What are extruded rubber products or rubber extrusions?
Extruded rubber products are lightweight, flexible, extremely durable and long-lasting. Extruded rubber parts are ideal for use in myriad harsh or extreme conditions, such as high temperature environments or applications with significant chemical exposure. The continuous rubber extrusion process can produce parts in a variety of lengths and shapes relatively cost-effectively and with very little material waste.
Rubber Extrusions: How it Works?
Rubber extrusion is a process used to manufacture rubber products. The process uses an extrusion machine to force synthetic or natural rubber material through a shaped die under high pressure. The material used is typically soft, un-vulcanized rubber. The process shapes the workpiece in a soft, pliable state, after which it is vulcanized to harden the workpiece into a usable final product.
A rubber extruder machine is composed of two primary parts. A heated shearing screw pushes the raw material along a conveyor as compounds are fed into the extruder. As the material moves along the conveyor, it is heated and softened to make it pliable. The softened material is pressurized by the shearing screw and forced into the die where it takes its final shape.
Benefits of Rubber Extrusions
Rubber extrusion is an efficient and economical manufacturing process. The volume of wasted material in the extrusion process is minimal, and the production costs are typically lower when compared to other production methods. Rubber extrusion is a continuous process that can produce finished products of different lengths in a variety of shapes.

Extruded Rubber Profiles
In rubber extrusion, the term profile refers to the shape of the extruded rubber product or the cross-section of the die used. Extruded profiles can be as simple as a “U” shape or highly complex, multifaceted shapes with intricate details. Extruded rubber profiles include:
- D-, e-, J-, L-, P-, and T-shaped profiles
- U channels
- Half-round profiles
- Round cord
- Squares
- Rectangles
Extruded Rubber Seals
Extruded rubber seals are used in a variety of industries and applications to protect from extreme weather, drown out noise, and more. Extruded rubber seals can be manufactured in in a variety of shapes, including:
- Squares
- Cord
- Custom hollow shapes
- Rubber tubing
- Locking gaskets
- Rubber edge trim
