Hiroshima, Japan – Mazda has announced a new resin material that will use to make the world’s lightest bumpers.

Jointly developed with the Japan Polypropylene Corporation, the resin maintains the same rigidity as parts made with conventional materials, but the parts are thinner and require less material. When both front and rear bumpers are made from the resin, the weight reduction is approximately 20 per cent.

The reduced thickness allows for a shorter cooling period when making bumpers. Along with its optimal fluidity, the resin reduces the time required to mould a bumper from 60 seconds to 30 seconds, which substantially reduces the amount of energy consumed during the process.

Mazda plans to use the material to produce the bumpers for the all-new CX-5, which goes on sale this spring, as well as in other upcoming new models.
