Customer reviews

Emily · Pharmaceutical Distributor

In the pharmaceutical industry, maintaining precise temperature control is critical. These polyurethane insulation panels have been instrumental in ensuring our temperature-sensitive medications are stored safely. The panels are easy to clean and maintain, and their performance has been reliable over time. They've become an essential part of our cold chain logistics.

James · Construction Project Manager

We recently completed a cold storage warehouse using these polyurethane insulation panels. The panels were easy to install and provided excellent insulation right from the start. The project was completed on time, and the client was very satisfied with the energy efficiency and temperature stability. These panels are now our go-to choice for cold storage construction.

David · Cold Storage Engineer

From a technical perspective, these low-temperature polyurethane panels are impressive. The material's thermal conductivity is low, and the closed-cell structure ensures minimal heat transfer. We've used them in several cold storage projects, and the feedback from clients has been consistently positive. The panels also resist moisture and mold, which is crucial for long-term use.

Product Description

Product features:

This product adopts modified MDI foaming system, ensuring good structural stability at -60℃ low temperature without embrittlement or cracking. The surface is coated with food-grade antibacterial and mildew resistant coating, complying with FDA food contact material standards, suitable for fresh food and medical cold chain scenarios. The steam barrier rate is as high as 99%, avoiding internal frosting affecting insulation performance. The enterprise mouth splicing design is matched with sealing strips to achieve zero-gap installation, preventing cold and hot air penetration. Compared with traditional extruded boards, the insulation performance is improved by more than 30%, effectively reducing the operating energy consumption of cold chain systems.

Low-Temperature Cold Chain Polyurethane Insulation Board

Product specifications:

The standard size is 1100mm (length) ×2200mm (width), with optional thicknesses of 80mm/100mm/120mm/150mm. The base material density is 42±2 kg/m³, with a thermal conductivity of 0.020 W/(m·K) at 25℃ and ≤0.025 W/(m·K) at -60℃. The water absorption rate is ≤0.2% (v/v). The fire rating complies with GB8624 Grade B1 and NFPA 285 standards. The temperature resistance range is -60℃ to 80℃. The food-grade antibacterial coating complies with FDA 21 CFR Part 178.3297 standards. The weight of a single board is about 18-33 kg depending on the thickness. The packaging uses waterproof stretch film + solid wood pallets, with about 40 boards loaded per pallet.

Product application:

It is suitable for various low-temperature cold storages, fresh cold chain storage centers, medical cold chain transport compartments and freezer container insulation layers. It can also be used for the insulation enclosure structure of polar scientific research stations. It can stably maintain the cold chain environment temperature, reduce the operating time of refrigeration equipment, reduce the overall operating cost of cold chain logistics, and ensure the transportation and storage quality of fresh food and medical products.

Frequently Asked Questions (FAQ)

Q：What are the key advantages of low-temperature cryogenic polyurethane insulation panels?

A：Low-temperature cryogenic polyurethane insulation panels offer superior thermal conductivity (0.022-0.028W/m·K), moisture resistance, and structural stability at -50°C to 80°C. Ideal for cold chain logistics, they reduce energy loss by 30% compared to traditional materials.

Q：Why choose polyurethane over polystyrene for ultra-low temperature insulation?

A：Polyurethane outperforms polystyrene in cryogenic environments with: 1) 20% lower thermal conductivity, 2) -196°C brittleness resistance, 3) seamless bonding preventing cold bridges, critical for LNG/medical cryopreservation applications.
