DuPont Mobility and Materials Hypalon® 48 Chlorosulfonated Polyethylene Rubber, Carbon Black Filled Compound  (discontinued **)
Categories: Polymer; Thermoset; Filled/Reinforced Thermoset; Rubber or Thermoset Elastomer (TSE); Chlorosulfonated Polyethylene Rubber

Material Notes: Carbon black compound with 100 parts Hypalon; 27.8 parts sublimed litharge dispersion; 55 parts carbon black; 55 parts aromatic process oil; 0.5 parts MTBS; and 2 parts Tetrone® A rubber accelerator (from DuPont Dow Elastomers). Physical property data below (except mooney viscosity) are for vulcanizate cured 30 min. at 153°C. MatWeb has other entries for different compounds of this Hypalon grade.

General Hypalon® Information: Vulcanizates of this chlorosulfonated polyethylene synthetic rubber are highly resistant to ozone, oxygen, weather, heat, oil, and chemicals. Hypalon resists discoloration on exposure to light and is widely used in light-colored vulcanizates. It can be compounded to give excellent mechanical properties. Several grades are available, all of which may be processed and used in the usual manner for solid elastomeric vulcanizates. Various grades of Hypalon have been used in single-ply roofing systems; auto power steering and oil cooler hoses; chemical-resistant liners; cable sheathing; and other coatings.
