Physical tests

Cure Characteristics of Rubber

Dry rubber content (DRC) and Total solid content of the latex:


  • We test DRC and total solid content of the latex according to ASTM standard D 1076 and ISO procedure.
  • We have highly precise weighing balance with accuracy of 0.01 mg for doing these analyses.

Stability of the latex:


  • We test according to ASTM standard D 1076 and ISO procedure.
  • We analyze mechanical stability, chemical stability, heat stability, Emulsion stability of latex sample.
  • We have klaxon latex mechanical stability test apparatus to analyze stability.
  • Test is done at 14,000 RPM.
Cure Characteristics of Rubber

Viscosity


  • We test according to ASTM standard D 1076.
  • We have Brookfield LVT model, which gives an accurate viscosity result .
  • We will able to measure the viscosity ranging from 50-140,000 centipoises.

Cure Characteristics of Rubber

Volatile fatty acid:


  • We test according to ASTM standard D 1076 and ISO procedure.
  • Volatile fatty acid is determined by Markham still apparatus with steam generator.

We too do following tests on latex according to ASTM and ISO Procedure:


  • Density
  • Sludge content
  • Coagulum content
  • pH of latex
  • Conductivity of latex
  • Alkalinity of Latex
  • KOH number of latex
  • ZNO number
  • Nitrogen content
  • Chloroform number
  • Non volatile acid number
  • Carbon dioxide number
