Invista showcased its Torzen Marathon PA 66 resin, which is said to exhibit excellent property retention when subjected to high temperatures for an extended period. For instance, Invista's Torzen Marathon G3500XHL resin shows 100% tensile strength retention at 210°C after 1000 hours.
"Major market players, such as automotive manufacturers, are asking for lightweight materials that can retain at least 50 percent tensile strength, even after extended use spanning thousands of hours at underhood operating temperatures ranging from 150 to 240°C," said Claudio Degiorgi, Invista Engineering Polymers business leader for Europe and Asia. "Our Torzen Marathon products can meet these needs by delivering a long-lasting heat resistance."
Invista's Torzen Marathon G3500XHL resin is able to retain at least 50 percent tensile strength for more than 4000 hours at 180°C, based on a time-temperature superposition curve. For auto makers, this translates to excellent property retention from 180-240°C during an average lifespan of a car.
In addition to high-performance resins, Invista is developing technical tools for customers and other market players.
"Customers of our Torzen resin receive exceptional service, regardless of the grade they are seeking," said Degiorgi. "We offer molding and design training, technical support during validations and qualifications, and new application development support-including mold flow and FEA analysis."
Many of the tools to begin working with Invista's resins can be found on the company's Torzen brand website. The site's features include:
â–ª An interactive automobile to explore under-the-hood applications
â–ª A materials database to filter and sort resin by properties
â–ª Access to advanced properties and lab tests that reveal stress-strain curves and other behavior
â–ª CAE Modeler tool that enables engineers to export Torzen resin data into any major design program (e.g. ANSYS, Abaqus, Moldex)
Invista manufactures polyamide 66 engineering polymers in the U.S., Canada, the Netherlands, and Argentina, with commercial, technical and distribution facilities in each major region around the globe.
