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 ...
Synergistic effect of natural zeolites on flame retardant additives
The thermal degradation and flammability of intumescent fire-retardant polypropylene matrix composites consisting of ammonium polyphosphate (APP) as an acid source and blowing agent, pentaerythritol (PER) as a carbonisation ...
Tin soaps in emulsion PVC heat stabilization
In this study, the effect of a liquid stabilizer based on organotins on PVC heat stability is investigated. Control and films with tin soap heat stabilizer Sn500K were prepared by solvent casting and they were heated at ...
Morphology, order, light transmittance, and water vapor permeability of aluminum-coated polypropylene zeolite composite films
In this study, the polypropylene-zeolite composite films having 2-6 wt % natural zeolite were coated with a thin film of aluminum (Al) by magnetron sputtering, and the contribution of the Al coating on film properties was ...
