PET however, has numerous shortcomings from the perspective of an injection moulding compound. Unmodified PET is generally not useful as an injection moulding resin because of its slow crystallization rate and the tendency to embrittle upon crystallization. For these reasons, PET has not traditionally... 

The following techniques are useful for analysis and charaterization for the sizing on the fibres SEM, IR and 6PC of extracts, IGC and DMA (T ) for the fibre-matrix bond micro bond, micro failure with SEM [2], confocal laser scanning microscopy [3] DMA, flexural strength, ILSS and impact of the uni-directional composites (fixed fibre length, orientation and volume fraction distributions). After this detailed analysis, the fibres are tested in their application, which is an injection moulded compound for thermoplasts, where the microstructure (fibre length, fibre orientation and fibre-fibre distance distributions) as well as the fibre- matrix adhesion determine the mechanical properties.

Long-fibre Injection moulding compounds improved surface treatment/coupling agents use of high-performance fibres in forms more suitable for injection moulded thermoplastics. 

Cellulose acetate with a low degree of acetylation (52—54% acetic acid yield) is usually preferred for use in general purpose injection moulding compounds since increasing acetylation is accompanied by a decrease in hardness and impact strength and by an increase in the temperature required for satisfactory... 

High-acetyl cellulose acetate (56-58% acetic acid yield) has found occasional use in injection moulding compounds where improved dimensional stability is required but processing is more difficult. 

Transfer moulding compounds, injection moulding compounds, casting, potting, dip and powder coating compounds, die attach adhesives. Photoresists. 

Typical properties are listed in Table 2.8 except for injection moulding compounds, which are not considered in this book.

PPS finds uses in many heavy industrial applications, including some outside the arena of reinforced injection moulding compounds. The thermal stability and broad chemical resistance of PPS make it exceptionally well suited to service in very hostile ehemical environments. Besides moulded parts, PPS polymers find applications in fibre extmsion as well as in non-stick and chemical resistant coatings. 

Special features If production is interrupted, lower cylinder temperatures to 160-170 °C only, as cool PC adheres strongly to the cylinder wall. Cylinder, screws and nozzles must usually be thoroughly cleaned if the injection moulding compound is changed. Otherwise, dark particles may become detached from the heat-damaged surface layer upon re-starting and influence the component quality.
