 PSG has developed a lubricity additive for several of our resin families.  These include: Kostrate ® Sizzle, PSG Edge, EsterGlas and Kostrate® Edge.

Our lubricity concentrates, when added to the base resin, do not wear off or dissipate.  They do not cause "gumming" or "stickiness" and it maintains clarity.

Once added to a thermoplastic, it becomes part of the thermoplastic and remains as long as the thermoplastic

The molecular weight of the lubricity is lower than the base resin.  Therefore, it continues "bloom" for the life of the part. This additive lowers the coefficient of friction which is especially valuable to P.O.P. applications.

In a recent comparison between silicone ("siloxane") our lubricity concentrate came out superior.  The silicone, although immediately reduced the coefficient of friction, ours after being allowed to "bloom" for 24 hours produced a same or better result.  And if the surface of the Silone part is "wiped" it does not offer the same recovery result (it was worsened) and eventually the silicone dissipated.  Our results were static for the life of the part.

In addition to the practical uses of this additive, there are aesthetic purposes to consider as well.  The lubricity provides a nice "hand feel", making even a commodity GPPS feel like a higher quality resin.  It gives a very slight enhancement to chemical resistance, and scratch resistance.  It will cause parts t release from the mold better as well.

In terms of cost, the scrap rate is a molder's first consideration.  If the lubricity is added at 1/2- 1% which it most often is, and this is a cost of .03- .07 per pound of material, is the current scrap rate high enough to justify the addition?? In most cases, it is.  And will your customer appreciate the added benefits of a better "feeling" part?  And again, for P.O.P., the ability to have a product more freely slide in a pusher system with no loss of performance for the life of the part.

For many applications, our lubricity is a practical solution for many issues and at a savings!
