Elastomer Extrusion

Kemtron produce extruded electrically conductive silicone and fluorosilicone profiles. The process is by pushing the compounded rubber through a die of the desired cross section. After extrusion the strips are then post cured at elevated temperatures for a given amount of time. This post curing maximises the materials physical characteristics and drives off any remaining volatiles and curing agent by-products. The most common profiles are tubes, cords and flat strip. We also have many other standards including D shape, hollow D, Channel sections and hollow rectangular sections. Custom profiles are also available, ask our technical sales team for details. Kemtron’s extrusion process is tight tolerance achieving better tolerances than “E1 high precision” based on ISO3302-1-2014. Kemtron have many extruders ranging from small laboratory capacity for running small and high precision profiles to large high capacity, high pressure machines for long production runs.

Many extrusion dies are made in house by our experienced tool makers which gives us the flexibility to offer fast turnaround times on custom sizes.
