TOPROPAN
Product Description
PU (polyurethane) is a multi - functional polymer material with good thermal insulation performance, mechanical properties, etc.
PUR (polyurea) performs excellently in thermal insulation, waterproofing and other aspects, and its molecular structure gives it relatively good stability.
PIR (polyisocyanurate) is a high - performance thermal insulation material. Its thermal insulation effect is better than that of ordinary polyurethane, and it is especially suitable for low - temperature environments such as cold storages with high requirements for temperature control.
The cold storage sandwich panels made of these materials are mainly used for the construction of cold storages. The sandwich panel structure sandwiches the thermal insulation material between two layers of metal plates (such as PPGI/PPGL/ stainless steel, etc.). This structure enables the cold storage to have good thermal insulation performance, which can effectively reduce the heat transfer from the outside to the inside of the cold storage, thereby reducing the energy consumption of the refrigeration equipment in the cold storage and ensuring the stability of the low - temperature environment in the cold storage, which is conducive to the preservation of freshness and quality of items such as food and medicine that need to be stored at low temperatures.
Product Advantage
High - efficiency Heat Insulation: The PU, PUR, and PIR materials themselves all have good thermal insulation properties. Among them, the thermal insulation effect of PIR is particularly outstanding. In a cold - storage environment, this means that it can reduce the amount of external heat entering the cold - storage interior, thereby reducing the running time and energy consumption of refrigeration equipment. For cold storages with extremely strict temperature requirements, such as those storing vaccines, special pharmaceuticals, or high - end fresh foods, these materials can keep the temperature fluctuation within a very small range, ensuring that the quality of the stored items is not affected by temperature changes.
Waterproof and Moisture - proof: The sandwich panels made of PU/PUR/PIR perform excellently in terms of waterproofing. In a cold - storage environment, water vapor condensation may occur. The waterproof and moisture - proof characteristics of the sandwich panels can prevent water vapor from seeping into the insulation layer and avoid the decline of the insulation performance.
Light in Weight and High in Strength: Polyurethane itself has a relatively low density, usually 40 ± 2 kg/m³, but its strength is higher than that of rock wool with a density of 100 kg/m³. During the installation and use process, the sandwich panels can withstand certain external forces and are not easily deformed or damaged.
