Pentcteryfhritol in Pellets This week Celanese brings out an old material in what it says is a n e w and useful form—pelletized pentaerythritol, technical grade. Primary market is the paint industry. Now available in development quantities only, the new PE is scheduled for commercial production before the end of the year. According to Celanese, it shortens the cooking cycle, eliminates dust losses, and makes for easier handling in alkyd resin manufacture. Price is the same as crystalline—32 cents per p o u n d in truckloads.
