Kostrate® has found success in the cosmetic market but it is suggested that customers test the contents of their product with our material prior to approving usage. If chemicals are shown to attach Kostrate® Edge then a Chemical Resistant grade may be viable.

Kostrate® has been very successful in replacing Zylar in the paper dispenser/soap dispenser industry. Kostrate® provides a cost savings in this market.
