Impact-modified PMMA Disk
Impact-modified PMMA disks are available in 16 variations for a wide choice of different dimensions and properties. Polymethylmethacrylate is a transparent thermoplastic often used as a lightweight or shatter-resistant alternative to glass. The impact modified version has enhanced toughness and crack resistance compared to standard PMMA. Potential applications for these impact modified PMMA disks include machine parts, automotive lenses and protective eyewear. With Goodfellow's comprehensive selection, engineers can find the precise Disk specifications required for their design.
