Guangdong Yihao Chemical Technology Co., Ltd. was founded in 2012 in Shantou City, Guangdong Province. It is an enterprise specialized in the R&D, production, sales and service of polymer polyester, polyurethane and polyurethane adhesives. By continuously driving technological innovation and maintaining top-tier production standards, we have positioned ourselves as a reliable global partner for industries requiring high-performance chemical formulations.
Yihao Chemical has successively established branches in many overseas countries:
Switzerland is globally recognized for its uncompromising standards in precision engineering, pharmaceutical manufacturing, and sustainable industrial practices. The Swiss industrial landscape demands raw materials that offer not only exceptional performance but also strict compliance with European and domestic environmental regulations, such as REACH and the Swiss Ordinance on Materials and Articles (SR 817.023.21).
Saturated polyester resins play a pivotal role in this highly specialized market. From high-end watchmaking components requiring ultra-thin protective coatings to the robust architectural structures in the Swiss Alps that demand weather-resistant powder coatings, our products meet the precise physical and chemical properties required by Swiss manufacturers.
Furthermore, Switzerland’s commitment to a circular economy and green energy transitions has accelerated the demand for eco-friendly, low-emission, and bio-based resins. Our research and development efforts focus heavily on creating solvent-free and waterborne saturated polyester resins that align perfectly with the sustainable vision of Swiss industries.
The company’s polyester, polyurethane and polyurethane adhesive products under the brands of "Yihao" and "ASTER" are well-known in China, Southeast Asian countries such as Thailand, Malaysia and Indonesia, as well as Türkiye, Russia and other nations.
Our advanced research facilities focus on synthesizing saturated polyester resins with precise glass transition temperatures (Tg) and hydroxyl values, tailored for high-performance coatings and inks.
We rigorously test our adhesives and resins under Simulated Environmental Chambers to guarantee long-term performance in real-world industrial settings.
Its adhesive products are widely applied in food packaging, pharmaceutical packaging, metal packaging, household appliance panel films, building material decorative films, automotive window films and interior films, as well as new energy sectors including solar photovoltaic backsheet films, lithium battery aluminum-plastic composite films and high-temperature insulating films for motors. Its polymer polyester products are used in coatings, inks, new materials, metal sheet coatings and other fields, making the company a designated supplier for numerous domestic and international brands.
Our saturated polyester resins and polyurethane adhesives are optimized to solve unique challenges faced by key Swiss industrial sectors.
Exterior architectural coatings in Switzerland must withstand intense UV exposure at high altitudes and freezing winter temperatures. Our saturated polyester resins provide excellent weatherability, color retention, and chalking resistance for Swiss building facades.
Switzerland is a global hub for life sciences. Our high-purity polyurethane adhesives ensure laminate integrity for blister packs and sterile medical pouches, offering superior chemical resistance and high-temperature sterilization tolerance.
Swiss watchmaking and precision micro-electronics require ultra-thin, highly insulating protective coatings. Our specialized polyester resins deliver exceptional dielectric properties and adhesion to delicate metal substrates.
For Swiss consumer goods and food packaging companies, production efficiency is key. Our fast-curing polyurethane adhesives are designed for high-speed laminating machines, reducing curing times and maximizing throughput.
Guangdong Yihao Chemical combines large-scale manufacturing capability with boutique R&D precision. We understand that Swiss clients require consistent quality, prompt technical support, and transparent compliance documentation. Here is how we deliver on those expectations:
In 2022, Yihao Chemical established Jiangxi Yihao Chemical Technology Co., Ltd. in Ganzhou City, Jiangxi Province, building a production base featured by automation, intellectualization and informatization. The base strictly implements the ISO 9001 Quality Management System, ISO 45001 Occupational Health and Safety Management System and ISO 14000 Environmental Management System. Adhering to the EHS green development philosophy, the company fully integrates environmental protection, health and safety standards into the entire production and operation system.
Equipped with a professional R&D team composed of doctors and post-doctors, an experienced production and QC team, as well as a global sales and service team, Yihao Chemical upholds the corporate culture of "Transcending Limits, Striving for Perfection". Standing at the forefront of the industry, we commit ourselves to technological innovation, with the core goal of developing personalized, environmentally friendly and new energy-related products, and dedicate to providing premium services for customers at home and abroad.
As Europe transitions towards a carbon-neutral economy, the chemical industry is undergoing a massive transformation. Saturated polyester resins are increasingly replacing traditional epoxy resins due to their superior safety profile (BPA-free) and lower environmental footprint. In Switzerland, this trend is driven by consumer demand for safer food packaging and green building certifications (such as Minergie).
Our research division is actively developing bio-based saturated polyester resins synthesized from renewable plant-derived monomers. These bio-resins maintain the same mechanical properties, chemical resistance, and flexibility as their petroleum-based counterparts while reducing carbon footprint by up to 30%.
In addition, the shift towards waterborne and powder coating systems is accelerating. Waterborne saturated polyester resins significantly reduce solvent emissions during application, helping Swiss manufacturers comply with strict volatile organic compound (VOC) taxation rules. By choosing Yihao Chemical as your supplier, you secure a future-proof supply chain that aligns with the evolving regulatory landscape of Switzerland and the European Union.
