As long as you choose spray-applied rigid all-water polyurethane from a reliable manufacturer, it is completely feasible, safe, and reliable for cold storage insulation applications — you can select it with confidence. Recommendations by Temperature Range: Cold Storage Type Temperature Range Recommended Specification Standard cold storage -18°C ~ -20°C High structural strength all-water PU, output yield 22–24 m³ Low-temperature cold storage Below -40°C High-strength formulation, output yield 20–22 m³ Constant temperature storage Above -5°C Any Lingdian New Materials all-water PU product series
Yes, it can be washed, but act quickly. Once all-water polyurethane fully cures, it becomes virtually insoluble and can only be removed mechanically. Best window: Uncured (within 30 minutes) Use any of the following methods: A. Dishwashing liquid + warm water + brush (safest) Uncured all-water PU is highly viscous but can be softened by surfactants + hot water. Steps: Most workwear-friendly option. B. Alcohol (75% or 95%) — swells polyurethane surface Not-fully-cured water-based PU is sensitive to alcohols. Suitable for: Alcohol-resistant fabrics (cotton, polyester, workwear materials) C. Acetone (powerful — use with caution) Significantly swells uncured PU, but: Semi-cured (1–3 hours) treatment Once all-water PU semi-cures, it becomes tough but hasn’t fully film-formed. You can try:
The water content in all-water polyurethane polyol component is actually very low, typically only around 2–4%. Too much water would cause excessive foaming → resulting in coarse, uneven cell structure and reduced strength, among other issues. So while people may assume all-water polyurethane contains lots of water and should therefore be cheaper, this is not the case. In fact, its cost is higher compared to traditional 141B polyurethane systems.
The short answer is no — higher density does not necessarily mean better insulation performance. A Simple Analogy: The Down Jacket Imagine choosing a down jacket: The Science Behind It The relationship between polyurethane foam density and insulation performance follows this exact principle. Polyurethane foam’s thermal insulation capability depends on how it impedes three heat transfer mechanisms: The cellular structure of the foam is the critical factor. Key Takeaway Therefore, selecting the appropriate polyurethane density for specific application scenarios is essential to achieve optimal thermal insulation performance.

Recently, a batch of Lingdian all-water rigid polyurethane foam has successfully completed production and quality inspection and is now ready for shipment to Saudi Arabia. The exported products adopt an environmentally friendly all-water foaming system, free of traditional blowing agents such as CFCs and HCFCs. Green, low-carbon, and performance-stable, the materials comply with the high environmental and safety standards required in the Middle East. With a high closed-cell rate, excellent thermal insulation performance, superior compressive strength, and strong weather resistance, the product is widely applicable to building insulation, cold storage projects, and industrial equipment insulation in Saudi Arabia. It is ideally suited to the region’s high-temperature, dry climate and intense sunlight conditions. From formulation optimization and production control to final product inspection, we strictly manage every stage of the process to ensure consistent and reliable quality in every shipment. This delivery not only reflects the Saudi customer’s recognition of Lingdian’s product strength, but also marks another important milestone in the company’s expansion into overseas markets and its commitment to supporting global infrastructure development. Looking ahead, Lingdian will continue to provide high-quality, environmentally friendly polyurethane solutions, contributing to global engineering projects and delivering stable, efficient, and trustworthy material support to customers worldwide.

Dongying Lingdian Chemical New Materials Co., Ltd. is a specialized chemical enterprise integrating the research and development, production, and sales of polyurethane materials. At the beginning of this year, the company planned the construction of a brand-new production base. After on-site evaluations and comprehensive comparisons across multiple regions, LiQue Town — known for its strategic location advantages and excellent business environment — was ultimately selected as the project site. Since officially signing the investment agreement and settling in March this year, LiQue Town has established a dedicated “one-to-one” service mechanism for the company. Assigned personnel have been providing continuous follow-up support, ensuring comprehensive and streamlined services throughout the entire process — from project landing to construction advancement. Ji Meiting, Deputy Director of the Economic Development Office of LiQue Town, stated:“For key projects in our town, especially high-tech private enterprise initiatives, we have established a comprehensive support mechanism. From early-stage land approval procedures to environmental impact assessments, energy evaluations, and other administrative approvals, we provide dedicated assistance and agency services. When enterprises encounter challenges related to funding, land resources, or other development needs, we actively coordinate with higher-level authorities to facilitate early implementation, accelerated construction, and prompt commencement of operations.” With the efficient support and strong backing of the local government, the Dongying Lingdian Chemical New Materials production base project is progressing smoothly and rapidly. The new facility lays a solid foundation for future capacity expansion and the company’s continued development in the polyurethane materials market.
