The effect of fire retardants on the flammability ...

Co-extrusion means extrusion of the composite from the materials with different properties as a single array. Co-extrusion involves at least two extruders, which form layered or encapsulated material. With the co-extrusion method, it is possible to design materials with target mechanical, barrier, and aesthetic properties in a cost-saving manner.
