...ailable for polyethylene films (grade: Mikhart MU 08, manufacturer: Provencale). Another product (grade: Filmlink 450, manufacturer: Imerys) has been developed specially for breathable films. One special silica product (grade: Tremin 939, manufacturer: Quarzwerke), manufactured in a sublimation process, is particularly suitable as a reinforcing agent for PU-RRIM. Even plastic itself can be used as a filler. UP granules containing different colouring agents (manufacturer: Dorfner) are incorporate...

...ate powder. It does not, however, provide any information on the crystal habit of the mineral powder, which can vary widely. Figures 1 and 2 show two wollastonite powders prepared by different methods. A nearly block-like wollastonite (grade: Tremin 283 product series, manufacturer: Quarzwerke GmbH, Frechen/Germany) with an aspect ratio of about 2:1 is shown in Fig.1. The wollastonite powder (Tremin 939 product series) in Fig.2, on the other hand, shows an exceptional needle-like structure, char...

Kunststoffe international, 2005-11-21, Fillers: Improved Properties and Processing
Trade Fair Report Improved Properties and Processing Fillers. The trend that was obvious during the past decade continued at this year’s K-Show. The consequences of the increased price of energy, especially oil, together with developments regarding the exchange rate of the U.S. dollar, have had a significant effect on all materials, but especially the filler industry because of the very high freight costs in relation to the value of the product. Increasing transportation costs, in particular, pr...

...udi have together worked out a solution on the basis of Bayflex 180 which suitably matches the complex requirements profile. One special feature of the material grade employed – Bayflex 180 – is the reinforcing material of Tremin 939-304 from Quarzwerke. This contributes towards ensuring that the part surface attains its high toughness over a temperature range of -30 to 150°C and that the very low coefficient of thermal expansion (in the same range as aluminum) is achieved. The Frenzel-Bau Group...

... and long-term availability of the fillers. In this context, high-performance fillers based on wollastonite, mica, and kaolin are particularly suitable for polyamide compounds. Wollastonite: Two of the specially developed wollastonite products are Tremin 283 (Fig. 1), and Tremin 939 (Fig. 2). Tremin 283, made of short needle-shaped wollastonite powders coated with aminosilane, has been used as a functional filling media for polyamides for many years whenever freedom from deformation and high imp...

... ratio lies between 3 and 5, slight reinforcing properties are to be observed, while the warpage, caused by the anisotropic shrinkage, is still very low. Mineral fillers of this category offer a high impact resistance. The wollastonite product Tremin 283-400 (Table 1) is a typical representative of this filler group. If a plastic is reinforced with this product, its modulus of elasticity is far higher than that of an unfilled polymer, but does not reach the level of systems with fillers from t...
