Modification of Laser Marking Ability and Properties of Polypropylene Using Silica Waste as a Filler

Polypropylene (PP) belongs to the group of polymers characterized by low susceptibility to absorption of electromagnetic radiation in the infrared range (<i>λ</i> = 1064 nm). This research consisted of assessing the possibility of using silica waste from the metallurgic industry as an ad...
