Effect of the structure of ethylene-propylene-diene-graft-polystyrene graft copolymers on morphology and mechanical properties of SAN/EPDM blends

open access: yeseXPRESS Polymer Letters, 2007
Ethylene-propylene-diene-graft-polystyrene (EPDM-g-PS) copolymers were synthesized to obtain different structures of graft copolymers with different graft lengths and graft densities. The structure of synthesized EPDM-g-PS copolymers was characterized by

Effects of Exposure to Radiation and Steam on Silicone Rubber Cables Removed From a Nuclear Power Plant

open access: yesHigh Voltage, EarlyView.
ABSTRACT Low‐voltage cables insulated with silicone rubber were harvested from three locations in the primary containment vessel of a boiling water nuclear power plant (NPP). Subsequently, the cable, which was placed in an ambient environment with a relatively higher temperature and the highest rate, was cut into four shorter ones.

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

open access: yesFushe 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.

On the feasibility of watertight face-sealed window-wall interfaces [PDF]

open access: yes, 2019
Watertightness is still a major source of concern in the performance of the building envelope. Even very small deficiencies can cause a significant amount of water leakage which may result in structural degradation or malfunctioning of the insulation ...

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

open access: yesTraditional &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 ...

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

open access: yesPolímeros, 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

open access: yesJournal 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 ...
