Applications

• Increase Intrinsic Viscosity (IV) and Molecular Weight of reprocessed PET.
• Upgrades quality of PET films/sheets/tapes

Processing Conditions

• OPTIPET™ 213P is a fine powder.
• It should be preferably fed into the extruder through a separate feeder.
• The chain extension reaction occurs at temperature around 240°C to 240°C, which is normal for most PET processing.
• A residence time of 1-2 minutes in the extruder is desirable.
• Dosage depends on quality of the starting material, such as I.V., end groups ratio, and the target properties after modification.
• Maximum processing temperature should not exceed 350°C.

Packaging Information

• OPTIPET™ 213P powder is supplied in pre-dried form in 20 Kg (44 lbs) PE lined, HD woven sack-laminated paper bags.
• They should be stored in cool and dry place, away from direct sunlight.

Storage & Handling

Storage and Handling Procedures

• OPTIPET™ 213P should be stored away from heat, sparks, and flame.
• It is non- hygroscopic and need not to be dried prior to use as it comes in pre dried form.
• However, to have the best properties, it should be stored in a cool, dry, and well-ventilated place.
