Qingdao Maisheng New Materials Co., Ltd. was established in 2014 and has been developing for 12 years. Initially, our core product was super absorbent polymer (SAP), with an annual capacity of 1,500 tons. Back then, we operated in a 3,000-square-meter workshop equipped with just two production lines. Over the past 12 years, through unremitting efforts in market expansion and product innovation, we have gained widespread recognition from customers worldwide. Today, our production workshop has expanded to 50,000 square meters with 30 advanced production lines, and the annual capacity has soared to 10,000 tons. By continuously expanding our professional team, we have successfully entered the international market and diversified from a single product to a full range of upstream and downstream products for the cable industry.
 
2024 marks a milestone year for Maisheng. We have transformed from small-scale production to building an integrated cable industrial chain. The production area has expanded from 5,000 to 50,000 square meters, and our product range has evolved from a single category to a comprehensive portfolio covering industrial, agricultural, and daily life applications. Based on a solid domestic market foundation, we have expanded our business to the Asia-Pacific, European, and American markets, achieving an annual export volume of 5,000 tons and made Chinese intellectual shining in the world.
 
We adhere to strict quality control standards and boast a professional R&D team of 5+ engineers dedicated to product innovation and customization. Our products comply with international standards such as ISO 9001, TUV, meeting the stringent requirements of global markets.
