NPL Technology Applied The Aptflex F36 is a two-part mix kit version of the popular Aptflex F28 acoustic tile. It has the same acoustic properties as the tile but it suitable for casting into specific shapes or moulding around awkward surfaces.

It is supplied in a divided sachet and the contents can be mixed without exposure to the chemicals. Part A is solid at room temperature and the sachet must be warmed before use at 40 °C for at least one hour. Once the chemicals are fully mixed the formulation is stable and the material is ready for use.
