If the vulcanization temperature is raised when silicone rubber products are being moulded, both the vulcanization time and efficiency can be effectively increased. As a result, many vulcanization moulding experts will begin their processes as soon as the temperature rises in order to speed up the moulding of custom silicone rubber keypads. Sometimes it does shorten the cure period, but other times it is counterproductive and causes a lot of numbness and rupture rather than enhancing productivity.

Natural rubber (NR) vulcanization temperature recommendations: the most suitable range is 140 to 150 °C, with a maximum temperature of 160 °C.

Butadiene rubber (BR), isoprene rubber (IR), and neoprene rubber (CR) should be vulcanized at temperatures between 150 and 160 °C, with the peak temperature not surpassing 170 °C.

The suggested vulcanization temperature for SBR and NBR is over 150°C, with the peak temperature not exceeding 190°C.

NextGen’s Oscillating / Automatic Disc Rheometer (ODR) temperature display resolution is 0.01°C.
