Celanese To Raise Emulsion Polymers Prices

Effective June 15 or as contracts allow, Dallas-based Celanese Corp. will raise the prices of
vinyl- and acrylic-based emulsion polymers for all applications as follows: less than 50-percent
solids level, $3.00 per wet hundredweight (cwt); 50- to 54-percent solids level, $4.00 per wet cwt;
and 55-percent and over solids level, $5.00 per wet cwt.

The company attributed the price increases to continued, rapid increases in the cost of raw
materials, feedstocks, energy and transportation.
