Resirene SA de CV has launched three new materials in the last year as it diversifies beyond its core polystyrene business.
Earlier this year, the Mexico City-based firm began production of Resalloy-brand additives, sales director Miguel Aguirre said Oct. 4 at the Plastimagen 2011 trade show in Mexico City. Resalloy allows for mixing of polymers “that don't normally mix,” he said, such as PET and ABS regrind.
Late last year, Resirene entered the thermoplastic elastomers market with Resiprene-brand thermoplastic polyurethane. Around the same time, the firm launched Biorene, a bio-based resin that combines 40 percent starch content with PS or polypropylene.
Resirene is making the new materials at its plant in Tlaxcala, where it operates 330 million pounds of capacity for PS. The firm also makes CET-brand styrene-methylmethacrylate there.
“We're staying in polystyrene, but also developing some niche areas so we can grow the company,” Aguirre said.
Resirene's PS sales are expected to be flat this year, as consumer demand remains less than robust. The firm had operated a second PS site near Mexico City, but consolidated all production into Tlaxcala in 2009 in order to be more competitive, Aguirre said. In Tlaxcala, Resirene can make general-purpose and high-impact grades of PS.
Resirene's TPU grades are being aimed at consumer goods, rather than automotive uses, Aguirre added. The firm also can compound those materials to meet customer specifications.
The new bioplastic being made by Resirene can offer better heat resistance than other bioplastics in cutlery and similar applications, Aguirre said. The firm's new additive has been used to combine post-industrial resins into alloys used in printer cartridges, he added.
Resirene employs 180 and is owned by industrial group Grupo Kuo SAB de CV of Mexico City. Grupo Kuo employs 14,000 people and has annual sales of about $1.8 billion.
