Molykote G-4500 FM is high-performance greases that combine the benefits of wide operating-temperature range and broad compatibility with varied materials. All are thickened with an aluminum complex and contain white solid lubricants. The white appearance helps visual inspection in sanitary environments and supports quality control in food and beverage, pharmaceutical and packaging plants.

• Wide Temperature Range - Molykote G-4500 FM provides effective lubrication from roughly minus forty degrees to one hundred fifty degrees Celsius, allowing a single product to cover most start up and running conditions in processing plants. 

  
  

• Oxidation Stability - The synthetic PAO base oil and aluminium complex thickener deliver strong resistance to oxidative degradation under continuous high temperature operation. Bench ageing tests at elevated temperatures show only moderate increases in viscosity and minimal sludge formation, that the grease preserves its lubricating film and does not quickly form hard deposits. 

  
  

• Moisture Resistance - Molykote G-4500 FM maintains its lubricating properties even when exposed to water wash, spray and high humidity, conditions that are common in hygienic processing environments. The grease also helps protect metal against corrosion initiated by residual moisture, supporting reliable operation between cleaning cycles and reducing the likelihood of premature bearing failure caused by rust and inadequate lubrication.

  
  

• Material Compatibility - The formulation is compatible with many plastics, elastomers and sealing materials commonly used in food and pharmaceutical machinery. Testing with polymer cages, housing materials and seals shows minimal changes in hardness, volume or mechanical strength after prolonged contact with the grease at representative service temperatures.

  
  

• Low Volatility - Low evaporation rates at high service temperatures help Molykote G-4500 FM retain base oil within the thickener matrix, preserving the thickness and integrity of the lubricating film. This characteristic is useful in enclosed bearings and gearboxes where replenishment intervals are long, as it reduces the risk of lubricant drying or leaving deposits that would interfere with motion. 

  
  

• Food Grade Assurance - Molykote G-4500 FM is formulated to meet stringent food grade requirements so that it can be used in applications where incidental contact with foodstuffs, pharmaceuticals or their packaging might occur. The choice of base oil, thickener and additive system is made to comply with recognised food industry guidelines while still providing the mechanical protection expected from a high performance grease. 

• Food Processing - In food and beverage processing equipment, Molykote G-4500 FM is used to lubricate conveyor bearings, filler mechanisms, mixers and chains that operate near open product or packaging materials. The grease’s food grade status and white appearance support hazard analysis procedures and make visual inspection easier after cleaning.

  
  

• Pharmaceutical Lines - The grease performs well in pharmaceutical manufacturing where cleanliness and control of contaminants are critical. It is applied to bearings, indexing tables, capsule handling mechanisms and small gear drives within blenders and coating equipment. The combination of broad temperature capability and chemical stability allows it to withstand sterilisation temperatures and cleaning regimes used in these facilities. 

  
  

• Packaging Machinery - Molykote G-4500 FM is suitable for high speed packaging equipment such as cartoners, form fill seal machines and labelling systems that experience intermittent loads and rapid cycling. Bearings and gears lubricated with this grease show low friction and consistent motion even at high operating speeds, which contributes to accurate indexing and reduced vibration. 

  
  

• Hygienic Industrial Equipment - The grease is also used in other industrial equipment installed in hygienic or clean environments, for example in dairies, bottled water plants and facilities producing sensitive ingredients. Pumps, agitators, fans and auxiliary drives benefit from the wide temperature range and resistance to water ingress.
