The ASTM D2520 standard is split into three parts: Part A for shorted transmission line method, Part B for waveguide cavities, and Part C for general examination. Using the test method reference from ASTM D2520 Part C, we generated repeatable data on the samples of four select formulations at the same four thicknesses, recording the average and median values for both dielectric constant (Dk) and dissipation factor (Df).

This is the reason that the ASTM Method specifies a material thickness of 0.250 inches.

Formulations can pass weathering standard ASTM G154 and AATCC 186, and fire resistance standard FMVSS302.  

We can formulate and certify your vinyl powder for end-use automotive, FDA, UL, ASTM, NSF, military or customer-specific applications.
