Panasonic: New Polypropylene Extends Life Of LEDs

The rapid transition to LED lighting may be facilitated by a new resin development from Panasonic, Osaka, Japan.

The company announced this week that it has developed a light diffusion type polypropylene (PP) resin molding compound, called Full Bright PP. The goal of the invention is to extend the operating life of LEDs.

The material can be used for injection stretch blow molding as well as injection molding.

Pansonic says the material can produce more complex shapes and can be molded with walls as thin as 0.5 mm. The previous best material from the Japanese company generated a hole when a product was blown to a 0.5 mm thickness. Improved chemical resistance is also claimed.

Light resistance stats are interesting: under an environment of 90°C+ UV, there is discoloration after 90 days of exposure (approx. 2000 hours).

According to a report from the U.S., Department of Energy, the market share of LED lighting is expected to reach 84 percent of lumen-hour sales by 2030, reducing lighting energy consumption in that year alone by 40 percent.

Panasonic, a global electronics company formerly known as Matsushita Electric Industrial Co., has developed an interesting portfolio of intellectual property on polypropylene. Last year, Panasonic was awarded a U.S. patent for a high-molecular oriented crystal polypropylene with improved mechanical strength.

PP is of particular interest because of its recyclability.
