Plastics Color Corp. expands antimicrobial line

Plastics Color Corp. (PCC), a supplier of color concentrates, compounds, custom-functional masterbatches and other polymer technologies, announced an expansion of its MicroBlok line of antimicrobials for polymers. The new formulation, labeled MicroBlok Z, contains zinc compounds instead of the silver ions in the original MicroBlok.

Zinc's antimicrobial effect is derived from its ability to disrupt membrane transport by blocking the proton pump that energizes the transport mechanism. The zinc compounds within MicroBlok Z are not depleted during the inhibition process, thus the antimicrobial effect of MicroBlok Z is not diminished over time.

PCC's MicroBlok Z is custom-blended to user specifications in a wide variety of resins including TPU, PP and PE. MicroBlok Z is appropriate for virtually any molding or extrusion application where temperatures do no exceed 240oC (464oF) and can be custom-formulated to any special manufacturing process. It's an ideal inhibitor for use in products subject to high humidity such as those intended for kitchen and bath environments as well as outdoor uses including furniture and decking. Additional product uses include sponges, bath mats, wire and cable insulation, plastic gloves, scrub brushes and footwear.
