2 ADR- 4368 Page 2 Joncryl ADR- 4368 is a multi-functional reactive polymer designed to reverse the degradation of PET, polycarbonate, nylon and other condensation polymers. It is a polymeric coupling agent that reacts with degraded polymers to restore the original molecular weight as well as (intrinsic viscosity) and melt viscosity. This means low quality recycle can be upgraded or that good quality recycle can be treated more robustly.

3 Joncryl ADR- 4368 can be used during processing to increase the melt strength of polyesters or polyamides (nylons). This is useful in extrusion applications such as film, sheet, tape fiber, thermoforming and blow molding. Joncryl ADR- 4368 has clearance under the European Economic Community s food contact rule, Commission Directive 2002/72/EC or Plastic Directive. Joncryl ADR- 4368 contains glycidyl methacrylate GMA which is subject to a QMT of 5 mg/kg for the final product. For more detailed information on national level, please contact your BASF representative. 1. PRODUCT FORM Joncryl ADR- 4368 is a solid oligomeric chain extender. It is offered as flake, a sugar size powder. Joncryl ADR- 4368 can also be melted and handled as a hot liquid. Form Particle Size 1/ Physical Characteristics Description Flake ADR- 4368 -F 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 -S mean <10% (w/w) smaller than mm Recommended for dry-blending operations with cold or hot (post dryer)solid plastic.

4 Requires proper dust handling equipment. Liquid 2, melted form of ADR- 4368 Temp C Viscosity Poise 100 18600 150 100 200 250 The liquid may be pumped directly into feed zone or downstream liquid port. 1. Particle size distribution may shift toward smaller particle sizes with handling due to the brittle nature of this additive. 2. Joncryl ADR- 4368 can be melted on-site to form a medium viscosity liquid in conventional steam or hot oil heated tanks. 25-Jan-08 Joncryl ADR- 4368 Page 3 2.

5 RECOMMENDED DOSAGE FOR Joncryl ADR- 4368 With deep understanding that every chain extension problem is unique, our Technical Service experts will help you define the right dosage for your specific system. The guide below may be used as a reference for typical ranges of dosage of Joncryl chain extenders. Plastic Application Recommended Dosage (% w/w) Fiber (staple & filament) to Injection/blow molding bottle to Sheet, tape & profile to Film & bottle blow molding to Strapping to Compatibilization PET/PA-nylon to Polyesters (PET) Foam to Injection Molding to Fibers to Profile extrusion to Sheet & film to Branching to Polyesters (PETG, PBT,PLA, others) Foam to Injection molding to Profile extrusion to Sheet, film & tape to Branching to Polyamides (nylon, PA 6 & 6,6, other) Compatibilization polyester/PA-nylon to Injection molding to Hydrolytic stabilization to Sheet & film to Polycarbonates (PC) Branching to Melt strength to Other condensation thermoplastics (TPU, POM)

6 Stabilization to 25-Jan-08 Joncryl ADR- 4368 Page 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.

7 1. Dry-blending b) All solid forms of Joncryl ADR- 4368 can be mixed with other materials in a high shear mixer such as a Henschell mixer below 50 C. 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. Twin-Screw Feeders Non-intermeshing spiral screw with 6 mm ( in) clearance between the screw and the tube recommended.

8 Eliminate agglomeration at the throat or feed zone by maintaining tube temperature below 80 C. c) Volumetric Feeders: Well calibrated feeders with variation of less than are recommended. Clearance of 3 to 5 mm ( in) between the screw and tube is also required to reduce fines. Eliminate agglomeration at the throat or feed zone by maintaining tube temperature below 80 C. d) Side feed systems and other types of forced dosing extruders may be employed with all solid product forms, except for fine powder, to feed the products downstream. Residence time recommendations are given below in reference to downstream feeds. e) Direct gravimetric/volumetric addition of the chain extender in any form to the plastic melt may be carried out through any suitable downstream venting or degassing port. 2. Addition of Joncryl ADR- 4368 on a single-screw extruder, twin-screw extruder or kneader.

9 F) With the aid of a melting tank, Joncryl ADR- 4368 becomes pumpable at temperatures about 120 - 140 C. Jacketed melt tank with stirrer and temperature control up 145 C with nitrogen purge recommended. Feed between 120 - 140 C. Use continuous and positive displacement pump. Close Vent Delivery: Use pump that can deliver pressure up to 2000 psi. Injection valve with variable pressure control to deliver the additive at pressure higher than in the extruder. Pressure gauges are recommended. 25-Jan-08 Joncryl ADR- 4368 Page 5 3.

10 METHODS OF DOSAGE - Continued Operation Procedure a) Dry-blends prepared as in (1) can be volumetrically, gravimetrically or flood fed directly into the mixing zone of the injection molder (see temperature recommendations in the Operating Conditions in Section 4.) b) Flakes not recommended for direct addition to injection molding equipment. c) Volumetric Feeders: Well calibrated feeders with variation of less than are recommended. Clearance of 3 to 5 mm ( in) between the screw and tube is also required to reduce fines. Eliminate agglomeration at the throat or feed zone by maintaining temperature below 100 C for MB polymer carriers or 80 C for wax Addition during injection molding and combined injection-blow molding operations. d) With the aid of a melting tank, Joncryl ADR- 4368 becomes pumpable at temperatures about 120 - 140 C. Jacketed melt tank with stirrer and temperature control up 145 C with nitrogen purge recommended.
