Resulting Properties

Liquid natural rubber can be used in hot melt sealants as a plasticizer/oil substitute to afford sealants which are easily applied at moderately elevated temperatures. The addition of these polymers often augments the sealant's adhesive qualities. The above adhesive formulation shows the improvement in peel strength achieved by adding natural rubber to a SBS filled hot melt cable sealant formulation. The source of SBS / Natural Rubber Hot Melt Cable Sealant (B) is DPR Industries.
