RAJNA-i1126 Biodegradable Compound

Applications:

Low viscosity product for injection moulding application. This material is able to crystallize during processing by increased mould temperature (100-120°C). This cause higher HDT temperature and opaque appearance. The quick freezing of the material cause more amorphous structure and lower ( 57°C) HDT.

Tipical products:

Semi-cristallized cutleries, cups, plates with >100°C heat resistant.

Processing:

This biodegradable polymer can be processed on most conventional injection moulding equipment. The material is stable in the molten state, provided that the drying procedures are followed.

Machine:

This polymer is good for most of conventional injection moulding machine. When you chose a machine for it, the criterion should be the minimum residence time in the barrel.

Drying:

In-line drying is recommended. A moisture content of less than 0.025% (250 ppm) is recommended to prevent viscosity degradation. Polymer is supplied in foil-lined boxes or bags dried to <400 ppm. The compound should not be exposed to atmospheric conditions after drying. Amorphous polymer must be dried below 50°C.

Food Packaging Status:

This grade of biodegradable polymer complies with Plastics Regulation 10/2011 as amended. No SML’s for the above referenced grade exist in P.R. 10/2011 as amended. In accordance with P.R.10/2011 the migration should be measured on finished articles placed into contact with the foodstuff or appropriate food simulants for a period and at a temperature which are chosen by reference to the contact conditions in actual use.
