Cancarb Limited has published a Technical Bulletin that describes the advantages of incorporating Thermax® Thermal Carbon Black in various formulations of polystyrene (PS) foam. The study documents the dispersion and processing benefits of Thermax® and uses similar expansion, density, open-cell content, and compression properties as the control. Adding 4 wt.% thermal black resulted in a ~ 3% reduction in thermal conductivity and a ~ 14% reduction in thermal effusivity.

Cancarb Limited has published a Technical Bulletin that shows how formulating EPDM rubber with Thermax® N990 improves compound dispersion, decreases mixing energy, reduces compound viscosity, and supports potential cost reductions.

RDC S.r.l., a global supplier of pre-dispersed chemicals and additives, has revised its product brochure for the rubber and thermoplastic industries. The highlights include a new section about the company’s Premix® Specialties and new pages about its Veaflame flame suppressors and Films and Bags for Chemical Pre-Dosing. There are several other changes as well.

Cancarb Limited has published a Tensile Strength Distribution Technical Bulletin that shows how formulating nitrile butadiene rubber (NBR) with Thermax® N990 improves dispersion quality and supports potential cost reductions. The study compared nine materials, including two Thermax® medium thermal carbon black materials, and used tensile strength distribution instead of optical instruments to evaluate dispersion quality.

Cancarb Limited has published a Technical Bulletin that shows how Thermax® N990, a medium thermal carbon black, improves compounding and boosts the performance of EPDM gaskets for polymer electrolyte membrane (PEM) fuel cells. The benefits of adding Thermax® N990 to EPDM include good compression set, low-temperature flexibility, and increased resistance to heat and chemicals.

Alpha Technologies has published a study about rubber process analyzers (RPA), viscoelastic properties, and mix quality in a recent Technical Notebook for Rubber News. Authors John Dick and Richard Hanzlik compare the relative advantages of various viscoelastic properties that an RPA can measure. This article is the first in a two-part series by the authors.

RDAbbott recently hosted a webinar titled “The ABCs of RDC: Rubber Dispersion Chemicals.” This 25-minute presentation about leading products and new solutions from RDC S.r.l. was livestreamed on March 30, 2023.

Join RDAbbott on Thursday, March 30, 2023, from 10:00 – 11:00 AM (ET) for “The ABCs of RDC: Rubber Dispersion Chemicals,” a free webinar about leading products and new solutions from RDC S.r.l., a global supplier of pre-dispersed chemicals and additives. This live event will also highlight VEAFLAME, a new halogen-free flame retardant that provides compounders with a safer and healthier alternative to antimony trioxide and borate salts.

RDAbbott recently hosted a webinar titled “Benefits of Thermax® N990 to Rubber Compounding.” This 53-minute presentation about Cancarb Thermax® N990 thermal carbon black was livestreamed on April 28, 2022. It is part of RDAbbott’s 2022 Webinar Series, which provided technical insights and processing recommendations from its supplier partners.

RDAbbott Canada, Ltd. will showcase materials and technologies for the mining industry at this year’s CIM Convention & EXPO in booth #1705. CIM, the Canadian Institute of Mining, Metallurgy and Petroleum, is returning to in-person events and hosting CIM EXPO, Canada’s premier mining trade show, at the Vancouver Convention Centre (West Building) in Vancouver, British Columbia, Canada, from May 1 to 3, 2022.
