...ailored to specific processes and applications can be expected in the future. There are still 11 polypropylene producers in Western Europe. Given the increased global competition and the technological leadership of Basell (Spheripol process), ABB (Novolen process), Sumitomo and Borealis (Borstar technology), mergers and acquisitions can be expected to continue the consolidation process not only in Europe but also around the world. It remains to be seen just how the announcements made by the pare...

...f the initiator and increase the MAH grafting rate. At the same time, the styrene reduces the formation of PP macro-free-radicals and subsequent chain scission (β-scission) [2]. The changes in mechanical properties of the composite (matrix: Novolen 1106H) as a function of the chosen MAH grafting formulations (Table2) and the magnitude of the difference from a PP/flax composite conventionally compatibilised with Exxelor PO1020 may be determined from the flexural strength and IZOD impact valu...

...ose by thermal treatment in air or nitrogen, this treatment allowing the carbon fibres to be recovered without damage. The matrix systems consisted of polyamide 6 (grade: Durethan B 29; manufacturer: Bayer AG, Leverkusen) and a polypropylene (grade: Novolen 1100 H; manufacturer: BASF AG, Ludwigshafen). For comparison purposes, conventional carbon fibres and commercially available chopped low-alkali textile glass were used. Two test modifications were employed for the CRP waste. Thermogravimetry ...

... The Conditions The studies were performed with the aid of a co-rotating twin-screw extruder (grade: ZSK-40; manufacturer: Werner & Pfleiderer, Stuttgart/Germany). Various metering devices of the extruder served to introduce polypropylene (grade: Novolen 1100N, manufacturer: Targor GmbH), an adhesion promoter based on maleic anhydride (grade: TP AR 504, manufacturer: Clariant) and, by way of fillers, wollastonite and flax (fibre length: 6 mm) along with chopped PET of 4.4 mm length (fineness: ...

...stances used in food-contact articles). The insolubility of the rutile pigments is evident in their absolute fastness to migration. Migration tests were conducted on eight different plastics (Ultramid B3, Polyclear T 86, Novolen 1100 T, Polystyrene 475 K, Lupolen 6031 M, Polystyrene 144 C, Luran 368 R, Terluran 877), each containing 1% chromium rutile yellow. The coloured plaques were immersed for 10 days at 40°C in different food simulants, usually 3% acetic acid, distilled water, 10% alcohol ...

...e measured in the radial/tangential shrinkage behaviour of semi-crystalline thermoplastics and with reinforced materials. The tangential shrinkage can be influenced 10 % more intensively than the radial shrinkage through the process parameters. For Novolen 1100N, the influence of the process parameters on both the short-term shrinkage behaviour and the moulding shrinkage is presented in Fig. 4 for the samples studied. Of all the parameters investigated, the cooling time and the holding pressure ...

These materials were injection moulded to yield the requisite plastic panels under the parameters usually employed for the materials. The trial presented here focused on COC because this is a ...

New plant types such as the Novolen gas-phase process for PE-HD presented by BASF for the first time in 1964, and improved catalysts such as the possibility discovered in 1968 of immobilizing titanium tetrachloride on magnesium chloride extended the range of products and improved profitability [12]. And ever new applications were c...
