By extrusion/co-extrusion - Altuglas® resins
The Altuglas® acrylic resins in this range are a specially developed grade for extrusion and co-extrusion.
They come in standard, impact and speciality grades.
Extrusion is a continuous thermo-mechanical process where a polymer is fluidized and forced through a die with the section of the finished part. A long piece of a flat or formed section is shaped (tube, pipe, shape, sheet, leaf, film).
