Flexible back of HNBR-proofed aramid/glass fabric, with lip of 80 IRHD hydrogenated nitrile (HNBR).
Under-lip temperature range
From -25°C up to +150°C constant: but note that under-lip temperature can often be substantially higher (eg, by 30°C) than fluid media temperature.
Maximum surface speed
15 m/s with Walkersele D6 design.
