DAYTON, Ohio—Landstar Inc. has built a demonstration plant in Dayton to test its ``Activated Modified Rubber'' process. AMR is a crumb rubber devulcanization process Victoria, B.C.-based Landstar acquired when it bought Rubber Rebound Corp. earlier this year.
Rubber Rebound, which now is a subsidiary of Landstar, holds worldwide rights to the technology in a joint venture with United Trans-Western Inc., a U.S. firm.
The AMR process was originally developed in China, according to Landstar President D. Elroy Fimrite. It involves chemically treating crumb rubber to break down the sulfur bonds created during vulcanization.
``This is the first plant we've set up,'' Mr. Fimrite said.
According to a company press release, the plant has been engineered to operate with either manual or fully automated controls.
For the next several weeks, the facility will undergo a commissioning period to adjust equipment, formulas and mixing parameters to North American crumb rubber characteristics, the release stated.
After that, Mr. Fimrite said, Landstar plans to establish a compounding laboratory adjacent to the demonstration plant which will develop AMR compounds for specific industries.
``Landstar's mission is to become a significant raw materials supplier to the North American rubber and latex product manufacturing industries,'' the release said.
