QHB-265 Combined Polyether for Cold Chain Transportation

1. Description

This product is a special combined polyether for the cold chain transportation field, formulated based on Huntsman TEROL® recycled polyester polyol patent technology, and is the core raw material for the insulation layer of cold chain equipment such as refrigerated trucks and refrigerated containers. It is a pale yellow viscous liquid with good compatibility, controllable foaming speed, and high foam closed cell rate (≥95%), featuring excellent thermal insulation performance and fire safety. Its fire rating reaches the highest standard for organic materials (Class B1), which can effectively retard the spread of fire, reduce smoke emission, and ensure the safety of cold chain goods and personnel.

Adopting an environment-friendly foaming system, it is fluorine-free, odorless, and does not damage the ozone layer, suitable for the long-term outdoor use of cold chain transportation equipment. It can maintain good dimensional stability in extreme temperature environments of -40℃~60℃, significantly reduce refrigeration energy consumption during cold chain transportation, and extend the shelf life of perishable goods.

2. Specification

3. Application

This product is mainly used in the cold chain transportation field, and is ideally suitable for the foaming of insulation layers of various refrigerated trucks, refrigerated containers, and insulation boxes, including the filling and insulation of refrigerated truck compartments, inner walls of refrigerated containers, and portable cold chain insulation boxes.

It can be widely used in scenarios such as food cold chain, pharmaceutical cold chain, and fresh cold chain, adapting to various cold chain needs such as long-distance transportation and short-distance distribution. It can effectively maintain a stable temperature control environment of -20℃~10℃ inside the cold chain equipment, reduce the operating load of refrigeration equipment, and lower energy consumption. At the same time, it can be used for the repair of insulation layers during the renovation and maintenance of cold chain transportation equipment, compatible with two foaming processes: spraying and casting, and suitable for the production and maintenance needs of cold chain equipment of different specifications.

4. Storage

1. Storage Environment: Store in a cool, dry, and well-ventilated warehouse, with the temperature controlled at 5℃~25℃. Avoid high and low temperature environments (crystallization may occur below 0℃, and deterioration is likely above 30℃).

2. Sealing Requirement: Packed in sealed iron drums. Ensure the drum lid is tightly screwed during storage to prevent air and moisture from entering. Use up the product as soon as possible after opening; seal the unused part and store it in a low-temperature environment.

3. Handling Requirement: Handle with care during transportation to avoid collision and damage to the iron drums. Dumping and rolling are prohibited to prevent product leakage.

4. Taboos: Strictly prohibit contact with open flames, high temperatures, and strong oxidants; do not store with acidic or alkaline substances; keep away from flammable and explosive items.

5. Disposal of Expired Products: Perform performance testing on expired products. Unqualified products shall be entrusted to professional institutions for harmless treatment; random discarding and dumping are strictly prohibited.
