Material Ultrapharma has developed the material ”Steam-Flon®” for sanitary gaskets and some other innovative products. This material is a unique blend of non-pigmented PTFE and 316L stainless steel powder. The mechanical properties of this compound are very interesting because it eliminates the cold flow problems we experience with, for example, virgin PTFE. Cold flow is the term we use for movement of plastic under permanent load/stress, a state that is used with static seals. Cold flow increases at elevated temperatures. Material of the gasket is slowly moving towards the inside of the...

Recommended Torque The Steam-Flon® gasket last longer if the correct torque is applied. Over-compression is disastrous for each gasket material, even for Steam-Flon®. We recommend to use the torque guideline as shown in the last column in the table on page 3. We came to these recommendations after testing our gaskets at 10 bar water pressure. Type-III The Steam-Flon® material is a relatively hard material and can therefore cause problems with sealing when misalignment of pipelines is eminent. We are therefore introducing a solution to fix the misalignment issue and therewith improve the...
