Isola 2016 Fact Sheet

Westak Earns UL Recognition for Isola’s 185HR

Westak is pleased to announce UL recognition for Isola’s 185HR laminate. 185HR is a high-performance resin laminate with properties similar to 370HR and IS410. The material was designed to compete with the pricing of imported material, while being produced domestically. Isola’s manufacturing facilities for this material are located in North America and Asia, providing global availability.

185HR is a filled phenolic cured product with 20 to 30% lower Dielectric Loss (Df) properties than other phenolic/epoxy offerings. OEM’s are driving the need for materials with lower Df. Signal integrity testing has shown the loss properties to be similar to FR406.
