Experiment  § Epoxy Resin for Handicrafts In handicraft production, immersion and casting techniques can be used to create works that combine practicality with aesthetic value, such as keychains, coasters, and bookmarks (Figures 1 and 2). These differ from the craft style presented in Issue 338. In this application, a low-viscosity epoxy resin, JD052-3, was selected. When mixed with pigments, the viscosity remains below 1000 cps, providing excellent leveling properties and a

Experiment  § Low-Density Foam We offer a variety of foaming processing solutions tailored to different application needs. Whether you require room-temperature foaming for rapid forming to save energy and time, or precision baking techniques for optimal performance, we can precisely control the bubble structure to ensure uniform density and stable material integrity. 1. High-Flexibility Polyurethane (PU): Offers excellent shock absorption and rebound, making it the ideal choi

The Meaningful Days in Everwide In 2025, industries around the world are moving toward smarter operations and focus on sustainability. Everwide Chemical is keeping pace with these developments. Over the past year, we have carried out several internal improvements and digital transformation initiatives. We have also obtained ISO 50001 Energy Management System certification, demonstrating our commitment to energy saving and carbon reduction. As in previous years, we participate

Experiment  § EMI Shielding and Sealing Silicone Electromagnetic interference (EMI) control utilizes conductive or high-permeability materials to reflect or absorb unwanted electromagnetic waves, ensuring the stable operation of electronic components within a specific area or device. During design and assembly, three requirements must be considered simultaneously: EMI protection, structural fixation, and environmental sealing. To meet these requirements, Everwide has develope

Experiment  § AT-710 Automatic Potentiometric Titrator Red adhesive (chip red adhesive) is a material used in electronic assembly processes to secure components, ensuring they remain safe through subsequent high-temperature and vibration processes. In the Surface Mount Technology (SMT) process, small components such as resistors and capacitors often have a small dollop of red adhesive underneath (Figures 1 and 2). Its function is to form a central “adhesive bump” under the co

Experiment  § Medium- and Low-Voltage Cold-Shrink Silicone Cable Insulation Components We have developed FX301-14, an electrical-grade liquid silicone rubber (LSR) for insulation applications. This product is a two-component, dark gray, paste-like, tear-resistant LSR, specifically designed for injection molding (Fig 1,2). It offers excellent resistance to yellowing, outstanding elastic recovery, superior thermal aging resistance, and ease of processing. In power system applic

Experiment  § Development of Furan Prepreg Resin Furan resins can be produced from furfuryl alcohol (FA), which is extracted from agricultural waste such as corn cobs, making them an important material in the field of sustainable and green chemistry (Figure 1–2). After polycondensation, furan resins form a cross-linked network structure. Due to the inherent stability of the furan ring, these resins exhibit excellent resistance to acids, alkalis, solvents, and heat, and are co

Experiment  § AT-710 Automatic Potentiometric Titrator Everwide has introduced an AT-710 automatic potentiometric titrator to enhance laboratory analysis efficiency and accuracy. This instrument is applied to the determination of Total Acid Number (TAN), Total Base Number (TBN), Epoxy Equivalent Weight (EEW), Hydroxyl Value (OH Value), and isocyanate group (–NCO) content (Figure 1). The AT-710 utilizes potentiometric titration for analysis. By monitoring changes in ion concen

Experiment  § Sensitizers I Have Studied With the rapid development of polymer materials in industrial and medical fields, advances in polymerization techniques have become a key driver of material innovation. Among these, ionic polymerization is characterized by high efficiency and controllability, and it is increasingly applied in the preparation of high-performance resins and precision materials. In typical ionic polymerization reactions, the wavelength range of light abso

Experiment  § Fast-Drying Screen Printing Adhesive Screen printing is a long-established and widely applied printing technique. Its core principle lies in using a mesh screen as a stencil, allowing ink to pass through the mesh and transfer onto the surface of the substrate. This technique is commonly used in textile. printing, packaging printing, as well as the printing of instrument panels and printed circuit boards. The screen itself is a critical component in the printing
