Dow Performance Silicones, a global provider of silicones and silicon-based technology, showcased new materials and capabilities for electric vehicle (EV) and battery pack designers at last week’s The Battery Show North America 2019.
Specifically, Dow is featured its newest adhesion and conductive materials innovations: DOWSIL EA-4700 CV Adhesive and DOWSIL EC-6601 Electrically Conductive Adhesive. Other industry-leading Dow technologies were also on display.
“Dow’s broad and deep technical capabilities, and our global insights into evolving design requirements and battery industry needs, allow us to offer a robust pipeline of fresh, high-performance material solutions,” said Bruce Hilman, Dow global segment leader for Transportation Electronics. “Through close collaboration with our customers, we are developing advanced new silicone technologies that address broadly relevant manufacturing objectives, such as room-temperature-cure adhesives that reduce both cycle times and the environmental impact of energy-intensive oven curing.”
DOWSIL EA-4700 CV Adhesive for transportation supports faster curing for increased throughput and bonds at room temperature to traditional metals and plastics used in electronics assembly. The material provides the durable adhesion and environmental sealing to substrates used in automotive electronic modules, including aluminum, polybutylene terephthalate (PBT) and polyphenylene sulfate (PPS).
DOWSIL EC-6601 Electrically Conductive Adhesive improves shielding effectiveness and stability in high mechanical stress environments with improved flexibility. Its unique chemistry enables engineers to use it as either a formed-in-place gasket (FIPG) or cure-in-place gasket (CIPG).
Dow’s broad portfolio of thermal management materials are also on display; these products help battery pack engineers and designers to balance difficult thermal materials selection tradeoffs. The company is also featuring a battery module mockup that shows liquid-dispensed silicone encapsulants, gels and foams, which, with low viscosities, are ideal for filling in and around geometrically complex battery module components to reduce the impact of stress and shock and to slow the propagation of a thermal event between individual cells.
