MultiQ Thermoplastic Sandwich-Panel Composite is designed to replace plywood in concrete shoring and formwork systems or applications prone to water and humidity. Made from polypropylene resin matrix and long glass fiber reinforcement, it can be sawed, screwed, and nailed like plywood but with less dust, and it will not splinter or swell when exposed to the environment.
