To further enhance product quality and reduce defects, we leverage the off-hours of night-shift employees to conduct training on key quality issues. The training focuses on common problem areas, with participants collaboratively analyzing root causes and developing preventive measures for the future. We are confident that this series of initiatives will effectively mitigate quality issues, lower defect rates, and reduce scrap and rework costs, thereby delivering positive results.

Combined Salt Spray Test Chamber: A More Realistic Cyclic Corrosion Testing Solution
Mar 31,2026
This month, the company acquired a new piece of equipment—the combined salt spray chamber—providing another significant boost to our testing capabilities.
Cyclic corrosion testing is a more realistic salt spray test than traditional steady-state exposure. This is because real-world outdoor exposure typically involves alternating dry and wet conditions; only by simulating these natural, cyclical environmental factors does laboratory accelerated testing become meaningful. Studies have shown that, following cyclic corrosion testing, the relative corrosion rate, microstructure, and morphological features of test specimens closely resemble their outdoor corrosion behavior. Therefore, cyclic corrosion testing provides a more accurate simulation of real-world outdoor exposure than conventional salt spray spraying.

Dear Valued Customers:
Recently, the international situation in the Middle East has experienced some fluctuations. Some customers have expressed concerns that this could affect the supply of raw materials, potentially leading to material shortages or production disruptions. In response, our company attaches great importance to this issue and would like to provide the following clarification:
After a comprehensive review, we can confirm that all raw materials used in our production are sourced from suppliers outside the Middle East. Our supply chain is well-established and diversified, with multiple reliable and controllable sources for key raw materials. Currently, our inventory levels are sufficient, and our production operations are running smoothly—neither the Middle East situation nor any other external factors have impacted our supply chain. There is no risk of material shortages or production line shutdowns at this time.
Our company remains firmly committed to putting our customers first and continuously optimizing our supply chain management system to ensure a stable supply of products. We will continue to closely monitor developments in the international situation, promptly address any potential risks, and do our utmost to meet our customers’ production needs.
Thank you for your long-term trust and support!
Celebrate the Lantern Festival together.

Natural rubber (NR) is an elastic solid produced by processing a milky sap collected from specific plants. Its main component is polyisoprene, a polymer structure that endows it with unparalleled high elasticity, flexibility, and resistance to fatigue.
Properties of Natural Rubber and Its Main Production Areas
Mar 02,2026
I. Advantages of Natural Rubber:
1. High Elasticity: It features a high rebound rate, low hysteresis loss, and low heat generation.
2. High Strength: The tensile strength of pure rubber vulcanizates can reach 17–25 MPa; after reinforcement with carbon black, it can increase to 25–35 MPa. It also exhibits excellent fatigue resistance and flexural endurance.
3. Good Processability: After plasticizing, it has high plasticity, making it easy to mix, calender, and extrude.
4. Excellent Adhesion: It bonds easily with other materials.
