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.

Electrical resistivity is an important property for various EPDM applications, such as wire and cable, battery and fuel cell gaskets, and automotive profiles. To achieve the specified electrical resistivity values in these applications, it is necessary to replace smaller particle size furnace blacks with mineral fillers and/or larger particle size carbon blacks. This 47-minute presentation highlights the results of Cancarb’s technical study that compared blends of hard clay, Thermax® N990, and N550, and evaluated how the size, structure, and surface chemistry of these filler systems impact the insulative and conductive behaviors of the EPDM compounds.

ITW Pro Brands is promoting a new mold release agent, DiamondKote™ DKW-4185, for faster and easier mold cleaning. This water-based, semi-permanent product releases polyacrylate rubber, butyl rubber, natural rubber, SBR, EPDM, and most sulfur-cured elastomers from mold surfaces. DiamondKote™ DKW-4185 can also be used with FKM that is amine-cured or bisphenol-cured, and with rubber-to-metal bonded parts.

Dow has launched a new series of selective adhesion LSR products for the mobility and transportation industry. SILASTIC™ SA 994X LSRs are primer-less, self-adhesive, and available in standard and self-lubricating versions with a one-to-one mix ratio for two-component injection molding with thermoplastic substrates. These new LSR materials were specifically developed to target adhesion to polybutylene terephthalates (PBT) and polyamides (PA).

Cancarb has launched Thermax® N990CG, a low PAH grade of thermal carbon black that gives customers the ability to minimize the amount of polycyclic aromatic hydrocarbons (PAH) in their products without sacrificing quality and performance.

DiamondKote™ DKW-4168 is a mold release agent from ITW Pro Brands that was developed to meet the growing needs of FKM seal and gasket manufacturers who serve the automotive supply industry. In addition to fluorocarbon-based fluoroelastomers, this versatile mold release can be used with silicones, peroxide-cured EPDMs, and polyacrylates. This demonstration video from ITW Pro Brands shows how DiamondKote™ DKW-4168 is packaged, applied, and used.

On Tuesday, May 4, 2021, from 11:00 AM – 12:00 PM (ET) the Ontario and Quebec Rubber Groups will host a free webinar titled, “Elastomer Sealing Performance in Hydrogen Fuel Cells.” In this live webinar, ARLANXEO Polymer Scientist Jake Rawski will highlight elastomer sealing performance advancements using Thermax® N990 Carbon Black and X_Butyl® Bromobutyl designed for hydrogen fuel system technologies.

Parker LORD recently hosted a webinar on “Transforming Regular LSR into Self-Bonding LSR.” We wanted to make sure you have access to this insightful presentation.

Parker LORD is hosting a webinar on Wednesday, September 23rd at 2:00 PM (ET) to introduce its introduce its revolutionary adhesion additive patent-pending technology, Chemlok® 3Stream (3S), that transforms regular liquid silicone rubber (LSR) into self-bonding LSR.
