Dingjide Petrochemical
External electron donor/cocatalyst
DJD-UD51/55/56
This series of products serves as a special external electron donor for polypropylene Unipol process. The functions of this series of products are as follows: 1. Adjust the isotacticity of polypropylene products and have good isotropic directionality; 2. Inhibit the release of catalyst activity under ultra-high temperature in the reactor; 3. Prevent polymers from forming agglomerates at high temperatures. DJD-UD55 and DJD-UD56 are primarily used to produce homopolymer polypropylene resin, and DJD-UD51 is mainly applied in the production of BOPP film materials.
