Epoxy functional expansible foam matrix: SikaRecent Research Landscape

Thermal bridging and heat transfer through structural gaps increase energy loss and material fatigue. Engineering the expansion ratio and pore structure of these materials creates a high-performance thermal barrier that maintains structural integrity under temperature fluctuations.

What technical problems is Sika addressing in Epoxy functional expansible foam matrix?

Insufficient thin layer expansion

(9)evidences

High heat transfer rates in expanded matrices limit energy efficiency. Reducing thermal conductivity provides superior protection for temperature-sensitive components.

Surface read-through deformation

(4)evidences

Visible surface distortions occur when structural adhesives or foams shrink or expand unevenly during curing. Eliminating these cosmetic and structural defects ensures high-quality finishes on bonded thin-gauge materials.
