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 choice for protective gear and cushioning materials (Fig. 1). 2. High-Compression Epoxy Foam: Maintains rigidity and support under high-pressure conditions, perfectly balancing hardness and toughness. These materials can be customized according to your application, eliminating the need to compromise between lightweight and strength (Fig. 2). 3. Baked Foam Core: By precisely controlling heat to activate the foaming agent, it forms a fine and uniform cell structure, serving as the key core for sandwich composite structures. When combined with carbon fiber composites, this foam core can reduce structural weight by 40–60%, achieving extreme lightweight performance. It is commonly used in high-end sports equipment and high-performance structural components (Figs. 3, 4). We welcome you to contact us if you are interested.            —Author: Ms. Huifang Lai

Activity § Spay and Neuter Program for Stray Dogs and Cats

Since 2023, we have been sponsoring the Yunlin Let Love Flow Animal Care Association, supporting its annual spay and neuter program for approximately 150 stray dogs and cats. To date, more than 300 animals have successfully undergone sterilization through this initiative. We support this program because we believe that prevention is better than a cure. Spaying and neutering are effective ways to control the stray animal population at its source, reduce the birth of unwanted animals, and improve public hygiene while minimizing human–animal conflicts. Ultimately, this helps create a more harmonious coexistence between residents and companion animals. In addition to sponsoring the program, we have also adopted two former stray dogs, providing them with a safe and caring home within our facility.

Knowledge § What Is the Principle of Recyclable Epoxy Resins? (2)

For example, by introducing functional groups such as ester, carbonate, or carbamate into the resin, these groups remain in the network structure after the resin reacts with a curing agent. When this cured resin is immersed in chemicals like polyamines, the polyamines react with the functional groups, converting them into small molecules terminated with amine groups. This reaction breaks the original network structure, producing a material that can flow or dissolve in a solvent. The products obtained from this recycling process—the small molecules with terminal amine groups—can then be mixed with fresh resin. They undergo a new curing reaction to form a new crosslinked network, giving the discarded material a second life.

Living § My Milestone

For many, this trek is not particularly difficult, but for me—once over 130 kg and prone to swollen feet after long periods of walking—it was a significant milestone. Let me tell the story from the beginning…When I first joined Everwide in 2022, I once stood in the lab for over eight hours to meet an urgent shipment, without even having time to drink water. The next day, my feet were so swollen that I could barely walk. That moment made me realize that the body is not a machine; it cannot endure endless overexertion. To go further in life, I needed to prioritize my health and start making changes. At the 2024 year-end meeting, senior colleague Qingmei shared the book Atomic Habits. One line struck me deeply: “Don’t set a distant, unattainable goal—start by building a frequency you can sustain.” Over the past year, I tried to follow this principle, even if it meant spending just five minutes in the gym. Gradually, my weight dropped from 130 kg to 90 kg, and the knee braces that had once been my constant companion stayed in the drawer for months. During the Jiaming Lake trek—from Xiangyang Mountain Hut to the summit—there were several moments I wanted to give up. But I reminded myself: “As long as I reach the lakeshore, I will witness the results of the effort accumulated every day.” Change is not achieved through a single burst of effort—it comes from persistence. This is a principle I have also learned at Everwide: whether in material research and development or in physical training, we don’t compete in speed, but in perseverance. I look forward to moving forward with everyone in even better health.                                           —Author: Mr. Wenhao Cai
