Characteristics
Nipol 2518FS VP 40.5 11.0 30 50 80 -44 Fiber and rubber adhesion for RFL. Excellent adhesiveness with nylon cords.
Nipol 2518GLA VP 40.5 11.0 25 45 200 -44 Fiber and rubber adhesion for RFL. Excellent adhesiveness with nylon cords and excellent initial adhesiveness with polyester cords. Good adhesiveness with aramid cords.
Nipol LX110 SBR 40.5 11.5 55 60 80 -47 RFL type with high adhesive strength. Soluble with VP latex. These are frequently used together.
Nipol LX112 SBR 40.5 11.0 30 60 80 -47 Same as the above. Slightly lower viscosity than LX110. Used with VP latex.
  • Notes
    1. VP: styrene-butadiene vinylpyridine copolymer
    2. SBR: low styrene-butadiene copolymer
