CONTACT SUMMARY 

Notes prepared by Wanita Dunston. 

• TELL US ABOUT YOUR PROCESS AND PRODUCTS. We manufacture high 

pressure industrial laminates and unsaturated polyester sheets in two separate 

manufacturing processes. In the industrial laminates, produce phenolic, silicone, 

melamine, and epoxy laminates. Woven fiberglass and paper are dipped through these 

resins and then through squeeze rolls to a curing oven, and it is semicured. As curing 

occurs, you get VOCs from the oven, and these vapors go to the incinerator. On the other 

end of the oven, the sheets are cut to length (sheet sizes are 31 x 4', 4' x 4', 4' x 6\ and 4' x 

8*) and put into stacks. The stacks undergo hydraulic pressure and platen is squeezed 

together and heated. A solid sheet results. This process is an open mold process. Printed 

circuit board people use the same manufacturing process. In the unsaturated polyester 

process, we employ continuous random mat glass and unsaturated polyester resin in a 

closed mold press. 

• Ray felt as though their prepreg process line doesn't fit into this category; prepregging, 

done here, has nothing to do with unsaturated polyester. 

• ARE THERE ANY SIMILAR PLANTS? Process wise, pertaining to the industrial 

laminates, there are several; Norplex, Ralph Wilson Plastic (Wilson&rt) in Texas, 

Westinghouse in Hampton, NC; Ray mentioned that "they do what Gfegtic does" as far as 

the unsaturated polyester products are concerned only! Glastic does not manufacture 

Industrial laminates. However, the unsaturated polyester products process is not 

controUed by the thermal oxidizer. 

• WHAT TYPE OF OXIDIZER IS USED? The oxidizer is thermal and was manufactured 

by Hirt, which is no longer in business.

• When producing industrial laminates, Iten uses phenolic resins as well as epoxy resins, in 

addition to silicone and melamine resins. In the epoxy resin is acetone. When it is put 

onto the woven glass and placed into the oven, the acetone evaporates off when 

producing the prepreg. 

• When producing polyester sheets, continuous glass mat (fiberglass) is layed on a hot mold 

and resin (unsaturated polyester) is poured onto the glass and then the mold is closed. 

• In the industrial laminate process, a multiple opening mold is used, and the material is put 

into the mold and squeezed. There are negligible emissions while this finishes its curing. 

• PREPREGGING IS LISTED IN THE SURVEY AS AN EMISSION POINT (WHICH 

VENTS TO THE INCINERATOR) HOW MANY LINES ARE THERE, AND HOW 

MANY ARE CONTROLLED? There are 4 total prepreg lines, and Iten controls them all. 

• WHAT ARE THE CAPrTAL/OPERATING COSTS FOR THE OXIDIZER? The 

operating cost is SlO/hr, 3 shifts, with 40 hour weeks...($1200 a week). The 

purchasing/installation cost was $400,000. 

• Ray also stated that General Electric (in Coshoton, OH) does what Iten does; they have 

the same manufacturing process, but make different products. He wanted to know if 

Ralph Wilson Plastics Company is in our source category, he stated that he had visited 

their plant and that they have an incinerator. 

ADDITIONAL QUESTIONS/COMMENTS 

1. Ray Greenwood will be notified whether or not Iten Industries is in the reinforced plastics 

composite source category. In addition, we will find out whether or not Ralph Wilson Plastics 

Company is also in the category. 

2. Ray provided the following information about the oxidizer operation: the volumetric flow ^j) 

rate is 15,000 cfm; the destruction efficiency is 95% by design, and 96% obtained by actual C1«A MP^ 

testing. (The capture efficiency has not been studied). . \M [^ r 

3. WHAT IS THE INLET CONCENTRATION OF HAP CONSTITUENTS, (OTHER 

THAN STYRENE), INTO THE OXIDIZER? (Ray stated that Iten emiu no styrene, no MEK; 

however, styrene is listed as a HAP constituent in the feedstocks for the Closed Molding process, 

as per Table 1., of the survey. It also cites unsaturated polyester resin, with styrene content, as a 

feedstock). 

•Ray clarified each of Iten's two manufacturing processes:
