Dead sea moves to meet demand for non-bromines
May 2000
Additives for Polymers
Thermosets: non-halogen PCBs are now made to FR-4; higher heat distortion temperatures; Polyurethanes: compatibility with CFC replacements is needed, and non DPO-based FRs. In stabilizers, Great Lakes is investing to add some 30% to its existing production capacity. The plant at Waldkraiburg, Germany, will be doubled and a significant move is an investment of more than $20 million in in-house manufacturing capability of the key HALS intermediate, tri acetone amine. GLCC also has a 50% stake in Gulf Stabilisers, a Saudi Arabian venture that will produce phenolic and phosphite antioxidants and polymer blends for the Middle Eastern market. Great Lakes built up its stabilizers business by the purchase of Lowi in 1993 and the EniChem business the following year. At present the company has only a small position in PVC stabilizers and is looking to further markets in this area. The company estimates the global UV stabilizer market at about 28 000 tonnes, worth $600 million (53% HALS, 41% BZT, by value). Among developments in HALS is a new product (Uvasil 816) a tertiary amine HALS offering better performance (including better resistance to pesticides) in applications such as polyethylene greenhouse film. New BZTs include Lowilite 55, for processing at high temperatures, and Lowilite 94 for PP, with foodcontact approval. A potentially strong weapon for GLCC is its ‘no dust blend’ (NDB) technology, for which it has fought hard in the patent courts. It provides processors with a ‘package’ of up to seven additives in the form of uniform pellets with a certified composition. Offering a tolerance ‘window’ of only ?3% (where powder blends can be up to +20%), it by-passes masterbatching and gives lower investment and operating costs.

Dead Sea moves to meet demand for non-bromines Dead Sea Bromines is planning to enter the phosphorus and melamine-based flame retardants business, from the base of its No 2 position in brominated materials. As a reason, the company identifies European pressure on brominated formulations that has seen a movement in styrenes from brominated diphenyl oxide to other non-DPO retardants such as TBBA and BEO/MBEO. Some electrical and electronics manufacturers are also understood to be replacing halogenated ABS with polycarbonate alloys flame retarded with phosphate-based systems. The company has recently introduced magnesium hydroxide for wire and cable and nylon. All its brominated retardants have been shown to be well below the limits set by the German Ordinance, also passing the incineration test at 900 and 12OO’C to EPA guidelines, with negligible impurities. A tris(tribromopheny1) cyanurate has been introduced to the European market, with 67% bromine content, offering good flow and UV stability with melt-blendable properties for styrene copolymers (FR-245). Also new is tris (tribromoneopentyl) phosphate, with 70% bromine/3% phosphorus, aimed at use with polypropylene. Dead Sea sales are in the region of $500 million, through acquisition and organic growth and chasing Great Lakes.
