Proteus® LF PP (Lay Flat Polypropylene) is a proprietary Stable Machine Grade (SMG) formulated homopolymer sheet that exhibits superior dimensional stability and flatness after aggressive fabrication. Proteus® LF PP has excellent chemical and moisture resistance and is FDA and USDA compliant.

Proteus® LF PP was designed to target applications where standard PP plate and sheet products cannot hold dimensional stability tolerances specified. Ultimately Proteus® LF PP will allow for faster cycle times, increase unmanned machine hours and eliminate costly secondary part finishing operations ultimately resulting in lower part cost.
