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 ...

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 ...

EPDM/CIIR Blends: Effect of EPDM Grade on Mechanical Properties

International Journal of Polymeric Materials, 2007
Blends of chlorobutyl rubber (CIIR) with two grades of ethylene-propylene diene monomer rubber (EPDM) were prepared and the effect of blend ratio on the cure characteristics, hot air ageing resistance, steam ageing resistance, and mechanical properties were evaluated.

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.

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 ...

Polypivalolactone grafts on EPDM

Journal of Polymer Science: Polymer Chemistry Edition, 1978
AbstractRandom copolymers of ethylene, propylene, and 1,4‐hexadiene (EPDM) were carboxylated by reaction with thioglycolic acid or with maleic anhydride. Treatment of these polymers in tetrahydrofuran solution with tetrabutylammonium hydroxide generated carboxylate anions, which initiated the graft polymerization of pivalolactone.

EPDM/modified halloysite nanocomposites

Applied Clay Science, 2010
Abstract Halloysite nanotubes (HNTs) were modified by γ-methacryloxypropyl trimethoxysilane (MPS) to improve their dispersion in ethylene propylene diene monomer (EPDM). The EPDM/HNT nanocomposites were prepared by mixing 0, 5, 10 and 30 parts per hundred rubber (phr) of HNTs with EPDM on a two-roll mill.

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.

Aging of EPDM rubber

Journal of Applied Polymer Science, 1987
AbstractThe effect of oxidative and thermal aging of EPDM raw rubber and rubber vulcanizate on gelation, network structure, and techical properties has been studied over a wide range of temperatures and times of aging. Three grades of EPDM having different types of diene have been considered.
