Product Information

yWhat is DAIREC?z
 gDAIRECh is the name of the reclaimed rubber product that is manufactured by Daiei Rubber Co, Ltd. At present, the question of recycling is a major social issue. Our company has from the very onset been aware of the limited resources available and for the last 40 years has been producing gDAIRECh, a recycled product that is a sign of our history and results.

  gDAIRECh is recycled unvulcanized rubber that has been produced by treating vulcanized rubber chemically and physically to remove its resilience and restore its adhesiveness and plasticity. It can undergo the same processes and sulfurization as new rubber which allows it to be used in the manufacture of rubber products.

  In comparison to new rubber, DAIRECfs has a superior adhesiveness, plasticity, Workability consistence, strength and aging resistance.

  In the Rubber Industry, DAIREC is not used by itself but is blended with other products and processed to give it an improved efficiency. It is used as the main ingredient to make glue for tapes, sealants and in this way it exhibits its adhesiveness and plasticity features. 

 In this way, DAIREC is widely used in File Wrapping material, Civil Engineering material and other Industrial Material.
