RIB DESIGN GUIDELINES
The minimum distance ribs should be spaced is
three times the nominal wall thickness (3W) .
Solvent
Solvents soften surfaces of plastic (plastic
must be soluble)—best for amorphous or
low crystalline plastics, such as ABS, acrylic,
cellulosic, PC, PS, PPO, and vinyls .

These customizable formulations can replace traditional materials such as FR PC/ABS, FR PC/PET and FR COPE, offer improved chemical resistance to common disinfectants, achieve a UL 94 V-0 at 1.5 & V-1 at 0.75 flame rating when necessary, and can often be molded in existing PC/ABS tooling.
Chemically resistant replacement for FR PC/ABS, FR PC/PET & FR COPE providing UL 94 Yellow Card V-0 flame rating at 1.5 mm, V-1 at 0.75 mm thicknesses for a broad color spectrum
Outperforms FR PC/ABS, FR PC/PET and FR COPE in resistance to common disinfectants
