Soft-Chem - 100% Virgin PTFE Sheets

Technical Sheet

APG's soft-chem - 100% Virgin PTFE Sheets provide excellent corrosion resistance and impermeability along with superior creep resistance and sealability for use in all types of applications. A proprietary manufacturing process results in a uniform and highly fibrillated micro-structure with equal tensile strength in all directions. And its superior memory characteristics ensure that bolts remain tight, so re-torquing is not necessary.

The material's high compressibility enables it to deform under load and conform to irregularities in flange faces for a tight seal with low, minimum sealing stress. Standardizing with it also helps to reduce maintenance, simplify inventory, and save money.

Pressure/Temperature Graphs

The pressure/temperature graphs shown are the most current method of determining the suitability of a gasket material in a known environment. However, chemical compatibility must also be considered.

In area 1 the gasket material is suitable using common installment practices subject to chemical compatibility.

In area 2 appropriate measures are necessary for installation of the gasket to ensure maximum performance.

In area 3 do not install gaskets in these applications without first contacting APG for technical support service.
