Multiwall
PC Multi-wall sheets are good insulators for sound and heat energies. PC hollow sheets have very good optical quality and are easy to handle and show an exceptional low and high temperature performance, from -40oC up to +120oC. They have excellent mechanical, thermal and electrical properties. Their impact strength is 250 times a more than glass & are almost unbreakable. They have good formability and their recycling is easy. As they are inflammable, they have found wide applications in the construction Industry. PC hollow sheets are resistant to most of the common solvents and chemicals.
