Specialty Plastic Fabricators (SPF) was established in 1978. With years of experience in the field, the founders focused on manufacturing flexible -“drop-in” –  tank liners for metal finishing and chemical containment.  In a market that had been underserved for years, the company grew and expanded into other product lines, and larger facilities. Today it occupies 18,000 square feet of clean and modern industrial space where it manufactures a large variety of custom industrial plastic products. The company was founded in and remains in Mokena IL, about 35 miles southwest of Chicago. Mokena is a thriving community in a convenient location with easy access to I-80.  Industrial tank liners remain the backbone of it’s product line. However, the knowledge and experience of the owners and staff enables the company to make a large variety of electronically welded and sewn products.
