Chandler, Arizona, May 30, 2018 – Rogers Corporation (NYSE:ROG) has unveiled a new tacky-surface product construction for its PORON® polyurethane materials that provides a new level of design versatility and flexibility for die-cut foam gaskets and seals.
Until now, PORON materials were typically available in one of three common constructions: foam only (unsupported and often requiring an additional adhesive layer), foam bonded to a PET substrate (supported and also often requiring an additional adhesive layer), or foam bonded to a self-adhesive PET substrate (supported, including an adhesive). The new PORON polyurethane tacky-surface option provides unique benefits in regard to the challenges presented by specific applications.
Typically, die-cut foam parts used for sealing and cushioning in electronics and industrial applications require an additional adhesive layer be added prior to device assembly to hold parts securely in place. Addition of this adhesive layer can be tricky, costly, and time-consuming. Supported with a removable release liner that provides additional functionality, PORON tacky surface material potentially eliminates the step of adding adhesive, saving space in the design as well as time and cost in the assembly process. Or, for designs requiring a higher level of bond-strength, the PORON tacky-surface option used in combination with an added adhesive layer provides an extra margin of security for critical adhesion reliability.
Thin foams used in tight spaces also typically require a supportive substrate, such as polyethylene terephthalate (PET), for structural and handling stability which can reduce the compressibility of the die-cut part due to the inherent stiffness of the substrate layer. Even a self-adhesive substrate sacrifices some degree of compressibility. For ultra-thin constructions, the removable release PET provides handle-ability during the die-cut and assembly process, while maximizing product compressibility once the liner has been removed.
Offered as a non-standard feature, the tacky-surface option further expands Rogers’ extensive portfolio of PORON polyurethane solutions, the first choice of designers requiring high reliability and performance. PORON materials are well known for superior compression set resistance that enables durable, long-term performance for gasketing, sealing, and cushioning.
“We are excited about the possibilities of the new tacky-surface offering,” says Justin Chretien, Product Manager for Rogers Corporation’s PORON Industrial business. “Our foam materials are already easy to fabricate, die-cut cleanly, and work with a broad range of adhesives - this option adds even greater flexibility and versatility for designers.”
