3 Page 2 Joncryl ADR-4368-C is a patented, multi-functional reactive polymer specifically formulated with reduced residual content for specific food applications in PLA and PET It is a polymeric chain extender that reacts to increase melt viscosity and (intrinsic viscosity).

4 Joncryl ADR-4368-C can be used during processing to increase the melt strength of PLA and polyesters. This is useful in extrusion applications such as film, sheet, foam and blow molding. It can also be used directly in the polymerization process. Joncryl ADR-4368-C has clearance under FDA Food Contact Notifications 429 and 545. See BASF regulatory bulletin. Joncryl ADR-4368-C has clearance under the European Economic Community s food contact rule, Commission Directive 2002/72/EC or Plastic Directive. Joncryl ADR-4368-C contains glycidyl methacrylate GMA which is subject to a QMT of 5 mg/kg for the final product.

It is offered as a flake or a sugar size powder. Joncryl ADR-4368-C can also be melted and handled as a hot liquid. Form Particle Size 1/ Physical Characteristics Description Flake ADR-4368-C mm mean <2% (w/w) smaller than mm Efficient for dry blending with cold plastics pellets of flake, or for separate feed operations Sugar size ADR-4368-CS mean <10% (w/w) smaller than mm Recommended for dry-blending operations with cold or hot (post dryer) solid plastic.

Particle size distribution may shift toward smaller particle sizes with handling due to the brittle nature of this additive. 2. Joncryl ADR-4368-C can be melted on-site to form a medium viscosity liquid in conventional steam or hot oil heated tanks. 25-Jan-08 Joncryl ADR- 4368c Page

9 4 3. METHODS OF DOSAGE Operation Procedure a) Flake or sugar size can be dry-blended with pre-dried and cold (<40 C) plastic pellets or flakes with the aid of low shear mixer such as tumble mixer or conical mixer. 1. Dry-blending b) All solid forms of Joncryl ADR-4368-C can be mixed with other materials in a high shear mixer such as a Henschell mixer below 50 C.

10 Cold mixing may be aided with of Joncryl ADP-1200, acrylic plasticizer. a) Dry-blends prepared as in (1) can be volumetrically, gravimetrically or flood fed directly into the mixing zone of the extruder (see temperature recommendations in the Processing Conditions in Section 4.) b) Gravimetric feed metering systems can be used to feed any solid product form in a parallel stream with the plastic directly into the feeding zone of the extruder. Belt and disc feeders are particularly recommended for the flake form. Single Screw Feeders Clearance of 3 to 5 mm ( in) between the screw and the tube recommended.
