· Easy processing.
· No post cure or with slight post cure.
· Good compromise between tear strength and compression set.
· Good heat stability up to 225°C.
· Bright colours easily obtained (unfilled).
· Good level of filler acceptance to obtain higher durometer compound (up to 90).
· Blendable with master-batches from the “Mix and Fix” range.

BLUESIL MF 680 U is recommended for moulding, injection moulding and extrusion of articles with good mechanical properties (especially low compression set and high resilience).
For extrusion applications, depending on processing conditions and geometry of the profile : the addition of 0,5 parts of BLUESIL ADD 916 improves the visual quality of profiles after vulcanization.
