Use in Cold Storage and Refrigeration Cold storage and refrigeration facilities require exceptional insulation and airtight sealing, making PU foam sealant an ideal material for these applications. It is widely used to seal joints, panels, and penetrations in cold rooms, refrigerated warehouses, and transport containers. By preventing air leakage, PU foam sealant helps maintain consistent low temperatures and reduces energy loss, which is critical for preserving food, pharmaceuticals, and other temperature-sensitive products. Its closed-cell structure provides excellent thermal insulation and moisture resistance, minimizing the risk of condensation and ice formation. PU foam sealant also adheres well to metal and composite panels commonly used in cold storage construction. Fast curing and strong bonding allow for efficient installation and maintenance, reducing downtime in operational facilities. The durability of PU foam sealant ensures long service life even under constant temperature cycling. As demand for reliable cold chain infrastructure continues to grow globally, PU foam sealant plays a vital role in ensuring efficiency, safety, and energy conservation.
PU Sealant vs PU Foam Sealant: What’s the Difference – PU sealant and PU foam sealant are both made of polyurethane; however, they do different things. PU Sealant (in paste or bead form): Put immediately into joints or seams. It hardens into a rubbery, stretchy material. Used a lot for automobile sealing, glazing, and expansion joints. PU Foam Sealant (Expanding Foam): Given out in pressurized cans or spray rigs. It can grow to be 30 to 60 times its liquid volume to plug holes. Often used for insulation, window frames, and filling gaps. Types of PU Sealants – Component PU Sealants: They cure with moisture, are straightforward to use, and work on most construction joints. Component PU Sealants: Before using, combine the resin and hardener. Make things dry faster and work better.
PU (Polyurethane) foam sealant is widely recognized as a key material for improving energy efficiency across multiple industries. Its ability to expand and fully fill gaps, cracks, and voids makes it highly effective in preventing unwanted air leakage. In buildings, uncontrolled air movement is one of the main causes of energy loss, and PU foam sealant directly addresses this issue by creating an airtight barrier. Once cured, the foam forms a stable structure with low thermal conductivity, reducing heat transfer between indoor and outdoor environments. This helps lower heating and cooling demands, resulting in reduced energy consumption and operating costs. Beyond construction, PU foam sealant is also used in appliances, industrial equipment, and transportation systems where temperature control is critical. Its long-term dimensional stability ensures that the seal remains intact over time without shrinking or cracking. Manufacturers such as Shuode focus on producing foam sealants with consistent expansion rates and uniform cell structures to maximize insulation performance. As global industries continue to emphasize energy conservation and sustainability, PU foam sealant remains an effective and economical solution.
Use of PU Foam Sealant in Appliance Manufacturing Household and commercial appliance manufacturers rely on PU foam sealant for insulation, sealing, and assembly efficiency. It is commonly used in refrigerators, freezers, water heaters, ovens, and air-conditioning units to seal joints and improve thermal performance. By reducing heat transfer and air leakage, PU foam sealant helps appliances operate more efficiently and consume less energy. The foam’s ability to bond to metal and plastic components ensures reliable sealing throughout the product’s lifespan. In addition to insulation, PU foam sealant also provides vibration reduction, contributing to quieter appliance operation. Its fast curing time supports high-speed production lines and automated application systems. The lightweight nature of the foam allows manufacturers to enhance performance without increasing product weight. As appliance efficiency standards become more stringent worldwide, PU foam sealant continues to play a crucial role in meeting regulatory requirements and consumer expectations for durability, efficiency, and comfort.
