Introduction

Source

The devices discussed in these papers are designed to measure some cure-dependent property, while the cure is in process and at the curing temperature. The five devices to be discussed are recent developments and have created interest among those in the rubber industry comparable to the interest generated about ten years ago in analysts with the appearance of gas Chromatographic equipment. These devices will supplant the classical method of determining curing characteristics — to cure a series of slabs for increasing time intervals, determine their stress-strain properties, and from these data deduce cure rate and other information. Much more precise information is obtainable in a simple, fast test. However, they will not displace stress-strain testing for other purposes since, as Gehman and Ogilby state, the ultimate properties of tensile strength and elongation are of considerable value and importance in most service applications of rubber. They will be used as control testing devices for monitoring production batches, for development compounding work, for research studies in many aspects of rubber technology, and are being considered for control testing in the production of carbon blacks for the rubber industry, and the synthetic rubber industry. An ad hoc committee has been set up in Committee D-11 to develop standard procedures for extracting information from the traces obtained.
