I. Provincial R&D Platform, a Solid Foundation for Innovation
Relying on the provincial-level R&D platform "Zhejiang Longxin Chemical Polymer New Materials High-Tech Enterprise Research and Development Center", the company systematically carries out technological research and development and achievement transformation. The center was recognized by the Department of Science and Technology of Zhejiang Province in 2022, marking that the company's R&D system, innovation capability and talent team have obtained authoritative provincial recognition, providing a solid institutional and platform guarantee for sustainable innovation.
II. Excellent Talent Team Leading Technological Breakthroughs
The company has a highly professional and rationally structured R&D team. As of 2025, the company has 33 technological innovation personnel and continues to introduce high-end talents. We have specially hired Professor Guo Ming, who holds a PhD in Chemistry, as the technical leader to lead the R&D of new unsaturated polyester resins, ensuring the forward-looking nature of R&D directions and the advancement of technical routes.
III. In-depth Industry-University-Research Cooperation, Gathering Cutting-edge Wisdom
We firmly believe that open cooperation is an accelerator for innovation. The company has established long-term and stable strategic cooperative relations with many well-known universities and research institutions at home and abroad to jointly tackle key technical problems in the industry:
Cooperation with Zhejiang A&F University: Jointly undertaking the science and technology project of "Longquan City Revealing the List and Taking Command", and successfully developing a new flame-retardant unsaturated polyester resin under the guidance of Professor Guo Ming, with relevant invention patents obtained.
Cooperation with Zhejiang University of Technology: Jointly tackling cutting-edge technologies such as organic phosphine modification and phosphonium styrene-based modification, jointly applying for and obtaining a number of core invention patents, and the cooperative achievements have been declared for science and technology awards.
Through industry-university-research collaboration, we closely integrate cutting-edge academic achievements with industrialization needs, significantly improving the performance and added value of products.
IV. Fruitful Intellectual Property Achievements Demonstrating Technical Strength
Continuous R&D investment has yielded fruitful results. The company has made a comprehensive intellectual property layout in the fields of synthetic technology, production equipment, environmental protection treatment and downstream applications of unsaturated polyester resins.
Core patent achievements (partial list):
"A Low-Density SMC Sheet and Its Preparation Method" (Invention Patent)
"Cured Product of Organophosphine-Modified Unsaturated Resin and Polyhalogenated Compound and Its Preparation Method" (Joint Invention Patent with Zhejiang University of Technology)
"A Microcapsule Flame Retardant, Flame-Retardant Unsaturated Polyester Resin and Its Preparation Method" (Joint Invention Patent with Zhejiang A&F University)
"Production Equipment for Unsaturated Polyester Resin" (Invention Patent)
"A Resin Waste Recycling Device" (Utility Model Patent) and many other process and equipment patents.
Up to now, the company has 7 valid invention patents, 8 utility model patents and 2 design patents, with a number of invention patents under application, forming a solid technical barrier.
V. Innovation-Driven Application, Technology Empowering Products
Our R&D achievements have been successfully transformed into high-end products with market competitiveness. The newly developed unsaturated polyester resin products have excellent properties such as high reactivity, high viscosity, high smoothness and degradable recycling, and are widely used in high-end fields such as electrical appliances, industry, transportation and urban facilities, creating value for customers with innovative technologies.
