Drug Delivery and Implantable Polymer Rods
Monofilament rods/fibers for drug delivery and implantable applications are available with diameters typically ranging from 0.012 to 0.2 inches (0.30 to 5 millimeters) for implants, 3D printer strands (per printer specification), woven structures and more.
Co-Extrusion of multilayered filaments can combine properties of different or same polymers to limit the drug release from a core, enhance the durability of the dosage form, or modulate drug release through a fast-dissolving outer layer and a slower releasing inner layer, as examples.
Drug Delivery and Implantable Polymer Pellets & Micro-pellets:
Foster’s extrusion shaping expertise extends to micro-pellets and traditional pellet forms, including cylindrical / strand cut and spherical cuts. These materials can then be used as implants or capsule filling, among other operations. Common micro-pellet sizes range from 0.029 to 0.047 inches (0.5 to 1.2 millimeters). Traditional pellets are typically 0.059 to 0.118 inches (1.5 to 3.0 millimeters), depending on the material and the formulation.
Drug Delivery and Implantable Polymer Films:
Drug Delivery and Implantable Polymer Tubes:
Implantable and drug delivery tubes can be made from a wide range of biocompatible polymers to meet specific application requirements, often acting as a vessel to carry an API payload or a means to increase drug releasing surface area. Single lumen, monolayer tubes are most common for implants with diameters as small as 0.0098 inches (0.25 millimeters) with wall thicknesses as small as 0.0004 inches (0.01 millimeters). Co-extruded tubes and other configurations can be developed.
