Due to environmental protection and safety requirements, halogen-free flame retardant materials (HFFR) are increasingly used in low-voltage cables and building wires. In order to obtain higher quality HFFR compound, it is necessary to ensure that the high loading of flame retardants can be uniformly dispersed in the polyolefin resin, while processing at the lowest possible melt temperature. A stable and high-precision feeding system also becomes the key to maintaining product purity and consistency.

offer several specific benefits

Co-kneader’s unique combination of screws, pins and barrels can provides low shear which will reduce the breakage to materials’ physical character.

Liquid ingredients can be conducted into melts at designated position which helps customer to achieve the best formula solution.

Temperature prob can immerse into melts through hollow pin in each processing zone so that we can get the accurate real-time temperature all the time .

Opening of two or three inlets & low shearing allow the maximum loading rate of inorganic powders.

The process temperature can be controlled in a narrow zone by precise temperature control of each zone.

Co-kneader’s multiple flights interacted with the pins provides excellent dispersing  effect by increasing the mixing circles.
