Described is a breaking plate for plastic extrusion mainly applied in PVC, which complies with the characteristics of an element for transmitting heat to the inner portion of a plastic mass in the extrusion process; besides promoting the flow homogenization, the invention reduces the inner pressure of the extruder, thus favouring the static mixing of the plastic material along with the additives thereof. The present invention is intended to improve said process and may be applied in the extrusion of vinyl polychloride, the plate being assemblable and includes three pieces, one of said pieces is a beryllium alloy.
