WebDetermination of the Glass Transition by means of Dilatometry DIL measurement on a natural rubber material between -120°C and 20°C at a heating rate of 3 K/min in helium atmosphere. the sample length amounted to 2 mm. The extrapolated onset temperature of -62°C corresponds to the glass transition (Tg). WebApr 8, 2024 · 1.Introduction. Acrylonitrile-butadiene rubber (ABR) (generally known as Nitrile rubber) is widely used as gaskets, hoses, and seals in aero engines, helicopters, fuel/hydraulic systems of aircraft and rockets due to its high stability within the temperature range of –40 °C to +108 °C, good abrasion and tear resistance [1], [2], [3], [4].ABR is an …
