PLASTICS REINFORCEMENT ALLOYS ACHIEVE MAXIMUM PERFORMANCE AND PROFIT

Micro-cermetallic alloys and nano-scale alloys are evolving in status as reinforcements for plastics.  The incorporated alloys have the potential to set higher standards of performance in more-suitable plastic composites that will produce long-lasting mechanical-parts for high-stress applications.

Combining the two alloys is a sure-fire means to exceptional strength and maximum performance.

PLASTICS REINFORCEMENT ALLOYS -- ACHIEVE MAXIMUM PERFORMANCE AND PROFIT

Maximum Performance Features: 

  • Superior Abrasion-Wear Resistance
  • Ultra-Low Coefficient of Friction
  • Sliding Durability Under Pressure
  • Solid Dimensional Stability
  • High Creep and Flex-Fatigue Resistance 

Defending mechanical parts against the rigors of industrially tough and mechanically demanding severe-service environments saves maintenance costs.  End-user profits increase due to longer part-life and extended part-replacement intervals.

PLASTICS REINFORCEMENT ALLOYS:

PPM-MaxAlloy™Series-A:  Micro-Cermetallic Particles
 
High loadings of the essential primary alloy and transition resin pre-mixed for uniform dispersion into the particulate plastic matrix range.  A fluoro-reactive diffusion-bonded nano-layer is tacked onto the slick, ball bearing-like particulate primary alloy to ensure strong coupling [interfacial interaction] between the alloy and matrix.

PPM-MaxAlloy™Series-B:  Micro-Pellet Mixtures or Blended Particulates
 
Variable loadings of Series-A with suitable loadings of nano-scale alloys plus PPM-produced ceramic or metal, oxide or nitride, or carbide and a gas-reacted transition-resin combined for melt compounding pellets and isostatic pressurization of composite machinable billets. 
    
PPM-MaxAlloy™Series-C: Encapsulated Standard Pellets 

A metallurgically-processed “sheath” of PPM-produced particulate ceramic or metal, oxide or nitride, or carbide is deposited onto plastic pellets.  They are used for compounding and for isostatic pressurization into tough, abrasion-resistant materials moulded or machined into ceramic-like mechanical-parts with “cool” near-net frictionless properties in rotational and sliding function.
