Journal of Applied Polymer Science: Early View
In this study, a P-N synergistic flame retardant AG601-DOPO (A-D) was synthesized by the reaction of an epoxy resin (AG601) with 9,10-dihydro-9-oxo-10-phosphophenanthrene-10-oxide (DOPO). A-D was then mixed with BA-a in different ratios, heated, melted, poured and cured to obtain samples. These samples were tested and characterized.
To that end, ethylene–propylene–diene monomer (EPDM) rubber, a copolymer of ethylene (45–75%), propylene monomers (13–45%), and nonconjugated dienes (ethylidene norbornene, dicyclopentadiene, and 1,4-hexadiene; 1–11%), was selected for its high hydrophobic characteristics as well as remarkable ozone and light resistivity . These
General Properties of Elastomers
Natural Rubber has a typical service temperature range between –67° F and +180° F. ADVANTAGES: Natural rubber has excellent tensile, elongation, tear resistance, resilience, and electrical insulation. Natural rubber's high resilience is only outperformed by some of the more recent man-made polyisoprenes and polybutadienes. Natural rubber
Depending on the rubber type, the degree of unsaturation in the petroleum oil must be considered so as not to interfere with cure rates and subsequently affect the final vulcanizate properties. Petroleum oils are the large volume plasticizer used in elastomers, finding utility in natural rubber, SBR, EPR, and EPDM and neoprene.
Material Choice Guide to Selecting Rubber Compounds
NATURAL RUBBER (NR) Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis. Natural rubber features low compression set, high tensile strength, resilience, abrasion and tear resistance, good friction characteristics, excellent bonding capabilities to metal substrate, and good vibration dampening characteristics.

EPDM Ethylene Propylene Diene Terpolymer Dow Inc.
Driving for better, more sustainable rubber. Ethylene propylene diene terpolymer, or EPDM for short, is a durable material made to withstand the toughest conditions. It can handle high temperatures and abrasive chemicals. Even though it's a tough material, that doesn't mean it has to be tough to work with.
