With the increasing demand for energy efficiency and passenger comfort, water based spray rigid PU foam is gaining attention as a reliable solution in the transportation industry insulation materials sector. Designed as a lightweight and high-performance material, water based spray rigid PU foam offers an effective alternative to traditional insulation systems used in buses, rail vehicles, and other transport equipment.
This advanced spray polyurethane foam system is widely used to create a seamless and airtight sealing layer inside vehicle compartments. By eliminating gaps and joints, water based spray rigid PU foam significantly reduces heat loss, external noise, and vibration, contributing to a quieter and more comfortable passenger environment.
Key Performance Advantages of Water Based Spray Rigid PU Foam
One of the main advantages of water based spray rigid PU foam is its lightweight structure, which helps reduce the overall weight of vehicles while maintaining excellent insulation performance. This is particularly important in modern transportation systems where energy efficiency and fuel savings are critical.
In addition, the material provides strong adhesion to various substrates, ensuring stable bonding without the need for additional fixing methods. Its spray application allows for easy construction, even on complex surfaces, forming a continuous layer without seams.
The open cell PU foam structure delivers excellent sound absorption, making water based spray rigid PU foam highly effective in noise reduction applications. At the same time, it offers reliable thermal insulation and fire-resistant properties, meeting safety and performance requirements in public transportation.
We have the blend polyol for open cell pu foam BQ 8243
When use , the thickness of one gun spray foam should not exceed 50 mm. If over 50mm, which may cause foam charring or spontaneous combustion and poor foam performance.
It is suggested that spray next layer of the foam after the internal temperature of last spray foam blow 25℃. And the maximum thickness spray during 24hperiod is 203mm(8inches).
Like most of foam product, foam made by BQ8243 is combustible. An thermal barrier must be installed in accordance with approved construction standards.
The service temperature of the foam with BQ8243 is between -60~80℃ .
Direct contact with BQ8243 type blend polyol can lead to moderate eye irritation and mild skin irritation, which can cause skin allergies. Repeated inhalation of high concentration of volatile gas will cause respiratory allergy, and should be treated immediately. Anti- inflammatory and anti-allergic treatment measures should betaken.
Please be careful in the operation to prevent contact with the skin and splash into the eye, please wear the necessary protective equipment (gloves, protective goggles, working clothes, etc.).
Once splashed on the skin or the eye, rinse with water immediately for at least 15 minutes, and the skin is washed with soapy water. Please seek medical treatment immediately after swallowed.
