January 1991 Additives for Polymers
base raw materials used in their manufacture are also approved in the EEC Specific Commission Directive 9WWEEC.
Epoxidised Soya Bean Oil
Used in food contact plastics, this material is very similar to naturally occurring food constituents. Again this material has international approval. This SCF classification indicates that no further tests are required for food contact.
ATBC
Studies are continuing in the USA on this plasticizer.
High Fat Content Foods
The food packaging films on sale in the UK are in accordance with existing international requirements, in particular the requirements of the EEC Directives (current or proposed). Therefore, the advice given in Appendix II by the FAC that plastics films should not be used for foods of high fat content is contrary to the expert opinion.”

The economics of talc and This is the title of a report compiled by Roskill notation pyrop~llite 1990 Services Ltd., in the UK.
Plastics, especially polypropylene, have provided the major growth market for talc minerals over the last decade, says the report.
It says future growth will be stimulated, in value more than volume, by the demand for talc as a filler for under-the-hood use by the auto market. Applications currently include ducting, shielding, and interior parts. As the plastics content of cars increases, so the talc content is also stated to grow.
The study also points to the greater concentration of companies in the talc supply sector: already two companies, Talcs de Luzenac, France, and Cyprus Industrial Minerals, USA, control 15% of the world market.
The report costs $450 ($900) and is available from:
European market for fillers, extenders and opacifiers
In a report which explores the market for fillers, opacifiers and extenders throughout Europe, leading market research publisher Frost & Sullivan forecasts a rise in sales from the 1988 figure of $3.8 billion to $4.7 billion by 1994.
“Many of these materials are relatively inexpensive silicates obtained by s~~bject~~g minerals to simple refining processes after extracting them from the ground,” the report says. “However, in spite of this apparent simplicity, the applications and markets for them show surprising diversity, dynamism and growth potential.”
