Custom Plastic Solutions & Consulting for Diverse Applications


Mitsui Plastics, Inc. provides a multitude of material solutions to the plastic and chemical industries. We offer a full line of engineering- and commodity-grade resins and compounds as well as polymer additives, minerals and semi-finished goods. In addition to offering standard or “off-the-shelf” products, we have the capability to develop and/or supply custom materials based on your unique requirements. Contact us for custom materials when:

  • You are having trouble sourcing a particular product.
  • You need a more competitive supply source.
  • Your current product no longer meets your requirements.
  • Your current product does not meet your companies sustainability goals.

At Mitsui Plastics, we maintain good working relationships with many companies that perform custom formulation. In fact, we know which companies are skilled at formulating certain compounds, which companies excel in development or color, which companies offer products at lower prices and so on. What does this mean for our customers? It means that, rather than trying to sell you a product because we have it in inventory, we will help you design a solution to fit your particular needs. Customer service doesn’t get better than this!
