Expandable graphite rubber matrix: SikaRecent Research Landscape

Uncontrolled thermal expansion in sealing or damping components leads to structural failure or leakage under heat stress. Engineering the specific expansion ratio of the rubber matrix ensures precise volumetric filling and mechanical integrity during thermal cycling.

What technical problems is Sika addressing in Expandable graphite rubber matrix?

Insufficient thin layer expansion

(9)evidences

Standard materials fail to provide adequate thermal barriers under high-temperature stress. Enhancing insulation performance prevents structural failure and heat-induced damage.

Surface read-through deformation

(4)evidences

Visible surface distortions occur when internal components or adhesives expand and contract during processing. Eliminating these aesthetic and structural irregularities ensures high-quality surface finishes in bonded assemblies.
