GR latex, and dipped films produced from compounded GR latex, contain none of the Hevea allergens known to elicit Type 1 systemic allergic reaction. The polymer phase of GR latex has a lower bulk viscosity and a higher resin content than that of NR. In addition, GR latex serum and rubber lack the activating components present in NR latex. As a result, GR latex cures more slowly and reaches a lower state of cure. The aged stress-strain properties of cured GR films are nontheless similar to those of NR films ER -
