Elastomer moulded parts
These parts are usually supplied in VHDS (very high density silicone) rubber and the full reference should include:
– the letter S,
– the appropriate grade which corresponds:
– to the youngs modulus of the rubber under static compression in accordance with ASTM D945 (ref. 33 to 77),
– or to the stiffness measured on a part (ref. 16 to 25).
