What is Silicone Extrusion?
Silicone extrusions are closed cell silicone lengths that can be extruded into a range of shapes. They have many application benefits across a number of industries and can be used for thermal insulation, vibration damping, sealing flexibility, insulation, noise reduction and thermal shielding.
Silicone Engineering's expanSil™ range of sponge extrusions are manufactured, designed and developed in a continuous production process, allowing for much longer silicone sponge coil lengths. This can help significantly reduce set-up and changeover times and increase your operational efficiency and competitive advantage.
expanSil™ silicone sponge materials can also be produced as silicone sponge seals
