[Book] Measures Against Degradation and Discoloration of Polymer Materials (No. 2104BOD)

Technical Specialized Books - Mechanisms of Degradation, Optimal Formulation of Additives, Product Troubles and Countermeasures, Analysis and Evaluation.

■ Points of this Book Understanding the mechanisms of degradation and discoloration of polymer materials - How do auto-oxidative degradation and discoloration progress under the influence of light, heat, and metal ions? - What factors promote hydrolysis? - How can we prevent cracking caused by solvents, oils, surfactants, and other chemicals? - The degradation mechanisms and stabilization of various materials such as thermosetting resins, thermoplastics, and composite materials. Optimal formulation of additives - Formulations considering antagonistic effects, compatibility, and migration. - Responses when antioxidants themselves discolor. - Synergistic effects and antagonistic actions of UVA/HALS. - Prevention of poor dispersion and blooming caused by metal inactivators. - Selection of antibacterial and antifungal agents according to purpose. - Selection of curing agents considering cost, safety, and lifespan. - Mechanisms of bleed-out occurrence and countermeasures. Troubles and countermeasures for polymer products - Degradation and prevention of protective coatings on automobiles due to temperature, pollen, bird droppings, stones, etc. - Scratch resistance, chemical resistance, and hardness in automotive decorative films. - How to meet the safety, reliability, and strength required in the railway sector? - Troubles such as burning and odor in packaging materials and their countermeasures. - Durability, seismic resistance, fire resistance... what are the required properties in the construction field?

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.

In recent years, as the importance of data integrity (DI) compliance in GMP environments has increased, there has been a growing call to deepen understanding of 21 CFR Part 11. This content introduces an on-demand presentation that organizes the background of Part 11, its relationship with DI, and its positioning in CSA guidance, while explaining the basic concepts of electronic records and electronic signatures. ■Content - Background and basic concepts of Part 11 - Relationship with data integrity (DI) - Positioning in CSA guidance - Basic requirements for electronic records/electronic signatures *This content is based on information as of March 17, 2026. *The information provided is intended for general informational purposes and does not guarantee specific compliance or suitability.
