Compounding technology firm CRC Polymer Systems has struck a deal with compounder McCann Plastics for commercial production of CRC's Carbelene-brand thermoplastic mineralized elastomer.
North Canton, Ohio-based McCann made commercial amounts of Carbelene for the first time earlier this year. The first commercial product made with the new material was a media storage box for media tray distributor Xpresspax Inc. of Westborough, Mass. The box was molded for Xpresspax by Clinton, Mass.-based Injectronics Corp.
Carbelene is olefin-based and has been in development for several years, according to David Saldo, technical director with Rochester, N.Y.-based CRC. The material originally was designed as a replacement for blends of polycarbonate and polybutylene terephthalate. Carbelene is on average 30 percent less expensive that PC/PBT and can be processed on the same equipment, Saldo explained.
The material also offers better cold-temperature impact, superior chemical resistance and equivalent shrinkage vs. competing materials, CRC officials said.
In addition to the media storage box, CRC is working on Carbelene applications in the automotive market and in industrial applications such as equipment housings, pump housings and machine parts.
McCann has devoted a production line at one of its two North Canton plants to produce Carbelene, McCann business development manager Bill Pappano said. The firm had worked with similar products in the polyolefin market for several years, he added, but McCann officials felt confident about moving into engineering resins because of their good working relationship with CRC.
``We can fine-tune elements like hardness and scratch resistance [in Carbelene],'' Pappano said. ``We're extremely comfortable with the process.''
McCann is one of several compounders that CRC has worked with since CRC opened its doors in 1999. The firm founded by industry veterans Saldo and Todd Ewing develops compound formulations but does not operate its own manufacturing sites. After production, CRC handles all sales and marketing efforts for its products.
CRC opted to work with McCann on the Carbelene project because of McCann's compounding expertise and ability to produce the material in a variety of colors, said Ewing, who serves as CRC's sales and marketing director. Three commercial grades of Carbelene now are available, but Ewing said that additional grades can be specified as needed to meet customer requests.
CRC employs a total of eight at a business office in Rochester and at a technical center in Stanford, Vt. The firm has annual sales of about $15 million. Its customers include numerous plastics processors and most leading resin makers.
McCann operates more than 100 million pounds of capacity for compounds and color concentrates on 15 extrusion lines in North Canton. McCann Plastics operates a 154,000-square-foot compounding plant there, while sister company McCann Color operates a 44,000-square-foot site making color concentrates a mile away.
Both firms are owned by brothers Michael and Jim McCann, who founded McCann Plastics in 1989 and McCann Color in 1998. The firms employ a total of 120 and have combined annual sales of between $60 million and $80 million. McCann Plastics also is the exclusive distributor of rotomolding-grade polyethylene made by Nova Chemicals Corp.
