What is the difference between mono and co-extrusion?
There are two ways to manufacture vinyl: Mono- and Co- Extrusion. Both are processes by which liquid polyvinyl is entered into a machine that molds and forms the liquid solution into a solid vinyl unit. Mono-extrusion is a single step process where a consistent blend of virgin vinyl compound and UV protecting agents are sent through the extrusion machine only once. Co-extrusion is simply a two step extrusion process. The first step is for an inner core using less chemicals. Then, the inner core blend is sent through another machine where a thin outer layer of virgin vinyl is extruded or laminated onto the core. The difference between the two is that the mono-extruded vinyl is one solid piece of virgin vinyl and the co-extruded vinyl consists of two similar products extruded together as one.
