Polymer composites used to manufacturing Naturacustic® acoustic screens
(Sponsored Article)
Abstract
The useful properties of PVC-based composites intended for the production of a new type
of pro-ecological acoustic screens for use in road construction as soundproof covers for urban housing
estates, bridges and railway tracks were examined. The composites were obtained by melt mixing using
a counter-rotating twin-screw extruder. PVC-based composites are characterized by high Charpy
notch impact strength (> 12 kJ/m2), high Rockwell hardness (> 78 N/mm2), high oxygen index (50%), good
resistance to UV radiation. An important advantage of these composites is the high content of agri-food
waste (30 wt%), which makes the materials environmentally friendly.
