Foster Compounds
The building blocks of advanced medical devices are biomedical polymers tailored to achieve specific performance properties. For over two decades, Foster Corporation has been a leading supplier of these custom medical compounds for minimally invasive devices, blending medical grade polymers with performance additives or other polymers to achieve properties specific to each medical device. Foster continues to provide medical device manufacturers with precision biomedical polymer compounds.
At the center of our biomedical polymer 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 medical polymer testing capabilities include viscosity, melt flow, FTIR, capillary rheometer, specific gravity, bulk density, tensile, elongation, flexural modulus, ash testing, durometers and more.
