MOLY FILLER ADDITIVE GROWING IN POPULARITY
Plastics Manufacturers make moly filled plastics by adding Molybdenum Disulphide (moly filler) as an additive to their compounds. Demand for moly filler is growing due to:
- Low coefficient of friction
- Abrasion and wear resistance
- Stiffness and compressive strength improvement
- Hardness improvement
- Excellent low and high temperature properties
- Impact resistance
Additionally, moly filler doesn’t attract dust, and doesn’t significantly alter electrical and chemical properties of moly filled plastics. Moreover, plastics technologists can use molybdenum disulphide to reduce the impact of other additives, such as glass fibres, on the tribology.
Due to these excellent mechanical and tribological properties, more and more plastics producers are using moly filler. In particular, many manufacturers of speciality industrial engineering thermoplastics, such as polyamides (Nylon polymers) and PTFE, now offer moly filled plastics.
MOLY FILLER AND PLASTIC COMPONENT FABRICATION
Polymer engineers process polymers and plastics to make parts, mouldings, and extruded profiles. In doing so, they employ various manufacturing techniques, such as extrusion, injection moulding, and machining. Depending on the fabrication method, manufacturers can add moly filler during compounding, or they can use moly filled plastics or masterbatch.
Many users of moly filled plastics use them for speciality applications that require precision engineering. Consequently, many specialised parts manufacturers use machining methods, including CNC machining. Moly filled thermoplastics generally have good machinery characteristics.
Due to the thermoplastic nature of the polymers, fabricators can process these materials by many standard methods, such as injection moulding, extrusion, compression moulding. For applications requiring tight tolerances, some manufacturers use injection moulding followed by machine finishing.
DOWNSTREAM USES OF MOLY FILLED PLASTICS
Industrial equipment manufacturers can reduce the weight of their products by replacing metal with moly filled plastic parts.
Consequently, moly filled plastics are used to make:
- wear pads
- racks & pinions
