Rubber Extrusion Process
Rubbers are different to thermoplastics, as they are chemically cross-linked during the manufacture. The manufacturing process is very different to that of rigid and flexible materials. The natural rubber is fed into the extruder in strips. As the rubber moves through the barrel it is heated and forced through a die which is located at the end of the barrel. The die contains the cross section of the profile that is required. The profile is the cured through a set of microwaves before being packaged.

Material Types
The following are examples of the most common material types that we extrude. If you have a specific properties or material types that you require we are able to source material specific for your application.
| Name | Properties |
|---|---|
| EPDM | EPDM is in a sense a commodity material but the properties can be modified many ways to enhance specific properties. EPDM has great high and low temperature resistance, good deflection recovery and compression set, excellent weather resistance and UV and ozone resistance |
| Neoprene | Neoprene is similar to the above but demonstrates particularly good fuel and fire resistance. |
| NBR | NBR (Nitrile NBR Rubber) has a high resistance to petroleum oils, aromatic hydrocarbons, and many acids. It also has good elongation properties as well as adequate resilience, tensile and compression set. |
| SBR | SBR (Styrene butadiene rubber) is similar to natural rubber in its resistance to mild solvents and chemicals and, like natural rubber, can be successfully bonded to many materials. |
Key Market Sectors
RIGID PLASTIC
Rigid profiles can be either single material types or co-extruded using a combination of rigid and flexible material types. The rigid profiles we extrude are commonly used in automotive, partitioning, glazing, display and roofing market sectors.
FLEXIBLE PLASTIC
We provide co-extrusion and triplex extrusion providing combinations of material types and colours. The Flexible plastic profiles that we extrude are commonly used for sealing systems or connecting sections between two components.
SOLID RUBBER
We can extrude single or co-extruded rubber profiles combining various material types and colours. We provide cording to reduce shrinkage and silicone application. The profiles we extrude in rubber are commonly used in glazing and curtain walling.
