What is Compounding? 

UNINKO compounds a wide range of engineering thermoplastics. Compounding is a process of melt blending plastics with other additives. This process changes the physical, thermal, electrical or aesthetic characteristics of the plastic. The final product is called a compound or composite.

Compounding starts with a base resin or polymer. UNINKO has experience with more than 60+ resins systems, each of which has unique characteristics that make it suitable for use in certain applications.

By incorporating an extensive range of additives, fillers, and reinforcers, a wide range of properties can be achieved in conductivity, flame retardance, wear resistance, structural, and precolored. Our engineers independently select the additives based on your unique performance criteria. For example, glass fibers can be added at various levels to increase stiffness in a resin that is more flexible than desired.

Compounding is done in several steps. Resin and additive(s) are fed through an extruder where they are combined. The melted compound exits the extruder in strands about the diameter of yarn. These strands are cooled and cut into pellets. The pellets are thoroughly inspected and must pass 10 internal quality checks before being delivered to customers for use in injection molding or sheets/rods extrusion.

Specialty compounding is an exacting, yet creative, science. UNINKO formulates a wide range of materials, resulting in a unique compound that solves your application problems and delivers the solution with the shortest lead times in the industry.
