A study of chemical and physical changes during biaxially oriented polypropylene film production
(Walter de Gruyter, 2003)
Polypropylene films obtained during the biaxial orientation process were characterized by energy dispersive X-ray analysis (EDX), scanning electron microscopy. X-ray diffraction, differential scanning calorimetry, infrared ...
Optimisation of the effect of colemanite as a new synergistic agent in an intumescent system
An intumescent system including ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonific agent and colemanite as a synergistic agent is used to enhance flame retardancy of ...
Influence of surface modification of fillers and polymer on flammability and tensile behaviour of polypropylene-composites
An intumescent system consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonific agent and natural zeolite (clinoptilolite, Gördes II) as a synergistic agent was ...
