Effect of two-phase crosslinking network on properties of acrylate rubber/hydrogenated nitrile rubber vulcanizates

open access: yesHecheng xiangjiao gongye
The two-phase crosslinking network state of acrylate rubber(ACM)/hydrogenated nitrile rubber (HNBR) vulcanizates was regulated by adjusting the amount of TRA using trithiocyanuric acid (TCY)/tetrasulfide bispentamethylene thiuram (TRA) as vulcanization ...

Precision in Rubber Seal Lifetime Prediction: The Critical Role of Aspect Ratio

open access: yesPolymer Engineering &Science, Volume 65, Issue 12, Page 6781-6797, December 2025.
This study examines how specimen geometry affects rubber seal aging predictions. We examine NBR and EPDM samples with varying aspect ratios (AR) under thermo‐oxidative conditions. Analysis includes indentation modulus, hardness, crosslink density, and calorimetric analyses. Results reveal how aspect ratio influences aging behavior.

Recycling Waste Rubber Into Single‐Walled Carbon Nanotubes: Narrow Chirality Distribution and Hydrogen Byproduct

open access: yesCarbon Neutralization, Volume 4, Issue 5, September 2025.
A magnesia‐supported cobalt catalyst is designed to effectively upcycle waste rubbers and tires, producing high‐quality single‐walled carbon nanotubes with a narrow chirality distribution and hydrogen. This approach is applicable to six different types of rubber products and real‐world tires, offering a new pathway for waste rubber recycling and ...

Ageing of HNBR, EPDM and FKM O-rings

open access: yes, 2016
HNBR, EPDM and FKM O-rings were aged uncompressed and compressed at 75 °C, 100 °C, 125 °C and 150 °C for up to 1 year. HNBR exhibited the strongest ageing effects with high increases of hardness and glass transition temperature.

Poly(Alkylene Ether)s With Nitrile Pendent Groups

open access: yesJournal of Polymer Science, Volume 63, Issue 13, Page 2745-2756, 1 July 2025.
Oxirane monomers were synthesized and polymerized using the Vanderberg initiator to obtain poly(alkylene ether) nitrile polymers. These polymers have a range of thermal properties and stabilities, providing potential alternatives to nitrile butadiene rubber (NBR) and hydrogenated NBR (HNBR).
