Lightweighting, NVH & Battery-Pack Thermal Barriers
Every 100 kg saved adds range. Every decibel removed adds perceived quality.
Density reduction up to 13% in talc-filled TPO, SMC/BMC Class-A panels at lower mass, and hollow-microsphere plates as thermal-runaway propagation barriers between cells.
Application scenarios
01
Injection-molded interior & under-hood parts
PA/PP/TPO compounds with HGS-42 survive high-shear molding while cutting part weight 8–13%.
02
SMC / BMC exterior panels
Class-A surface panels, tailgates, truck components — density from 1.9 down to 1.4 g/cc.
03
EV battery thermal barriers
HGM plates and potting systems slow cell-to-cell thermal runaway propagation with minimal mass increase — validated in eVTOL-grade safety assessments.
04
NVH damping & sealants
Low-density damping pads, seam sealers and underbody coatings.
Why switch — on both ledgers
Economic advantages
- Lightweighting at $/kg-saved far below carbon fiber or aluminum substitution
- Faster cycle times: lower thermal mass cools quicker in mold
- Ships as drop-in — no line retooling for compounders
Functional advantages
- Survives injection molding shear (6,000+ psi grades)
- Isotropic shrinkage → less warpage, tighter tolerances
- Lower NVH transmission
- Thermal insulation inside pack = passive safety layer
