In previous Rubber World columns, I have discussed the reintroduction of the manufacture of latex gloves back into the U.S. after a 25 year absence. During those years, in Southeast Asia, there have been significant, evolutionary improvements to the equipment, processing, formulations, and the latex itself. The challenge we face is to develop a competitive, sustainable manufacturing capability in the U.S., utilizing some of the personnel who were involved in glove manufacturing years ago, and merging their experience with new ways of thinking and problem solving.Read more
Specialty Silicone Products (SSP) announced that SSP-2569-65, an EMI silicone filled with silver-copper particles, is now part of the Qualified Product List (QPL) for MIL-DTL-83528, Type A. In a July 22 letter, the Defense Logistics Agency (DLA) informed SSP that SSP-2569-65, a 65 durometer conductive elastomer for shielding and sealing, passed qualification testing and has been added to QPL MIL-DTL-83528 for specific drawings and material types.Read more
The use of soybean oil as a plasticizing agent in rubber compounds versus traditional petroleum based oils is examined.Read more
Tire lightweighting is examined, including how density of an elastomer is related to its chemical constitution, and which
monomers should be used for designing an elastomer of lower density.
Structure of the light truck radial
tire according to characteristics of aging and endurance of the tire is examined, corresponding measures are taken to improve aging endurance, and obvious improvement results are explained.
Plasticizers are one of the key components of the rubber and adhesives industries. Plasticizers are used to lower hardness, improve processability and reduce raw material costs. On the other hand, mechanical properties deteriorate with plasticizer content. In addition, plasticizers often cause changes in properties with time and staining due to volatilization or bleeding. Phthalate plasticizers and aromatic oils are or possibly will be regulated due to environmental and human health issues. Kuraray liquid rubbers (KLR) are plasticizers which are co-vulcanizable with solid rubbers. Therefore, it is very unlikely that KLR will be subject to these bleeding or volatilization issues. As a result, KLR is expected to have a growth potential as an environmentally friendly plasticizer.Read more
Avery Dennison Corporation announced the launch of the AD Maxdura tire tag, one of the most advanced embedded UHF RFID tags for the tire industry. Every year some 3 billion units are manufactured globally and RFID is increasingly being adopted by all leading tire manufacturers, Michelin for instance has announced it is fitting RFID sensor tags to all its tires by 2023 and countries such as China are looking to make its use mandatory.Read more
According to the ChemAnalyst report, “Carbon Black Market Analysis: Plant Capacity, Production, Operating Efficiency, Technology, Demand and Supply, End-User Industries, Distribution Channel, Regional Demand, 2015-2030,” the carbon black market observed a promising demand in the past five years and is predicted to reach 27.21 million tons by 2030, along with a healthy CAGR of 4.82 percent in the next ten years, owing to their applications in automobile tires, industrial rubber products, printing inks and toners, belts and hoses, paints and coatings, and others.Read more
