Additives for flexible moulded PU foams
Julv 1992
Additives for Polvmers
Introduced in January of this year, Firebrake 415 (a hydrated zinc borate with a temperature of water loss of 415°C) may bridge the gap. Thermal decomposition characteristics fall between those for the Firebrake 290 and 500 grades. Borax believes that PVC materials will prove to be a key application area for the 415 product and has carried out a preliminary evaluation in this polymer system with an alumina trihydrate fire retardant. For further details, contact: Borax Ltd., Borax House, Carlisle Place, London, SWIP IHT, (UK). Fax: -I-44- 71-828-0450.
Petroleum aromatic plasticizers
Tel: +44- 71-834-9070.
Crowley Chemical Co. markets a range of these plasticizers including: VIPLEX 895 - for PVC plastisols and said to replace phthalates by up to 70%. VIPLEX 885 - a non-reactive plasticizer for epoxy compounds, and said to improve water resistance, reduce viscosity, and improve the corrosion resistance. It also improves the tensile strength and impact resistance in polyesters, and reduces the water absorption. VIPLEX 525 and 885 - which replace or extend polyols in foams, asphalt/urethane compounds, shoe soles, and potting compounds.
IS0 certificate for Twaron Pulp
Akzo has been granted an IS0 9002 certificate for the production of Twaron Pulp. This certificate relates not only to the product, which is used in automotive engineering and machine construction, but also for the various supporting services such as purchasing, order and distribution, and plant maintenance.
Additives for flexible moulded PU foams
A new, multilingual brochure now available from Air Products and Chemicals, Inc. highlights the company’s broad line of silicone surfactants for use in moulded polyurethane systems. The publication, which includes English, French, and German text, describes the physical properties and benefits of the company’s silicone surfactants. Also included are four product selection guides designed to help manufacturers determine which of Air Products’ surfactants are most effective in the production of TDI, TDI/MDI and MD1 flexible moulded foams.

COMPANY NEWS New manufacturer of halogen-free fire retardants
Magnifin Magnesiaprodukte GmbH, (Austria) which was established in 1990 in collaboration with Alusuisse-Lonza Holding AG., Zurich, and Veitscher Magnesitwerke AG., Vienna, has commenced production of halogen-free, mineralbased tire retardants under the trade name MagnSim. The company will be capable of manufacturing 10,000 tonnes of this magnesium hydroxide compound per year. Distribution and application technology will be handled exclusively by Martinswerk GmbH, Rergheim, a member of the AlusuisseLonza Group and a manufacturer worldwide of halogen-free aluminium-hydroxide flame retardants under the trade-name Martinal for the plastics industry. Veitscher Magnesitwerke AG has developed a process for the production of MagnSim for halogen-free flame retardance and is itself a leading company in the field of magnesite refractory products. For further information, contact: Thomas Arndt, Martinswerk GmbH, K6lner Strasse 110, 5010 Bergheim, (Germany). Tel: +49-2271-9020. Fax: +49-2271-902557. (See also MATERIALS section of this issue).
CONFERENCES Conference on Flame Retardants
The Flame Retardants ‘92 conference was held in London in April this year. The conference covered a wide range of topics, from EC furniture flammability legislation, to the performance of cable runs in fire conditions. Prominence was given to intumescents, which, under fire conditions, foam to produce an insulating carbon char which both protects the substrate from high temperatures and also allows only a small proportion of polymer to be involved in the fire.
