DYPHENE? 8318 Formaldehyde, polymer with 4-(1,1,3,3-tetramethylbutyl) phenol CAS# 26678-93-3
Dyphene? 8318 is an oil-soluble, non-heat reactive alkyl phenolic novolak resin that imparts exceptional initial tack and tack retention to rubber compounds.? It is used extensively as a tackifier in tire compounds based on blends of NR, SBR and BR.
- Imparts high initial tack in green rubber stock (auto-adhesion)
- Retains a high level of tack even after extended exposure to high temperature and humidity.
- Exhibits good compatibility.
- Offers greater economy than many less expensive resins because lower loadings of DYPHENE? 8318 can yield equivalent tack.
- Functions as a processing aid, dispersion aid for other compounding ingredients, and reduces compound viscosity.
- Out performs hydrocarbon resins for tack, tack retention and physical properties in many applications.
SUGGESTED USES:? Tackifying resin for building tack in tire carcass stocks using NR/SBR and NR/SBR/BR blends, and inner liner recipes containing chlorobutyl/SBR/NR blends.? Tackifying resin for tire cements, rubber-compounding applications that now use hydrocarbon resins.
