Natural rubber masterbatch was aged at different temperatures, and the effect of aging conditions on masterbatch, final batch, Mooney scorch and cure characteristics, and cured sample was studied.
Read MoreLatex purification methods have been developed from TK roots, adapting methods used for the guayule shrub.
Read MoreNatural rubber is an electrically insulating material, but introduction of conductive fillers like carbon based materials (carbon black, graphite, carbon nanofibers or nanotubes) or metal fillers can increase the conductivity of the resulting composite. These materials are frequently used for electromagnetic/radiofrequency interference (EMI/RFI) shielding, and laboratory and military uses.
Read MoreResearchers from North Carolina State University have demonstrated a new technique for directly printing electronic circuits onto curved and corrugated surfaces. The work paves the way for a variety of new soft electronic technologies, and researchers have used the technique to create prototype “smart” contact lenses, pressure-sensitive latex gloves, and transparent electrodes.
Read MoreContinental pursues a holistic approach to make the complex and fragmented supply chains for natural rubber more sustainable: The latest digital technologies, local involvement in the cultivation of rubber, and close cooperation with strong partners are aimed at creating more transparency along the entire value chain. “We actively take responsibility in our supply chains. Only when natural rubber is responsibly sourced, we consider it a sustainable material,” says Claus Petschick, Head of Sustainability at Continental Tires. As of today, completely seamless traceability of natural rubber is technically impossible due to the high complexity of the supply chain. With its commitment, Continental is working at full speed on a blueprint for the sustainable and responsible structuring of supply chains.
Read MoreThe origins for modern project management stem from the late 1950s, where the methodology was applied in aerospace, defense and construction. With the advent of IT (information technology), a formalized system of project management was developed and has taken a foothold in nearly every business. With the recent initiative to onshore glove manufacturing to the U.S., project management has now become a central framework for the construction, equipment validation and manufacturing initiatives which underpin U.S. based glove manufacturing capabilities.
Read MoreBridgestone plans to invest an additional $42 million to establish commercial operations, with additional investment and expansion planned toward 2030. The company will collaborate and partner with local U.S. farmers and Native American tribes to increase capacity of up to 25,000 additional acres of farmland for planting and harvesting guayule at scale. Bridgestone is targeting sustainable commercial production of guayule-derived natural rubber by the end of the decade.
Read MoreCariflex Pte. Ltd. (Cariflex), broke ground at a 6.1 hectares site in Jurong Island, Singapore. Cariflex will be constructing the world’s largest and Singapore’s first polyisoprene latex plant on this site. Driven by a strong commitment to better serve its global customers in medical and consumer products, this investment represents the largest capacity expansion in Cariflex’s existing accomplishments.
Read MoreThe federal government, particularly the Defense Logistics Agency, recently indicated that its objective is to support the annual U.S. production of 50 billion nitrile gloves to satisfy the most critical U.S. medical PPE requirement. This quantity, while seemingly significant, represents about 11% of the examination gloves produced globally, and 30% of the gloves used in the U.S.
There are more than a handful of glove companies intending to contribute to the satisfaction of this government objective. The polymer designated for the gloves will be acrylonitrile butadiene latex, or nitrile latex. To produce 50 billion gloves, it will take approximately 1.1 billion pounds of nitrile latex. The U.S. presently has limited capability to manufacture nitrile latex. Most of this latex would be manufactured in Korea, Malaysia, Italy and Brazil
The Goodyear Tire & Rubber Company announced a multi-year, multi-million-dollar program supported by the U.S. Department of Defense (DoD), the Air Force Research Lab (AFRL) and BioMADE to work with Ohio-based Farmed Materials to develop a domestic source of natural rubber from a specific species of dandelion
