DSM Implements Next-generation RTDMA Test Methods for its DeSolite® Supercoatings

Published on 2012-12-11. Author : SpecialChem

As of November 1st, DSM has implemented Real Time Dynamic Mechanical Analysis (RTDMA) into standard Quality Control testing for the mechanical and cure properties for all of its optical fiber primary coatings. Where previous-generation film tensile, elongation, modulus and FTIR cure speed testing methods provided only a range of results based on a few key points, RTDMA provides more precise measurements, delivering accurate cure performance and modulus values using the UV-cure technique. These measurements allow fiber producers to accurately control and more finely tune the draw process.

RTDMA has become a necessary characterization tool with recent advancements in coating technology. In particular, RTDMA is critical for low-modulus and fast-curing primary coatings, such as DSM's latest-generation DeSolite® Supercoatings, which deliver outstanding field performance, microbend sensitivity and signal reliability in even the most demanding applications.

"Although legacy tests have improved over the last 30 years, the engineering limits of these tests have been reached," says Olaf Storaasli, Global Marketing Manager for DSM's Fiber Optic Materials group. "Just as fiber coatings have evolved, so must our method for testing them. The precision that RTDMA delivers allows our customers the stability needed to increase drawing speeds while delivering consistent processing results."
