Silane-modified polyurethane foam chemistry: HenkelRecent Research Landscape

Inconsistent expansion in tire-related sealants leads to structural failure and material waste. Precise control of the silane-modified polymer cross-linking density ensures uniform foam density and mechanical stability.

What technical problems is Henkel addressing in Silane-modified polyurethane foam chemistry?

Inadequate container joint sealing

(10)evidences

Insufficient expansion and adhesion in complex voids like tire interiors or automotive pillars. Effective sealing prevents noise transmission and mechanical instability.

Insufficient structural mortar insulation

(8)evidences

Unfilled hollow sections in automotive structures allow noise, vibration, and moisture ingress. Effective volumetric expansion within bulkheads prevents environmental and acoustic leakage.

Harmful blowing agent emissions

(1)evidences

Standard sealants often fail to reach or fully occupy complex structural voids in vehicle bodies. Effective expansion and pumpability ensure complete acoustic and moisture barriers in hard-to-access areas.
