Excellent aging resistance. Improves heat and reversion resistance. Excellent modulus developer and improves tack (no sulfur bloom). Nonstaining and nondiscoloring to rubber compounds and materials in contact with them. Tire cap and base treads, wire breaker, hard apex, rim flange and mechanical goods. Naugex® SD-1 is a sulfur donot used as a partial or complete replacement of sulfur for resistance to heat aging in NR, SBR, BR, NBR (e.g. Paracril®) and EPDM (e.g. Royalene®). Nonstaining and nondiscoloring 4,4’-dithiodimorpholine. Used as a vulcanizing agent and as sulfur donor for partial or total replacement of sulfur in NR, SBR, BR, NBR and EPDM. Provides very good aging resistance and modulus development. Improves heat and reversion resistance, and tack.
