| Raw Materials | 
Lower loading levelLower material consumption for thin-walled parts | 
Requires higher filler loading to generate desired thermal conductivity | 
| Processing | 
Faster cycle times and line speedsEasier to process thin-walled and complex shapesNo increase in wear on process toolingNo dust build-up during processing | 
Hard to process complex or thin-walled shapesHard, abrasive particles cause wear on process tooling |
