Foster Compounds
The building blocks of advanced medical devices are polymers tailored to achieve specific performance properties. For over two decades, Foster Corporation has been a leading supplier of these custom compounds for minimally invasive devices, blending standard polymers with performance additives or other polymers to achieve properties specific to each device. Now part of PolyMedex Discovery Group, Foster continues to provide medical device manufacturers with precision polymer compounds.
At the center of the manufacturing operations in our Putnam, CT and Las Vegas, NV facilities are co-rotating twin screw extruders ranging in size from 27-53 mm. A Haake R&D twin screw extruder allows for small trials and color match sampling. A range of pre and post extrusion equipment maximizes quality, consistency and throughput. Dehumidifying hopper dryers, along with dehumidifying and nondehumidifying tray oven dryers ensure materials are properly prepared prior to melt blending. Sophisticated material blending and feeding technologies include high intensity pre-mixers, deagllomerating V-blenders, Loss-in- Weight pellet and powder feeders, and liquid feeders. Post extrusion technologies such as strand and underwater pelletizing, sifters, classifiers and cross tumblers ensure finished materials are consistent throughout the lot and from lot-to-lot.
Our material testing capabilities include viscosity, melt flow, FTIR, capillary rheometer, specific gravity, bulk density, tensile, elongation, flexural modulus, ash testing, durometers and more.
