![Polystone® M Soft (UHMW-PE)]( "Polystone® M Soft (UHMW-PE)")
Polystone® M Soft (UHMW-PE)
Polystone® M Soft (UHMW-PE) - Röchling Engineering Plastics has developed the new surface-friendly material
Polystone® M Soft for conveying sensitive materials.
Many industries including beverage, packaging, pharmaceutical and cosmetics
utilize elaborate plastic containers and delicate glass bottles. Scratches and
other types of surface damage can be a challenging problem when handling these
products during the manufacturing processes. For instance, scratches on clear
PET mineral water bottles can easily result from the materials they contact
during the stages of filling, capping and packaging. That is precisely where
Polystone® M Soft is put to use.
Polystone® M Soft has an optimized formulation for
particularly gentle sliding properties and outstanding
abrasion resistance. The friction between the product
being conveyed and the material that it comes into contact
with is kept to a minimum. This sophisticated engineering
plastic ensures a rapid and smooth conveying process and
at the same time gently handles the conveyed products.

![PTFE - Carbon-Filled]( "PTFE - Carbon-Filled")
PTFE - Carbon-Filled
Carbon-Filled PTFE was developed for its mechanical properties. The two basic materials used in these compounds, by themselves, are very questionable.
PTFE has good frictional properties including low wear rates and good elasticity. The carbon filler is brittle and has low wear properties. Both fail at high loads and increased
velocities. When both elements are formulated and properly blended together, they become an
extremely good material for use as seals and rings in the reciprocating compressor industry.
The properties increase several hundred times. Wear resistance is changed dramatically
compared to Virgin PTFE. The type and percentage of carbon is critical to material
performance. Carbon filled has a higher percentage of filler than any other PTFE blend.
Therefore the two materials must be similiar in size to prevent voids in the molded billet. For
optimum wear properties, the filler percentage is also important. Lower percentages are
easier to machine but do not perform as well in service. AVA56 PTFE material, is designed
for optimum wear properties in all suitable applications.
The molding cycle is also important to provide proper pysical properties. At higher molding
pressures the material has higher density and more filler is required. Not all carbon filled
PTFE is of the same quality.
