Polychloroprene (CR)

Elastomers with good heat and fuel resistance which make them suitable for use in automotive belts, hoses and wire and cable applications. In addition, Polychloroprene’s ability to crystallize contributes to fast bond strength development making it ideal for adhesive applications.
