In addition to having a presence on the exhibit floor, T & T Marketing will also be taking part in a technical presentation at IWCS.
At this year’s conference, T & T’s Technical Director, Paul Lorigan, will be presenting a paper entitled “Quantification of the Flexibility of Flame Retardant Insulation and Jacket Materials When Designing Wire & Cable Products.” The presentation will take place at 2:40 p.m. on Thursday, October 8th. It will be one of the presentations that make up Session 18: Flame Retardant Technology.
In his presentation, Paul Lorigan will discuss the selection of wire and cable insulation and jacket materials for flexible constructions. Design engineers typically seek softer materials. The softness or hardness is most often quantified by Durometer Testing in the Shore A scale. Although there is good correlation between hardness and flexibility with unfilled non-flame retardant materials, there is less correlation as flame retardant fillers are added to flexible polymers. Certain jacket materials can be indistinguishable in hardness but drastically different in their actual flexibility. Lorigan’s paper reviews the ASTM procedure for hardness testing and proposes the use of various flexural moduli as a better method to quantify flexibility.
