Additives for Polymers
figures for Western Europe which can be compared. Townsend estimates this region at 26% of world sales, or about $4.1 billion. But, if the figures for fillers, plasticizers and pigments are deleted from BCC’s market estimate of $6.63 billion, it leaves only an estimated $2.48 billion sales for those additives covered by the Townsend study. Which is the more reliable? On this data, it is impossible to say. The only reliable conclusion is that it would be helpful to those making and using additives (and considering their future investment) if the research agencies could agree on their terms.

EQUIPMENT Intensive mixing by shear forces A new mixer, particularly suited to freeflowing powders, has been introduced by Hosokawa Mikron BV. Operating by the use of shear forces, the Cyclomix is conical and is filled to about 50% of its capacity.

‘Single hit’ colour matching will raise productivity Offering a new level of user input and sophisticated programming techniques to increase productivity and profits, the latest version of the ProPalette colour formulation system by GretagMacbeth is designed specifically for the plastics, paint and coatings industries. For ‘single-hit’ colour matching at all levels of opacity, the latest version (which gives a seamless transition for existing users of the system) has database improvements which offer users considerable flexibility with data, as well as improvements to the user interface giving better efficiency. Innovative colour utilities are also provided, which streamline the analysis of the data and improve the productivity of the system.

New software extends DSC systems Considerable time has been saved and throughput increased by Courtaulds Coatings, by up-grading the differential scanning calorimetry (DSC) system in its laboratories.
A central high-speed rotating shaft is driven from the mixer cover (so removing seals and bearings from the area of the product). Paddle-shaped mixing elements rotate close to the inner wall and their high speed plus the conical shape of the mixing vessel transport the product from the bottom of the chamber to the top, intermixing the particles by friction against the wall. On reaching the top, the product flows down again into the centre. Special features of the Cyclomix are: fast intensive mixing, widespread applications, self-emptying, no seals and bearings in the product zone and good control over the product temperature.
Data capture has been considerably improved and it is now possible to control the existing DSC 30 model in the laboratory directly from a personal computer, manipulating and evaluating data exactly as required.

With the new Version 5 of Mettler Toledo’s Star software, it is possible to collect a wealth of extra data direct from the measuring cell, including model-free reaction kinetics and alternating DSC measurements.
