Automotive headliner created from a plant base
Johnson Controls unveiled an “environmentally friendly”
automotive product, Ecobond, a headliner that is in the final stages
The Ecobond headliner is lightweight - comprised of
50 percent biomaterials by mass - that fully meets customer requirements
for strength, performance and acoustics.
The production process for the Ecobond headliner relies
on soy-based adhesives, a soy-based urethane core foam, and natural fibers,
reducing the need for non-renewable resources. The headliner is made
via the use of an existing technology that Johnson Controls established
for its Polybond™ process. Soy-based polyols are blended with petroleum
polyols to create a foam core.
Natural materials, including hemp, flax and knaf, replace
the fiberglass that is traditionally used in headliner production. Finally,
a soy-based urethane is used to bond materials and create a semi-rigid
product. The Ecobond headliner satisfies customers’ design requirements
for stiffness, toughness and acoustics. It also is lighter than standard
thermoplastic headliners. Using the new Ecobond approach is not expected
to add costs to the headliner production process.
Other earth-friendly products from Johnson Controls
include EcoCore natural-fiber door panels, as well as soy-based seating
pads, which will be featured on numerous 2008 model-year vehicles.
