This tool, designed for use with molded parts up to one-quarter-inch thick, allows quick-cure conversions over a wide temperature range.

It is based on the time-temperature relationship in the vulcanization process that says when vulcanization temperature rises, cure time decreases, and when the vulcanization temperature falls, cure time increases.

Using the Fahrenheit scale as the default, this tool shows the temperature coefficient of vulcanization of 1.5 per 10 degrees F, or using the Celcius scale, a temperature coefficient of vulcanization of 2 per every 10 degrees C.
