Zinc oxide is used as the main activator along with stearic acid in the vast majority of rubber formulations today. However, some have considered zinc oxide as just another industrial chemical. This paper compares different grades of zinc oxide in critical rubber compounds.
One of the biggest issues facing the automotive and transportation sectors is what to do with scrap tires. And while major strides were made in developing sustainable practices for recycling scrap tires, most of these do not add value, according to Ben Chouchaoui of Windsor Industrial Development Laboratory Inc.
Authors from Akron Rubber Development Laboratory and Akron Polymer Solutions analyze the role of compound variables on vibration isolators. In two parts, this Technical Notebook looks at the effect of polymer type and Prohene on vibration isolators.
Electric vehicles and low-emission hybrid cars are driving the transformation of mobility. This means it’s time to learn more about new materials, which can help target the rolling of high-tech tires into carbon neutrality and ultimately into a CO2 emission-free future.
Silicones are well known to medical device users and suppliers as they have been used for decades for medical applications, particularly for implantations. PIB rubbers are less well known, but in laboratory studies appear to have strong advantages over silicones.
Over the last three decades, the rubber process analyzer has evolved as the processability test instrument of choice for measuring and solving many rubber factory problems. Now there are several different RPA ASTM International methods that are used routinely by the rubber industry to measure the quality-of-mix of different rubber compounds for predictions of downstream processability differences.

While passenger tire retreading has fallen out of economic favor since World War II, commercial vehicles still use retreads in large percentages. Craig Norton of Bridgestone's Bandag talks about how retreading is the perfect example of making sustainability sustainable.
Precipitated silicas have been used as a reinforcing filler in rubber formulations for more than 80 years. And it's use has only increased. Ken Bates of the Polymer Solutions Group tells us all about it.
Being a rugged instrument, the DMYO-V can be used on the shop floor to ascertain that rubber compounds meet mechanical specifications, including crosslink density, tan delta, storage, and loss modulus and dynamic modulus, among others.
