  This product is a rubber antioxidant, selected from a variety of paraffin wax, microcrystalline wax, etc. compound mixture.  In  the  rubber  mixing  and  curing  process  the  product  was  completely  dissolved.  In  the  rubber  products during  use  and  storage to  form  a  supersaturated  solution  of  paraffin  wax  system,  makes  continuous  paraffin hydrocarbon molecules migrate to the rubber surface. This migration until therubber surface of the paraffin and the internal concentration to achieve a balance so far. Solubility and migration of this dynamic balance between the two,
so that the goods in the rubber surface of the long-term stability of the wax forms a film, thereby preventing oxygen and ozone attack and destruction of the rubber, and wax film also weaken the role of light damage to rubber .This product is a reasonable regulation and control through technological means n-alkanes and the composition ratio of
isoparaffin, reasonable control of carbon number distribution, so that the product has a high melting point, stability, viscosity  range,  etc.,  in  the  migration  of  high-temperature  environment,  good  performance,  better  play  excellent protection performance.

Application Fields

  Tires,  conveyor  belts,  etc.,  all  kinds  of  rubber  products  for  high  temperature  applications.  It  can  be  used  with Low-temperature  protective  wax  and  chemical  antioxidant  to  protect  shared,  thereby  expanding  the  scope  of protection and improve the protective effect.


  1. Granular product suitable for use with automatic and manual measurement, in order to ensure dispersion, it is recommended to join in the initial mixing.
  2. This product is recommended to use the mixer in the mixing, mill application recommended mixing temperature should be higher than its melting point is above 10 ℃
  3. Tire formula recommended dosage 1-4phr; transport with 2-6phr; other rubber products based on experimental results to determine, the recommended maximum dosage is 10phr.

  1. Temperature, environment and climate protection, It has a better protective effect than normal paraffin in rubber.
  2. It sustained the formation of uniform protective wax film to prevent the rubber to heat, ozone, light and other
damaging effects.
  3. It has a wide carbon number distribution of a reasonable, good compatibility with rubber。
  4. It has rational n-alkanes with the isoparaffin content, stable and reasonable rate of migration of paraffin wax. It
has a good protective effect in rubber.
  5. White or yellow granules, no coloring, no polluted products, good dispersion.
  6. The product formed a solid and resilient protective film. Deformation of rubber protective film will not break or
crack occurs.


  20kg, complex paper bag, 1 ton/pellet.

Safety and transport

  FNL-67T is not classified as a dangerous good according to transport legislation, so we should transport it in term of undangerous good. It has not any hurt if you use it in right way.


  FNL -67T should be stored in cool and dry place, with temperature lower than 35oC. If these rules are obeyed, the product can be stored at least two years. If stored at higher temperature caking may occur, this, however, has no effect on the performance. The production date is stated on the lot number on the labels of each sack.
