1. parallel twin screws barrels has the advantage of lower rotation speed, smaller shearstress between the small screw
2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.
3. parallel twin screws barrels is widely used in PVC products processing, especially for the production of
PVC products with the output over 350Kg / h, because the parallel twin-
screw and
barrel costs less than conical twin-screw and barrel while it has more mature technology.
4. parallel twin screws barrels is successfully applied in PVC plate,
pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.
