  • 1) SL-1405 is a novolac type alkyl-phenol ¨C formaldehyde resin and can provide long-term effective tackiness, plasticity and softening properties to rubber compounds
  • 2) SL-1405 resin exhibits good scorch protection to rubber compounds and has no impact on compound¡¯s curing properties. It helps to maintain good physical and mechanical properties of rubber vulcanizates.
  • 3) Because of its low softening point, SL-1405 exhibits positive effects on rubber compounding and rubber-plastic blending processes and provides good physical properties to these compounds.
  • 4) SL-1405 resin can be extensively applied to natural and synthetic rubbers, like SBR, BR, EPDM, and their blends to produce high-performance tires, convey belts, hoses, rollers, rubber plates, rubber inner liners, retread materials, wires and cables. This resin can also be used as tackifying agent in adhesives. This resin also can be used in rubber-plastic products.

  • 1£© SL-1405 resin is preferably be added during the first stage of mixing to facilitate the uniform dispersion of this product into rubber compounds.
  • 2£© It is recommended to use SL-1405 resin at 2-5 phr loading. The rubber processing oil level in the compounds can also be reduced properly.


  • SL-1405 25kg( net weight), Kraft bag inner PE coated.


  • This material can be stable for 18 months under the normal storage conditions. However, precautions must be taken to avoid exposure to sunlight and always, store this material in a sealed container under the dry and cool conditions.
  • Refer to Material Safety Data Sheets (MSDS) prior to using this resin.
