Quality Reigns at Preferred Plastics

Welcome to Preferred Plastics. We are a custom extruder of thermoplastic resins, specializing in the manufacturing of rigid, flexible, and co-extruded products for a wide range of markets worldwide. And to what do we owe our success? Largely to a knowledgeable, supportive team that works cohesively and comprehensively to give you the best engineered product at the highest possible quality.

Preferred Plastics originated in Plainwell, Michigan in 1975 as a United Technologies facility serving the automotive industry, and has transitioned into a multi-facility operation highly experienced at serving over ten diverse markets. This achievement was born from an unwavering commitment to quality, customer service, and the vision of a new owner who left the banking industry in 1994 to pursue a desire to run his own business.plastic extrusions
