WebBecause of PDMS's chemical stability, it is often used as a calibration fluid for this type of experiment. The shear modulus of PDMS varies with preparation conditions, and consequently dramatically varies in the range of 100 kPa to 3 MPa. The loss tangent is very low (tan δ ≪ 0.001). [11] Chemical compatibility [ edit] PDMS is hydrophobic. [7] WebStable polymer is melt-compounded, adding thermal and oxidative stabilizers and optionally lubricants and miscellaneous fillers. Fabrication [ edit] POM is supplied in a granulated form and can be formed into the desired shape by applying heat and pressure. The two most common forming methods employed are injection molding and extrusion.
