POLYCRETE is a seamless urethane concrete overlay system. It's the ideal solution for commercial kitchens and service areas where a durable, seamless, waterproof, non-skid, anti-microbial surface is desirable.he disadvantage of a vinyl composite floor (VCP) is that it is susceptible to staining and denting. Furthermore, it's not a true seamless floor -- the seams in composite sheet vinyl are heat welded together. Sooner or later, in heavy traffic areas, these seams will break, peal, or bust.
Polypropylene (PP) is a thermoplastic. It is a linear structure based on the monomer CnH2n. It is manufactured from propylene gas in presence of a catalyst such as titanium chloride.eside PP is a by-product of oil refining processes. Most polypropylene used is highly crystalline and geometrically regular (i.e. isotactic) opposite to amorphous thermoplastics, such as polystyrene, PVC, polyamide, etc., which radicals are placed radomly (i.e. atactic).
