MIDLAND, MICH.—Dow Chemical Co. is touting its ethylene styrene interpolymers as ``a major new polymer family'' based on its Insite-brand metallocene technology. Kurt Swogger, research and development director, said the Midland-based firm is running pilot production its Freeport, Texas, facility of small amounts of ESIs. The new material will be produced in semicrystalline, amorphous rubber and ``glasstomer'' structures, which will be commercialized into three different new polymers, he said.
The ``glasstomer'' structure is so-called because of its glassy state at room temperature in spite of being elastomeric.ESIs are expected to have uses in the packaging, wire and cable, toy and automotive markets, he said.
Dow is applying for food-contact approval for the new ESI product, Swogger added.
