Poor bonding between expanding polymer foams and rigid substrates like tire components leads to structural failure. Improving interfacial integrity ensures mechanical stability under high-stress conditions.

Standard sealants often fail to fill complex automotive geometries or lack the expansion required for acoustic insulation. Improving expansion and pumpability prevents noise leakage and structural vibration.

Conventional heating methods often result in uneven heat distribution and slow expansion in polysaccharide-based materials. Rapid dielectric heating addresses the limitation of non-uniform cell structure and poor volumetric growth in eco-friendly packaging.

Air and noise leakage through structural hollows. Preventing environmental intrusion and acoustic transmission improves passenger comfort and structural integrity.

Standard blowing agents often suffer from premature gas release or structural collapse during heating. Improving the stability of the expansion process ensures uniform material density and structural integrity.
