Basel Introduces Several New PP Brands

<

Basel, a large European polyolefin manufacturer, recently introduced several new PP grades, including new-generation metallocene PP Metocene for injection-drawn and blow-molded bottles and cans, extruded grades for thermoformed sheet and cast film. Adstif, a functionalized PP-oxidized PP produced using a proprietary irradiation technique.
Coleman-Kammula, senior vice president of innovation and asset management at basell, said that the newly developed metallocene PP Metocene can be formed into bottles using standard equipment. The bottle transparency is almost the same as that of PET (wall haze 1.5%, shiny 82%, much better than the general PP), and light weight, the target application is the packaging with low gas barrier property, such as water and juice bottles, excluding carbonate soft drinks and beer packaging. In addition, it can be used for hot filling and packaging without special treatment.
Adstif was prepared using the undisclosed new catalyst in the Spheripol reactor and has the same wide range of processing conditions as the slurry process. Basell previously produced Adstif resin using the Catalloy process. The new Adstif thermoformed cups and containers have higher transparency than PS (GPPS and HIPS blends) prepared with the same products, with high loading and impact strength, and a light weight of about 35%. Oxidation of PP can improve the dispersion of flame retardants in the compound, and therefore can reduce the amount of flame retardant by half, in addition, can also be used in the form of ionomers and nylon blends.
