Chemical Resistance TIKALFLEX Contact 12

Product catalog summary
Overview: This document presents the chemical resistance of TIKALFLEX Contact 12, measured by Shore A Hardness, after exposure to various chemicals over different time periods.
Initial Hardness: The initial Shore A Hardness of TIKALFLEX Contact 12 before chemical exposure is 42.
Exposure Time Intervals: The material was tested at intervals of 1 hour, 3 hours, 6 hours, 30 hours, and 32 hours.
Chemical Resistance Results:
  • Hydrochloric Acid (10%): Hardness decreased to 33 after 32 hours, with slight recovery after 24 hours.
  • Nitric Acid (10%): Hardness reduced to 30 after 32 hours, with minor recovery after 24 hours.
  • Sulphuric Acid (10%): Significant decrease to 28 after 32 hours, with partial recovery after 24 hours.
  • Phosphoric Acid (10%): Maintained hardness around 36-41 throughout the test.
  • Acetic Acid (10%): Hardness dropped to 26 after 32 hours, with recovery to 31 after 24 hours.
  • Citric Acid (10%): Hardness increased to 44 after 32 hours, showing good resistance.
  • Lactic Acid (10%): Hardness increased to 45 after 32 hours, indicating strong resistance.
  • Hydrogen Peroxide (30%): Hardness decreased to 33 after 32 hours, with some recovery after 24 hours.
  • Ethanol (100%): Hardness increased to 42 after 32 hours, showing good resistance.
  • Xylene (100%): Hardness decreased significantly to 18 after 32 hours, with recovery to 39 after 24 hours.
  • MEK (100%): Hardness increased to 45 after 32 hours, indicating strong resistance.
  • Mineral Spirit (100%): Hardness increased to 45 after 32 hours, showing good resistance.
  • Petrol, Unleaded (100%): Hardness decreased to 23 after 32 hours, with recovery to 38 after 24 hours.
  • Diesel (100%): Hardness decreased to 23 after 32 hours, with minimal recovery.
  • Sodium Hydroxide (10%): Hardness remained relatively stable, around 36-40.
  • Sodium Chloride (10%): Hardness remained stable, around 36-39.
  • Sodium Hypochlorite (12%): Hardness remained stable, around 33-38.
  • Distilled Water (10%): Hardness remained stable, around 35-39.
  • Sugar Solution (Saturated): Hardness remained stable, around 37-40.
  • Vegetable Oil (100%): Hardness decreased slightly to 34 after 32 hours.
Conclusion: TIKALFLEX Contact 12 shows varying degrees of chemical resistance, with strong resistance to citric and lactic acids, ethanol, MEK, and mineral spirits, while showing significant degradation in the presence of xylene and diesel.
