Spacer Bar & Desiccant System (IGU)
Aluminum or stainless steel spacer bars filled with molecular sieve desiccant, assembled with hot-melt butyl primary sealant and silicone/polysulfide secondary sealant to form the perimeter seal of insulated glass units. Swiggle tape (single-component flexible system) is a growing alternative to traditional box spacer. Sealant failure is the primary cause of premature IGU replacement.

Dow Inc. (Midland, Michigan; NYSE: DOW; ~$45B revenue) is a major global EPDM producer through its Performance Elastomers division, producing NORDEL EPDM. NORDEL is manufactured primarily at Dow's Freeport, Texas complex (one of the largest integrated chemical sites in North America) and at European facilities. NORDEL EPDM is used in automotive weatherstripping, roofing, wire insulation, and plumbing seals. Dow is estimated to hold ~15-18% of global EPDM capacity. The NORDEL brand has been a benchmark EPDM product since the 1960s (originally DuPont, transferred to Dow in 2019 DuPont-Dow merger split). Dow's integrated Freeport site gives it ethylene and propylene feedstock advantages for EPDM production cost.
