CVC Thermoset Specialties (Cuyahoga Falls, Ohio, USA), an Emerald Performance Materials Co., announced in early November that it is expanding its Akron, Ohio facility where Hypro reactive liquid polymers (RLPs) are manufactured. The new reactor system has been commissioned and is scheduled to be on line by late October 2011. The company has undertaken this investment in response to growing double-digit global demand for its Hypro RLPs and HyPox R series products, which are specialty epoxy materials modified using CTBN (carboxyl terminated butadiene acrylonitrile copolymers) RLPs.
The 100 percent liquid polymers based on butadiene and acrylonitrile, have functional end-groups that provide formulators with a range of final product options. Functional groups including carboxyl, amine, methacrylate vinyl, and epoxy enable the RLPs to react into a variety of polymer systems, such as epoxy, UPE, acrylic, polyamide, plastisol and vinyl esters.
“We see great opportunity for our RLP platform,” said John Cech, president of CVC Thermoset Specialties division. “Growing demand for CVC’s technology has been fueled by the increased use of adhesives and composites in more demanding end-use applications as formulators and OEMs seek to replace heavier metals with lighter-weight, corrosion-resistant materials. The new reactor at Akron enables us to keep pace with customer demand and positions us to further expand the range of our product offerings in the future.”
Incorporation of CVC RLPs into thermoset resin formulations reportedly can address challenging performance requirements in applications such as structural adhesives, composites, protective coatings and electronic components by enhancing impact strength, thermal shock properties, peel strength, low-temperature shear strength and crack resistance, as well as long-term durability.
“The base RLP technology was originally developed by one of our predecessor companies, BFGoodrich, about 40 years ago,” added Cech. “However, we have continued to stay abreast of current needs in the marketplace and develop new product and application expertise that provides value for today’s more demanding end-uses.”
In addition to the expansion of its infrastructure, the company recently announced the expansion of this product platform with the launch of novel glycidyl ester based epoxy terminated RLPs. These products are epoxy functional elastomers that are epichlorohydrin-modified CTB and CTBNs. They are solvent and resin free and provide higher Tg, peel strength and lower viscosity in formulations than traditional epoxy adducts.
