The following briefs were gathered by Plastics News reporter Frank Esposito from the Society of Plastics Engineers regional technical conference held Sept. 30-Oct. 1 in Akron, Ohio.
APA makes its first public appearance
Advanced Polymer Alloys, the company launched when four DuPont Co. employees bought that firm's Alcryn synthetic rubber line, made its public debut at the Society of Plastics Engineers regional technical conference in Akron.
APA went on its own in June and foresees 10 percent annual growth for Alcryn, which APA vice president E. David Santoleri described as ``one of the most rubber-like TPEs you'll find anywhere.''
Alcryn, with annual sales of $20 million, has found automotive applications in window lace and weatherstripping as well as several injection molding applications.
APA had previously announced plans to add employees within six months of its founding.
Santoleri said he and his three partners — W. Robert Abell III, Jeff Armour and Niles M. Poore, who all had worked with the Alcryn line — saw an opportunity in going on their own.
``If a product is under $100 million, DuPont's not interested in it,'' Santoleri said. ``Our big focus has been on establishing a successful start-up. It's not just like we all got new phone numbers.''
APA is based in Wilmington, Del., with its manufacturing site in Chicago. Alcryn is distributed throughout North and South America, Europe and the Asia Pacific region.
Plasticolors touts Santoprene colorants
Plasticolors Inc. focused on flexible solutions for thermoplastic elastomers, including a line of colorants specifically designed for Santoprene 8000-brand TPEs, at the SPE regional technical conference.
The Ashtabula, Ohio-based colorant and compound manufacturer offers a broad range of color options and hard plastic concentrates to enhance the basic properties of softer TPEs, according to technical and quality control supervisor Earl Throckmorton.
The Santoprene 8000 colorants were previously difficult or impossible to achieve in a thermoplastic vulcanizate, according to the company.
Plasticolors also produces customized flexible concentrates that can be used in ``soft-touch'' products when the integrity of a base resin needs to be maintained.
``We're optimizing value all the way through to the precolor,'' Throckmorton said.
Teknor Apex reveals new line of TPEs
Teknor Apex is touting oil resistance as the best trait of its new line of Flexalloy OR-brand thermoplastic elastomers.
The Pawtucket, R.I., firm unveiled the new PVC/elastomer blends at the SPE regional technical conference.
The blends, which are being produced in five injection molding grades, are based on new resin and stabilization technology as well as advanced polymeric modifiers, according to company officials.
Flexalloy OR can be used in appliance, automotive, footwear and wire and cable applications or other products that are exposed to hydrocarbon-based oils, animal fat or automotive fluids, the company said.
Teknor Apex officials said the new blends match more expensive oil-resistant TPEs such as polypropylene/nitrile rubber blends and chlorinated polyolefin blends.
