This document provides product information for two high performance greases - MOLYKOTE® PG 30 L and MOLYKOTE® EM 30 LG. The greases contain no lead or nickel and have a high load carrying capacity, making them suitable for lubricating plastic, plastic, plastic/metal, and rubber/metal combinations with medium to heavy loads and low to medium speeds. The document lists typical properties such as consistency, density, service temperature range, and test results for properties like oxidation resistance, corrosion protection, and oil separation. Usage instructions and limitations, packaging, storage, and warranty information are also provided.
