Thermoplastics offer versatility and a wide range of applications. Our product portfolio, which we believe to be one of the most diverse in our industry, includes specialty formulated high-performance polymer materials that are manufactured using thermoplastic resins and elastomers, which are then combined with advanced polymer additives, reinforcement, filler, colorant and/or biomaterial technologies. Garratt worked for DuPont Dow Elastomers, a joint venture of Dupont and Dow (global manufacturers of engineered thermoset rubber and thermoplastic elastomer materials) in market development and product management positions, culminating in a regional commercial leadership role for Europe, the Middle East and Africa.

Complēt™ REC Long Fiber Reinforced Composites Incorporating Recycled Resin The Complēt™ REC portfolio consists of long fiber reinforced composites incorporating post-consumer recycled (PCR) nylon 6 resin, post-industrial recycled (PIR) nylon 66 resin, and PIR thermoplastic polyurethane (TPU) resin.
