Figure 4® RUBBER-BLK 10 is a hard rubber-like black resin (Shore 59D/97A) with high tear strength and slow rebound, suited to grips, handles, bumpers, strain relief, and overmolds, though it is much firmer than soft rubber.
Figure 4® RUBBER-BLK 10 is a hard, rubber-like black resin (Shore hardness 59D, 97A) with high tear strength, tensile strength of about 19–28 MPa, and about 75–80% elongation. Its rebound is slow rather than bouncy, which suits touch applications, and it is rated UL 94 HB and tested for long-term indoor and outdoor stability.
It is much firmer than soft rubber, so it isn’t a substitute for soft seals or gaskets.
Figure 4® RUBBER-BLK 10 is well suited to grips, handles, bumpers, strain-relief parts, couplings, and overmolds.
