RAJNA-i2122 Biodegradable Toughened Compound

Applications:

Medium 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 ( 58°C) heat resistance.

 

Tipical products:

Semi-cristallized household products with >90°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 0.008% (80 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.
