...y, Product Development Product development of polypropylene is still in full flow and stems from improvements in process engineering and the application of metallocene catalysts. Polymerisation processes to be mentioned in this connection are the Borstar technology from Borealis and the multizone circulating reactor technology from Basell [2]. In the past, development of applications of metallocene catalysts was substantially hampered by the patent situation as some of the patent owners blocked...

Kunststoffe international, 2005-11-21, Innovations Today and Tomorrow: Polypropylene for Flexible Packaging
Packaging Polypropylene for Flexible Packaging Innovations Today and Tomorrow. The continuous improvement of flexible plastic packaging – driven primarily by the wishes of the consumer – is being helped along by the constant further development of polypropylene. With both flexible and rigid films – and especially with transparent cast film – enormous progress has been made in the last ten years. An important new impetus has also been provided by the development of new easy-to-open, easy-to-han...

... tailored to needs. For example, isotacticity can be adjusted or specific nucleation technology can be used to modify the products to particular processing techniques and to control the properties to requirements. A special technology (type: Borstar, manufacturer: Borealis) allows production of polypropylene specifically to meet market demands. Moreover, purer products are produced, meeting more stringent customer expectations. Modular Property Design Made Feasible Borstar technology makes i...

.... Further developments in this direction can be anticipated. With regard to polymerisation facilities, the trend towards larger, but also more versatile, units continues. The most recent technological developments in this field are still Borstar PP (Borealis) and Spherizone (Basell). At the same time, innovations on the monomer supply side are important, where rising oil prices are creating interest in processes such as propane dehydration. In the polymer design area, the trend towards producin...

The widely observed rise in the pressures and temperatures employed gives both a better space-time yield and new properties. A good example of this is the Borstar PP process [2] which allows versatile product design due to its modular synthesis of liquid and gas-phase steps. The first plant of this kind, developed by Borealis on the basis of a similar process for low-pressure PE, went on-stream at Schwecha...

Polypropylene - Tailor-made Borealis Producing Bi-modal Polypropylene For a short time now, Borealis has been producing bi-modal polypropylene using the Borstar technology at its Schwechat/Austria location. The company is thus supplying the market with a PP that offers a broad property spectrum and can be processed in a cost-efficient manner. With the opening of a new plant for the production of bi-modal polypropylene (PP) using the Borstar technology, Borealis has reacted to the rapid gro...

Optimisation of random copolymers based on the Borstar PP process can be predicted. Here improvements in incorporation of the comonomer will permit slightly lower initial seal temperatures.

For example, thermoforming can result in cups that are 30 % lighter than usual. The new Borstar process developed by Borealis greatly extends the property and application range of polypropylene [1, 2]. In particular, the production of highly crystalline, very rigid materials opens up the possibility of new application areas for PP, of ma...

Moreover, Boralis displayed PE films made of Borstar FB 2230 and FB 2310, being used in Thailand to cover ponds at fish farms, so that the fish are safe from birds. Fish farmers used to apply sheets of 700 µm thickness before. These new films are half this thick, while at the same time having a better tensi...

A new material aimed specifically at corrugated pipes and injection-molded parts (fittings) is BorECO BA415E, which owes its special molecular structure to the multimodal Borstar process. BorECO BA415E is readily processed, and so makes for substantially higher throughput and lower energy consumption in extrusion processes. The new grade also improves the overall quality and appearance of the pipe, because the ultra-smooth su...

This multi-phase mixture of a semi-crystalline PP matrix and amorphous elastomer phase can be produced either in-situ, e. g. in a multi-stage polymerization process like the manufacturer’s own Borstar PP process, or in a downstream processing step such as a twin-screw kneader. The content and morphology of the dispersed phase largely determine the properties of the material.Basic relationships between the phase morphology of impact-modified PP...
