Component - Concentrates, QMLJ2

Typically, a custom compounding plastics company purchases a "neat" natural resin from a plastics supplier and enhances that formulation by adding an additive concentrate package to produce a new product. This newly Recognized material is tested and published under the QMFZ2, Component-Plastics category.

The Component - Concentrates category, QMLJ2, will permit the Recognition of the additive concentrate package that was blended with the Recognized neat base resin to produce the newly formulated Recognized plastic. What is Recognized under the new Component - Concentrates category, QMLJ2, is the concentrate itself.

The Component-Concentrates category permits the Recognized base resin to be shipped directly to the Recognized end-product manufacturing location and the Recognized concentrate package can be shipped directly to the manufacturer as well. The two are dry-blended at the specific let-down ratio by the Recognized manufacturer and molded. It is necessary for the manufacturer to be Recognized under the Fabricated Parts, Recognized Molders, QMMY2, category.

This method of supplying the base resin permits the end-product company with an opportunity for large-scale purchasing and shipment of the base resin. The Recognized Concentrate can be ordered and shipped based on production schedules.

This also provides the plastics supplier with the capability of large-scale production runs of the base resin rather than custom compounding orders.

In publishing the Recognition for the concentrate, the Recognized concentrate package, Recognized base resin suppliers name, file number and grade designation is noted on the Recognition card. The newly formulated Recognized material designation, file number and company name is noted as well.

To ensure reproducibility of the Recognized Concentrate package, identification testing consisting of Infrared Spectroscopy (IR), Thermogravinetry (TGA) and Differential Scanning Calorimetry (DSC) testing is conducted on the Recognized Concentrate package let down into its generic carrier. Periodic testing under our Follow-Up Services program is conducted.
