Hypalon^® chlorosulfonated polyethylene from DuPont Performance Elastomers

  Hypalon^® chlorosulfonated polyethylene

  Hypalon^® Applications

Heat and oil resistant rubbers. Outstanding weatherability in bright colors. Oil resistance improves with higher chlorine content; low temperature properties, with lower chlorine content types. Hypalon^® 40 is a general purpose polymer.

          Hypalon^® 20
For flexible substrates and good low-temperature flexibility.

          Hypalon^® 30
For rigid substrates hard, glossy films and good oil resistance.

          Hypalon^® 40
Basic general purpose type with good oil resistance and good heat resistance.

          Hypalon^® 40S
(Soft) for lightly higher durometer vulcanizates.

          Hypalon^® 45
Excellent uncured properties with flexibility, higher hardness and better tear strength.

          Hypalon^® 48
Hard, glossy films. Somewhat better low-temperature properties than Hypalon^® 30.

          Hypalon^® 4085
For highly extended compounds, lower durometer vulcanizates.

          Hypalon^® HPG-6525
For highly extended compounds—lower cost vulcanizates. Better heat and temperature performance.

Adhesion Promoter

          Hypalon^® CP-826
Hypalon^® CP-826 has been specifically developed for adhesion to polypropylene and blends thereof. It can be used in dilute solutions as a wash primer or tie layer between materials that are difficult to adhere. It can also be used as an adhesion modifier for coatings, adhesives and inks. CP-826 has shown to be a good primer for polyurethane foam used in athletic shoe construction when over coated with solvent base polyurethane adhesive. Has good stability in aromatic hydrocarbons.
