May 22 (Fri) AndTech to Hold WEB Online Zoom Seminar: 'Fundamentals and Practice of Property Control by Polymer Stretching, Orientation, and Crystallization - Process Optimization to Enhance Strength and Optical Properties of Films and Fibers'

AndTech Inc. (Headquarters: Kawasaki City, Kanagawa Prefecture, President: Masao Toyama, hereinafter referred to as AndTech) will hold a lecture on polymer stretching as part of its R&D support Zoom courses, titled 'Fundamentals and Practice of Property Control by Polymer Stretching, Orientation, and Crystallization - Process Optimization to Enhance Strength and Optical Properties of Films and Fibers,' featuring leading experts. Polymers that constitute films and fibers, through molecular orientation and crystallization by stretching, acquire unique structures and properties, exhibiting strength against tension and flexibility against compression. This lecture will explain the basics of stretching, orientation, and crystallization, and how properties such as birefringence, strength, Young's modulus, and thermal shrinkage are controlled by stretching conditions, incorporating the latest research. This course is scheduled to open on Friday, May 22, 2026.

This seminar will explain the relationship between the structure formed and the properties, based on the fundamentals of stretching, orientation, and crystallization in fibers and films, incorporating the latest research findings. While the properties covered will include birefringence as optical properties, and strength, Young's modulus, and thermal shrinkage as mechanical properties, the concept of controlling structure and properties by stretching conditions is considered applicable to controlling other properties as well. 【Program】 Ⅰ. Polymer Stretching Process 　1. Stretching Equipment 　2. Forces and Heat Applied in the Stretching Process 　3. Stretching Conditions, Structure, and Properties 　4. Stretching Modes 　5. Structures Formed by Stretching Ⅱ. Structure Control by Stretching 　1. Three Elements of Molecular Orientation 　　1.1 Orientation Mode 　　1.2 Degree of Orientation 　　1.3 Orientation Element 　2. Molecular Orientation by Stretching 　3. Oriented Crystallization Ⅲ. Property Control by Stretching 　1. Refractive Index and Birefringence Control 　　1.1 Optical Phenomena and Refractive Index 　　1.2 Refractive Index Ellipsoid and Optical Anisotropy 　　1.3 Origins of Birefringence 　　　(1) Induced Birefringence 　　　(2) Orientation Birefringence 　　　(3) Form Birefringence 　　1.4 Lorentz-Lorenz Equation and Intrinsic Birefringence 　2. Mechanical Property Control 　　2.1 Ultimate Structure and Mechanical Properties 　　2.2 Structure of Stretched Materials and Mechanical Properties 　　　(1) Molecular Orientation and Young's Modulus 　　　(2) Stretching Conditions and Thermal Shrinkage 　　　(3) Strength and Elongation 【Main PR Points of the Lecture】 Films and fibers exhibit unique properties, being strong under tension and flexible under compression. These seemingly contradictory properties are brought about by the structure formed through stretching. This lecture will teach the principles behind this and the basics of property control by stretching conditions. * Product and service names described in this news release are trademarks or registered trademarks of their respective companies. * The content described in this news release is as of the date of announcement.
