ELANTAS EN-16

Main features

  • Cartridge-Friendly Four-to-One Mixing
  • Defined 30-Minute Working Window
  • High-Elongation Cured Potting

Product Description

CONATHANE EN-16 Two-Component Polyurethane Potting Compound is an unfilled, 100% solids polyether-based polyurethane system for harness breakouts, watertight connectors, cables, and cable-end seals. The 4:1 mix ratio by weight and volume produces a 4,000 cP mixed material with a 30-minute work life at 25 deg C. Cure may be completed in 7 days at 25 deg C or 16 hours at 80 deg C. The cured elastomer reaches Shore A 80, 510% ultimate elongation, and 4,200 psi tensile strength, supporting flexible, abrasion-resistant potting and molded electrical applications.

Key features

  • Cartridge-Friendly 4:1 Mixing: The four-to-one volumetric ratio supports controlled cartridge or meter-mix processing.
  • 30-Minute Work Life: The mixed compound provides a defined processing window at 25 deg C.
  • High Cured Elongation: Typical 510% ultimate elongation provides a flexible final elastomer profile.

Applications / Suitable for

  • Harness breakouts
  • Watertight electrical connectors
  • Cables and cable-end seals
  • Abrasion-resistant mechanical castings

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.

Surface Resistivity
1.7 x 10^14 Ohms/sq
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
