Preparation of natural rubber (NR)/ethylene-propylene-diene terpolymer (EPDM) blends by radiation crosslinking and its heat resistance to air aging

Fushe yanjiu yu fushe gongyi xuebao
To improve the compatibility of natural rubber (NR) and ethylene-propylene-diene terpolymer (EPDM) and enhance the resistance of NR/EPDM blends to hot air aging, radiation-vulcanized NR/EPDM blends were prepared by γ-ray radiation.

Large‐Scale Hydrogen Storage: Surface and Subsurface Challenges

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
This review examines underground hydrogen storage with emphasis on the interaction between surface facilities and subsurface reservoirs. Variable renewable hydrogen requires compression, buffering, and purification before injection, while subsurface processes influence wellhead pressure, temperature, and composition.

Cistanche tubulosa Extract Protects Cast Immobilization‐Induced Declines of Muscle Strength and Muscle Mass

Traditional &Kampo Medicine, Volume 13, Issue 1, April 2026.
ABSTRACT Aim One of the effects of Cistanche herb is described in the Chinese Pharmacopoeia as for lack of strength in muscles and bones. However, concrete evidence of this herb for muscle strength has been hardly reported. The present study aimed to clarify the effects of 30% ethanolic extract of Cistanche tubulosa fleshy stem on muscle strength and ...

Influence of Acrylonitrile Content on Processing, Morphology, Thermal Behavior, and Mechanical Properties of PA/NBR Thermoplastic Vulcanizates

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

EPDM insulation modified with vinyl triethoxysilane functionalized GO to prevent plasticizer migration in solid propellant

FirePhysChem, 2023
Excessive plasticizer migration to the insulation will have a serious impact on the safety of solid propellants. In this paper, the anti-migration EPDM insulation was prepared by introducing vinyl triethoxysilane functionalized GO (GS) as modifiers to ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

Advanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

"Irradiation aging behavior of ethylene-propylene rubber under 60Co γ-ray irradiation"

Hecheng xiangjiao gongye
The raw rubbers of ethylene-propylene rubber (EPM) and ethylene-propylene-diene rubber (EPDM) were irradiated by 60Co γ-ray. The structural evolution and degradation mechanism of EPM and EPDM under a certain γ-ray irradiation dose were analyzed and the ...

Optimizing Mechanical and Electrical Performance in EPDM Composites for Spacer Dampers: A Balanced Approach via Carbon Black Ratio and Protective Waxes

Macromolecular Materials and Engineering, Volume 311, Issue 3, March 2026.
The results show that rubber grade, carbon black type, and wax composition significantly influence the mechanical, electrical, and aging behavior of ethylene propylene diene monomer composites. Optimized formulations exhibited improved elongation at break, controlled electrical conductivity, and enhanced thermal stability, meeting the targeted ...

Influência do Sistema de Vulcanização nas Propriedades da Mistura NBR/EPDM The Influence of the Vulcanizing System on Curing, Mechanical and Ageing Properties of NBR/EPDM Blends

Polímeros, 2002
A mistura NBR/EPDM apresenta diferentes velocidades de cura, o que resulta na vulcanização heterogênea das fases, isto é, a fase NBR encontra-se em grande parte reticulada enquanto que a fase EPDM encontra-se pouco reticulada ou não-reticulada em casos ...

Mechanical, Thermal, and Morphological Properties of PA/NBR TPVs: Influence of Processing Conditions and Recyclability

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...
