The main attractions were the giant corporations taking center stage and the dazzling smart devices. Unexpectedly, what really kept me—a professional in the thermal insulation additive industry—pinned to the spot were the unassuming micro-fiber materialbooths—and the chief R&D engineers with furrowed brows at the Potassium Titanate Fiber（whiskers） booth. The one question they repeatedly asked suppliers laid bare the most pressing concern currently facing the thermal insulation coatings industry.

The first half of the thermal insulation coatings competition has concluded—everyone is locked in a fierce battle within the 0.035–0.04 W/(m·K) range, with the differences in the spec sheets now so small as to be negligible. The outcome of the second half lies in the word “additives.” And as an thermal Insulation additive supplier, we, Shanghai Promaterial Industrial are standing right at this inflection point.

Another observation that surprised me was this: the people coming to us weren’t procurement staff—they were all technical experts.

Here’s a small detail: at a forum on thermal insulation technology for new energy vehicle batteries, the presenter showed a slide stating that over the next three years, the compound annual growth rate for thermal insulation fillers capable of withstanding temperatures above 1,000 degrees Celsius while meeting UL94V-0 flame retardant standards would exceed 40%. The entire audience immediately started taking photos.
