    PROPERTIES
  • 1) SL-2201 is a thermoplastic resin and exhibits good solubility in BR, SBR, CR and NBR rubbers. During the vulcanization of rubber compounds, SL-2201 is function as a softening agent, plasticizer and an adhesion promoter. The cross-linking reaction of SL-2201 with a methylene donor produces rubber compounds with superior reinforcement and hardness properties.
  • 2) In addition to enhanced hardness, SL-2201 resin significantly improves the abrasion resistance, tear resistance, tensile strength and modulus properties of rubber compounds. The elongation of cured rubber is decreased only slightly.
  • 3) SL-2201 can also function as an adhesion promoter. Therefore, this resin used in the manufacture of various reinforced rubber articles.
  • 4) With SL-2201 resin, the Mooney viscosity of rubber compound could be reduced, which in turn could improve the filler dispersions of various rubbers.
  •  

    APPLICATIONS

  • 1) SL-2201 is mainly used in bead area of tires, rubber soles and car window sealing strips.
  • 2) It is suggested that SL-2201 can be used at about 5~15 phr levels. At the same time, 7~10%(wt%) hexamethylenetetramine(HMT) or hexamethoxymethylmelamine (HMMM) as methylene donor should be added.
  • 3) In order to avoid the scorching problem of rubber compounds, SL-2201 resin should be added during the first mixing stage. The methylene donor should be added with an accelerator and sulfur at the final mixing stage.
