By Ann Marie Somma. Charles Goodyear’s discovery of the vulcanization of rubber—a process that allows rubber to withstand heat and cold—revolutionized the rubber industry in the mid-1800s.Automotive tires, pencil erasers, life jackets, balls, gloves, and more are all in commercial use because of Goodyear’s relentless experimentation to unlock the .
vulcanized rubber immediately after de-molding when the freshly formed rubber-to-metal bond is still at a relatively high temperature. These problems are typically encountered in the manufacture of concentric bush components in which the rubber is bonded between an outer and an inner concentric metal tube.ASTM D429 test standard determines the adhesion of rubber to rigid metal substrates. This test standard is divided into methods A through H. Common application examples that use tests in ASTM D429 are vehicle engine mounts, vehicle suspension bushings, rubber-coated metal parts, and rubber-lined tanks and containers. Most of the tests involve orthogonal tensile strength or .Paracure ZOI-52: General all-purpose zinc oxide dispersion suitable for most vulcanization applications.
