High impact strength, V-0 flame retardant polyester compound debuts

Compounder PolyVisions (Manchester, PA) has introduced a durable, chemical-resistant, non-halogenated flame retardant (FR) graft-modified polyester compound designed for demanding applications. FRX Polymers, Inc. is the supplier of the polymeric FR additive.  The DuraPET product line exhibits excellent processability and outstanding physical properties.

PolyVisions CEO Scott B. Howard:DuraPET FR achieves a combination of impact strength, chemical resistance and flame retardancy not available in any material at any price today.”

DuraPET FR is a graft-modified polyester compound capable of withstanding temperatures from -40°C to more than 180°C. The combination of DuraPET with FRX Nofia polymeric flame retardant has achieved a UL listed (E494117-1755339) V-0 rating at 1.5 and 3.0 mm. The product is said to be suitable for a variety of applications in automotive, transportation, medical equipment, construction, and electronics. It can be processed by injection molding, extrusion (sheet and film), and thermoforming. FRX Polymers’ Nofia polyphosphonate enables DuraPET FR to achieve outstanding FR performance with no compromise to properties and performance. 

“We believe DuraPET FR achieves a combination of impact strength, chemical resistance and flame retardancy not available in any material at any price today,” said Scott B. Howard, CEO of PolyVisions Inc. 

PolyVisions announced that a version of DuraPET FR is also available made from recycled PET. Howard also noted: “Our reactive extrusion process allows us to use post-consumer regrind PET for up to 90% of the formulation. This allows film and sheet producers and injection molding companies to offer an innovative, sustainable alternative for their customers.” 

Marc Lebel, CEO of FRX Polymers, commented: “FRX Polymers is excited that its Nofia polymeric additive has been selected as the FR solution for the DuraPET FR product by PolyVisions.  DuraPET FR exhibits improved properties in addition to flame retardancy not possible using non-polymeric, halogen-free FR solutions. PolyVisions' innovative product demonstrates the value of Nofia polyphosphonates as a performance halogen-free FR additive, what we refer to as “FR Plus."
