The IRHD dead load and type A durometer instruments were used to test the standard Wallace micro samples (2 mm thick).
In contrast, the standard dead load blocks of 8 mm thick, when tested on the micro IRHD and the type M durometer instruments, tended to give approximately the same results as the dead load IRHD and type A durometer instruments.
Various thinner samples were used with the micro instruments.
In general, the resulting curves on the graphs were flatter when testing the o-rings on a micro IRHD instrument than on the type M durometer.
Users say Micro Tuff minimizes polymer build-up, plate-out, and burning and reduces the frequency of tool cleanings by at least 50% with such resins as PVC, CPVC, PS, acrylic, PTFE, and PE.
In another case, a CPVC pipe maker cut its chrome-plating costs from $37,000/yr to $7000/yr after applying Micro Tuff to its pipe tooling and adapters, Kupper says.
- offer Micro Tuff coating as an option on their dies.
Production Components has applied Micro Tuff to nearly 60% of its dies in the last 18 months.
