Flexible foam sheet is made of starch.KTM KTM Kauppa- ja Teollisuusministeriö (Finnish: Ministry of Trade and Industry) KTM Keretapi Tanah Melayu (Malayan Railway, Malaysia) KTM Kauppatieteiden maisteri Industries, a four-year-old firm in East Lansing, Mich., has developed a proprietary way to extrude extrude /ex·trude/ (ek-strldbomacd´) 1. to force out, or to occupy a position distal to that normally occupied. 2. in dentistry, to occupy a position occlusal to that normally occupied. flexible starch foam. Reactive extrusion of starch foam into sheet using water as the plasticizer plas·ti·ciz·er n. Any of various substances added to plastics or other materials to make or keep them soft or pliable. plasticizer or -ciser Noun and blowing agent is common in making snack foods, but the resulting foam is typically stiff and brittle, adding crispness. But brittleness isn't desirable in packaging. KTM's proprietary formulation adds mineral nucleating agents and biodegradable modifiers to create a flexible foam with a controlled dosed cell structure. The foam is extruded into sheet 2 ft wide and 0.25 to 0.5 in. thick with a corotating twin-screw extruder from Wenger Manufacturing, Sabetha, Kan., a machine normally used in the food industry, not plastics. The flexible foam is used for packaging--e.g., laminated to paperboard. Presented in a paper at the SPE SPE - Software Practice and Experience GEPEC conference in Atlanta in April, the foam was developed in cooperation with Michigan State University Michigan State University, at East Lansing; land-grant and state supported; coeducational; chartered 1855.
