Interfacial Solutions, the leading provider of idea-to-production contract research and development services to the plastics industry, is pleased to announce the launch of four new deTerra biobased polymer grades designed for V0 and V2 flame retardant durable applications. Each grade has been optimized for injection molding, profile extrusion and sheet extrusion applications. All of the grades utilize non-halogenated flame retardants and have biobased content ranging from 70-95%. The products are made from poly lactic acid (PLA), a resource renewable polymer made from natural feedstocks such as corn.

deTerra XP758 meets the needs for high impact, V0 flame retardant durable goods applications made from melt extrusion processes. deTerra XP696 has higher impact strength and provides V2 flame retardant features and has been designed for melt extrusion processes. Both of these products can be profile or sheet extruded and used for indoor applications as a PVC replacement where green or non-halogenated products are a focus, such as in LEED certification.

deTerra XP761 and XP760 are being launched to address flame retardant durable goods molding applications. deTerra XP761 is a high impact V0 flame retardant molding grade while deTerra XP760 is a high impact V2 flame retardant product for molding.

Both the extrusion and molding grades are natural off white in color and function well with commercially available pigments and dyes to allow for a broad range of color options.

All of these products are based on Interfacial Solutions’ patented and proprietary controlled molecular architecture modified PLA technologies and provide the resultant deTerra Biobased Polymers with a unique chemical structure and properties not found in standard PLAs. This process produces a controlled molecular architecture and end groups to minimize polymer chain cleavage and maximized molecular weight. This process gives deTerra improved impact resistance, temperature resistance, melt strength and an ability to control the melt rheology. All of these features allow us to custom formulate deTerra grades to meet our customers’ processing requirements.

An example of the dramatic impact our deTerra products have on melt strength is shown in the picture below. The two photos are from a curtain sheet die and are an example of the improved melt strength of deTerra modified PLA in comparison to unmodified PLA. The higher melt strength give the processing benefits our customers require. The severe necking, a sign of lower melt strength of an unmodified PLA, makes melt processing difficult. deTerra XP759 has increased melt strength that improves both processability and the resultant mechanical properties.

CTO, Chairman and Founder, Dr. Jeffrey Cernohous stated, “deTerra PR146 passes UL E-84 flame testing and was certified as 93% biobased by an independent laboratory. PR-146 was Interfacial Solutions’ first flame retardant deTerra grade. We are now expanding our product offering to include V0 and V2 products for both injection molding and extrusion operations. We are proud to offer the only products having >70% biobased content that meet the demanding V0 and V2 requirements for durable goods applications.”

Interfacial Solutions will be displaying these products and more at NPE 2012 in Orlando, FL on the first floor at booth #62043.
