Photostabilization of EPDM Sulfur Vulcanizate with White Filler.

synthesis of aluminum triacrylate as reactive filler in epdm reinforcement

the organo-metal salt of aluminum triacrylate (alta) with a general formula of (ch2=chcoo)3al was  synthesized  as  a  reactive  fller  for  elastomers through a two-step synthetic procedure. fourier transform-infrared spectroscopy (ftir), dsc and dta were employed for alta analysis and to study its cure characteristics. in this research, two composites based on ethylene propylene diene monomer...

Photostabilization of Polymers

The photodegradation of polymers has been studied from the early years due to its commercial production. Most plastics are affected by exposure to sunlight in conjunction with other natural weathering forces such as oxygen, water, and heat. Almost all synthetic polymers require stabilization against adverse environmental effects. The consequences of photodegradation depend on the nature of the ...

EPDM/modified halloysite nanocomposites

Photostabilization of papaverine hydrochloride solutions.

Abstract: The stability of aqueous and non-aqueous papaverine hydrochloride solutions exposed to the UV radiation is poor. In order to enhance its photo-stability suitable light absorbers may be used. There werefour photo-protectors considered in this work: 4-aminobenzoic acid, sodium benzoate, methyl 4-hydroxybenzoate and propyl 4-hydroxybenzoate, whose UV absorption spectra characteristics ma...

Mechanical, Thermal, Electrical and Morphology Characterization of Ethylene Propylene Diene Monomer - Nanoclay Composites

The effect of nanoclay in combination with other inter fillers in ethylene propylene diene monomer (EPDM) rubber vulcanizate were studied. Curing characteristics were carried out using rubber process analyzer (RPA). Mechanical, thermal and morphology characterization of EPDM nanoclay composites were studied.
