The peroixde crosslinded cable compounds (also know as PEX-A) are mainly used in the wire and cable industry as an insulating material for medium and high voltage power cables. The compounds must strictly meet the quality requirements,such as cleanliness,dielectric strength and lifetime. In the first step, polymer and additives are mixed at a narrow temperature range to reach a homogeneous status and then filtered and pelletized. In the second step, liquid peroxide is precised metered and mixed with the pellets.The entire process must be precisely controlled to obtain high purity products.

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 peroxide is strictly metered and mixed with pellets separately to assure the best quality of compounds.

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 .

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

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

Co-kneader’s screw profile can be changed by adjusting the serial of modular designed screw. It makes the compounding system adaptable to all requirements.
