In many cases, we build our own test equipment to evaluate products and test them against each other. Why? Because reliable testing requires repeatable tests, and just handing products to people to try out isn't enough. While we test many of the products we review, for some product categories we solely use research and consumer feedback.
used in rubber formulations in concentrations of 3–8 parts per hundred rubber (phr).
