Trident™ Application Highlight: Thermal Conductivity and Effusivity of Latex and Non-Latex Condoms
This document highlights the measurement of thermal conductivity and thermal effusivity of latex and non-latex condoms using the Transient Plane Source (TPS) Thin Films Utility and the Modified Transient Plane Source (MTPS) method
Thermal conductivity and thermal effusivity are relevant material properties in condom development and quality assessment. Thermal conductivity governs the rate at which bodyheat passes through the material, thereby influencing the rate of heat dissipation. Thermal effusivity characterizes how readily a material exchanges heat with its surroundings at initial contact, thereby determining the material's immediate warm or cool feel.

Thermal conductivity was measured using the Trident Thermal Conductivity Instrument equipped with the Transient Plane Source (TPS) sensor and the Thin Films Utility, using a 13 mm sensor. Thermal effusivity was measured using the Modified Transient Plane Source (MTPS) sensor, which is available exclusively on the Trident. Trojan BareSkin latex and a non-latex alternative were tested. All measurements were performed at room temperature.To read more, download the PDF below.
