We’re pleased to offer you an overview of our broad line of Engineering and High Performance Plastics - available for a wide range of applications. Penn Fibre is the largest extruder of engineering and high performance thermoplastics in North America. We have been in business since 1937, and started as a stamping operation in Greenwood Delaware.


Plastic Sheets

Today our largest business is extruded plastic sheet. The plastic sheeting materials include nylon, specialty nylons, thermoformable nylons, Delrin®, Delrin® AF acetal, PVDF, PBT, Ultem® PEI, Polysulfone, Noryl PPO, Hytrel copolyester elastomer and PEEK to name a few. We extrude these materials with a variety of modifiers for color, electrical conductivity (ESD), flame retardancy, UV or heat resistance, and reinforcing fibers. The plastic sheet business is largely stock and inventoried sheets made to standard sizes.

Strips & Coils

Rolls of Plastic

In addition to plastic sheet we make a wide variety of materials into stock master coils which are cut to customer specified width and shipped as rolls of plastic sheet. This business is completely custom produced (made to order), and typically ships 7-10 days from order.

Custom Parts

Custom Parts

Finally, Penn Fibre continues stamping custom parts from all sort of plastic sheet as well as from vulcanized Fibre, Mylar® PET films, UHMWPE, High Impact Polystyrene, PTFE, Phenolics, and much more.

So, whether your requirements call for thin gauge rolls of plastic sheet slit to custom widths, flat plastic sheet, or washers and stamped parts, Penn Fibre is your source. We, are ISO 9001 certified, have relatively short minimum run requirements for custom sheet, and experience with extruding more resins then any other producer in North America.
