Bio-Based EPDM Rubber and Sustainable EPDM Compounding

2017
ARLANXEO Performance Elastomers has made a pioneering move toward exploring a future based on renewable resources, by developing the world's first bio-based EPDM rubber commercialized under the tradename Keltan Eco. Regular EPDM products, including ARLANXEO Performance Elastomers' Keltan EPDM products, are produced from fossil raw materials, that is ...

Crosslinking with S2C12 of EPDM rubbers and of EPDM grafted with polyacrylic acid

European Polymer Journal, 1974
Abstract EPDM rubber swollen in n-butylacetate was crosslinked with S2Cl2 solution in n-butylacetate. From swelling measurements in benzene and the Flory-Rehner equation, the density of elastically-active network chains was calculated as a function of time.

Solution autoxidation of EPDM and termonomers

European Polymer Journal, 1971
Abstract Oxygen uptake of 3 low molecular weight ethylene-propylene terpolymers (EPDM) and their respective bicyclic diolefin termonomers (dicyclopentadiene, ethylidene norbornene, and methyl endomethylene hexahydronaphthalene) has been measured at ⩽70°.

Ageing of EPDM—I: Photo and thermal stability of EPDM hydroperoxides

Polymer Degradation and Stability, 1996
Abstract EPDM hydroperoxides photogenerated by singlet oxygen were decomposed both by UV (λ ≥ 300 nm) and thermal (85 °C) irradiation under vacuum. The peroxy radical formation was followed by performing photolysis at −60 °C directly in the cavity of an ESR spectrometer.

Crystallinity in EPDM terpolymers

British Polymer Journal, 1979
AbstractThe crystallinity of a series of ‘medium‐high’ green strength EPDM terpolymers has been examined by X‐ray diffraction and thermal analysis. It has been found that the crystallinity of such materials can vary from 0.20% as measured by thermal analysis, and depends on the E:P ratio in the polymer.

ADVANCEMENTS IN EPDM SPONGE COMPOUND PROCESSING USING EPDM BIMODAL POLYMERS

Rubber Chemistry and Technology, 2011
Abstract Ethylene-propylene-diene (EPDM) elastomers are the primary polymer choice for automotive weatherseal applications due to their outstanding weathering and heat resistance properties. Automotive sealing systems are complex in design; in particular, door seals are one of the most complex components of the sealing system, generally ...

Rheological properties and compatibility of NR/EPDM and NR/brominated EPDM blends

Journal of Applied Polymer Science, 2003
AbstractEthylene–propylene–diene terpolymer (EPDM) was modified by bromination reaction. Blending the resulting brominated EPDM with natural rubber (STR5L) and blending the unmodified EPDM with STR5L at various compositions were carried out. The rheological properties of the blends were investigated using a capillary extrusion. Shear flow curves of the

TREATISE ON EPDM

Rubber Chemistry and Technology, 2012
ABSTRACT EPDM is the designation given for a saturated polymer chain of the polymethylene type, consisting of ethylene, propylene, and diene. It has been and continues to be one of the most widely used and rapidly growing synthetic rubbers. Technology development has been driven by novel catalysts and processes that have expanded the range of ...

The Compatibilization of EPDM/SBR Blends by EPDM-Graft-Styrene Copolymer

Polymer-Plastics Technology and Engineering, 2005
Ethylene propylene diene rubber (EPDM) and styrene butadiene rubber (SBR) blends were compatibilized by a graft copolymer EPDM-graft-styrene. This compatibilizer was prepared by gamma radiation induced grafting of EPDM with styrene monomer. The compatibilized blends were evaluated by scanning electron microscope and dielectric properties.

Spotlight on EPDM Elastomers

Polymer-Plastics Technology and Engineering, 1992
Abstract Etylene-propylene diene monomer (EPDM) rubbers have become widely recognized as an important class of elastomers in an enormous variety of consumer-type products. Typical examples where this material is used include seals around automotive doors, trunks, and windows; hosing materials used in automotive radiator applications, ply-roofing ...
