On August 7, 2026, the 7th National Conference on Supply and Demand Negotiation of Quartz Sand for Building Materials was grandly held. This conference brought together representatives from the entire industrial chain, including quartz sand raw materials, quartz stone panels, polymer resins, equipment manufacturing, and research institutions. They conducted in-depth discussions on raw material supply and demand matching, green production, process innovation, and breakthroughs in high-end products. Fangxin Resin (Anhui) Co., Ltd. was invited to attend the conference. President Lu Xudong delivered a keynote speech titled "High-performance Unsaturated Resin Promotes the Value Enhancement of Quartz Stone Industry", focusing on sharing the research and development achievements of the special resin for quartz stone heat transfer printing, using material innovation to solve the pain points of new processes, and helping domestic quartz stone enter the high-value-added market.

Currently, the quartz stone industry is accelerating its transformation and upgrading. Thermal transfer printing technology, as a crucial approach to achieving realistic natural stone patterns on the plates, enriching product designs, and creating differentiated products, is being adopted by an increasing number of plate manufacturing enterprises. However, this technology requires a 180-220℃ high-temperature heat pressing process, which poses strict demands on the high-temperature resistance, heat yellowing resistance, thermal stability, and toughness of the substrate resin. Lu Xudong pointed out in his report that the industry is generally facing practical challenges: After the general-purpose unsaturated resin undergoes high-temperature transfer printing, it is prone to defects such as darkening and dulling of the plate surface, distorted patterns, cracking of the plate, peeling, and warping. This directly leads to a high rate of product scrap, hindering the large-scale mass production and quality improvement of thermal transfer printed quartz stone. Coupled with the three persistent pain points in the industry - product homogeneity, residual harmful solvents in some resin systems, and insufficient supply of high-end supporting resins - domestic thermal transfer printed quartz stone is unable to fully unleash its market competitiveness.

In the speech, Lu Xudong focused on introducing the specialized technical research conducted by Fangxin Resin on the thermal transfer printing scenario. Centering on three major aspects: the thermal stability of resin molecules under high-temperature conditions, the infiltration property of quartz powder, and the low-volatile and environmentally friendly formulation, the R&D team systematically optimized the resin molecular structure, the acid-alkali monomer ratio, and the high-temperature resistance and anti-yellowing additive system, developing the heat transfer printing quartz stone-specific unsaturated resins FX-8801, FX-8802, and FX-8803 series products. This resin is suitable for high-temperature processing conditions of 190-210℃ in thermal transfer printing, effectively inhibiting the phenomenon of high-temperature yellowing; it also takes into account high hardness and moderate toughness, reducing the risk of plate cracking and warping during the hot pressing process; at the same time, it optimizes the adhesion between the resin and the quartz sand powder, ensuring clear transfer pattern texture, high color reproduction accuracy, excellent pattern adhesion, and reducing smudging, blank edges, and other undesirable problems. In terms of environmental protection, the product's optimized formulation system reduces the addition of toxic and harmful solvents, takes into account the occupational health and safety of the production workshop, and conforms to the industry's green development orientation.

"For heat transfer quartz stone to truly break through, it cannot rely solely on equipment and transfer consumables. The base material resin is the underlying key factor," said Lu Xudong. Traditional general-purpose resins cannot meet the high-temperature conditions of the new process, which is also the core reason why many board enterprises have difficulty increasing the yield rate after installing heat transfer production lines. Fangxin heat transfer-specific resin aims to fill the gap in domestic material production, allowing domestic board enterprises to produce high-quality heat transfer quartz stone stably without completely relying on imported resins. This will enable them to escape the low-price competition, create distinctive patterned boards with premium pricing, and expand into high-end application markets such as home decoration, industrial background walls, and countertops. "

At the same time, he emphasized that the upgrading of the heat transfer printing quartz stone industry cannot be achieved without the synergy of the entire industrial chain. The purity and grading of quartz sand aggregates, the resin bonding system, the heat transfer printing ink, and the process parameters need to be mutually matched. Fangxin Resin will continue to collaborate with heat transfer printing equipment manufacturers and sheet material manufacturers, conduct raw material - equipment - process compatibility tests, and continuously iterate resin products based on the actual production conditions of the customer's line, and output a complete set of material application solutions.

This negotiation meeting has established an efficient platform for upstream and downstream parties to connect and communicate. Through this theme sharing, Fangxin Resin showcased its technical capabilities in Fangxin Thermal Transfer Resin to the industry, and conducted technical exchanges and demand matching with numerous quartz sand and quartz stone enterprises. In the future, Fangxin Resin will continue to focus on the research and development of high-performance unsaturated polyester resins, address the pain points of new quartz stone processes, and continuously provide environmentally friendly, stable, and high-performance resin products. Through material innovation, it will promote the high-quality development of China's artificial quartz stone industry.
