Croda Polymer’s Slip Agent IncroMax 100 for PET Cuts Surface Friction by 60 Per cent

Croda Polymer’s slip agent IncroMax 100 for PET cuts surface friction by 60 Per cent. An addition to Croda Polymer Additives' Atmer series is intended to improve packing and de-nesting of PET moulded parts, reduce scratch and scuff, and reduce mould release force. Atmer 7510 is a 10 per cent concentrate of IncroMax 100, the company's slip additive for use in polyester based polymers, in a PET carrier system. The active component is claimed to reduce surface friction by up to 60 per cent.

The new slip agent can be used in PET film and sheet as well as in injection moulding, and Croda says it has no adverse effect on PET colour or clarity. According to Croda by incorporating the IncroMax in an Atmer material it has overcome problems associated with adding IncroMax 100 in its natural physical form, which is a low melting point solid.

Atmer 7510 is supplied as a free-flowing pellet which Croda says makes it easy to dose as its physical form and melting point closely match the base polymer. It can be added directly to the polymer or alongside masterbatch in conventional dosing systems.

Target applications include beverage bottles, household and cosmetic bottles, thermoformed trays and tubs, food packaging, and PET film and extruded sheet.
