Trend towards aqueous and unleaded bonding agents
April I999
Additives for Polvmers
Ciba and Witco exchanged the former’s PVC heat stabilizers for the latter’s epoxies; B&rlocher acquired the metallic stearates business of Mallinckrodt; Clariant bought Albright and Wilson’s phosphorus flame retardant business; Morton Comiel

OxyChem and Great Lakes bought, respectively, the flame retardant businesses of Laurel and Anzon; Most recently, Rohm and Haas has announced a plan to purchase Morton International. In parallel, the major European and North American additives suppliers have been following their increasingly global customers into new regions, in Latin America and Asia. New product development is being driven by competitive pressures, patent expirations, government regulations concerning heavy metals and growth of metallocene-catalyzed polyolefins and engineering resins.

Trend towards aqueous and unleaded bonding agents According to Chemetall GmbH, the Dynamit Nobel speciality chemicals company, the trend towards elimination of solvents, as urged by legislation, is marked in the market for bonding agents for rubber/metal composites. Reduction or complete elimination of organic solvents and removal of heavy metals - are the “buzzwords”, says the company.
Lead additives in conventional bonding systems serve as corrosion-protection for the metal combut ponent, Chemetall identified has “unproblematic” inorganic compounds which can take over this function of the heavy metal. Dr Stefan Dehnicke, Director of Development, comments: “Water-based bonding agents are no longer exotic materials with a restricted field of applications, but industrially mature systems”. Chemetall has been investing in development work and has a number of additional projects in the pipeline.

LEGISLATION For your health’s sake, take PVC (and DEHP) ! In more than 40 years of use in healthcare, not one case has ever been recorded of a patient having suffered from the use of PVC medical products. Since these include flexible tubing, intravenous bags, catheters and protective gloves, rather it can be said that literally millions of people today owe their lives partly at least to this material. This is the core of a strong defence of PVC including the use of grades plasticized with phthalates - mounted by the European Council for Plasticisers and Intermediates (ECPI), in reply to growing attacks from environmental and healthcare groups in the USA.
Already offering a wide range of aqueous bonding systems, Chemetall’s latest product is a completely water-soluble transparent silicone bonding agent (Megum W 25245) for use in high temperature applications such as suspensions for automobile exhaust pipes.
In the USA, the Food and Drug Administration recently stated that alarm was unnecessary. Dr David Feigal, a blood safety specialist from the FDA’s Centre for Biologics, said: “Every product has trace contamination of some chemical. We need to make sure we don’t rush to an alternative that is not as safe as this. Using glass to store blood is riskier because dangerous bacteria seep into glass containers far more easily than into sealed plastic”.
While avoidance of organic solvents has a high priority in the USA and Western Europe, the main issue in Japan tends to be the lead content.
ECPI says that hundreds of studies by independent researchers and government agencies over the past 20 years have not produced any indica-
