Many types of thermoplastics can be extruded, including PVC, polyethylene and polystyrene.
Extrusion is a process used to shape plastic by forcing it through a die, creating continuous profiles with a consistent cross-section. This method is suitable for plastics that become soft when heated and solidify again when cooled. At MKM Extrusions the primary material used is PVC, particularly in its unplasticised (uPVC) form, which is commonly used for rigid profiles. Other plastics, such as polyethylene or polystyrene, can also be extruded by other companies who specialise in different materials. At MKM Extrusions we focus on PVC due to its versatility and stability.
