Compound, especially made with PP and PE carrier, is also used as filler CaCO3 (calcite: marble powder, limestone). th Calcite is used in almost every sector. Especially bag manufacturers prepare a formula using a 50% calcite-filled compound when filming. Thus, the product is cheaper and its strength increases. Even some bag manufacturers produce bags directly from compound granules filled with 65% calcite produced in Monomex extruders.
In general, these compounds provide a 10-15% efficiency increase in the extruder due to the fact that the heat transfer coefficient of the fillings is higher than polyolefins. Regular flow inside the extruder ensures the dimensional stability of the film/Profile. As it reduces the coefficient of friction, static electrification also decreases. Reduces the cost of raw materials. Increases the thermal welding properties of polyolefins.
LDPE film, HDPE film, Korge pipe, PP sack, injection, PS extrusion are also the main uses of HIPS Antishock, thermoforming and raffia applications. According to the desired properties, it can be formulated together with many side strengthening agents such as impact resistance, UV stabilized, antistatic.
