubber extrusions and similar products can be made at various sizes and lengths, depending on their application. At ELBEX, we can produce extrusions at profiles as small as 0.0625 inches. 

We can also manufacture extruded products as wide as 18 inches, up to 8 inches thick (or as small as 0.03 inch thickness), and with diameters as large as 8 inches. 

Market Served: Automotive

Automotive markets

ELBEX has designed and manufactured quality rubber extrusions for a variety of markets. Each market utilizes our products uniquely and requires different profiles. A major market we serve is the automotive sector. 

Automotive Needs 

Profiles for automotive clients are needed to reduce vibrations and create tight seals that offer water resistance. 

For example, our rubber gaskets and seal profiles are designed with those requirements in mind. These profiles can also provide an air barrier, secure components, and offer tight seals. 

Advantages of Using Butyl


There are several types of elastomers which can be used to manufacture rubber extrusions. One of those elastomers is butyl rubber, commonly referred to as butyl. 

Butyl Properties 

Butyl is a common elastomer that has been in commercial use since the 1940s. The ability for butyl to retain air and its flex properties made it ideal for tire inner tubes as its first major application.
