1. Introduction to Polyether Polyol pump system chemicals

Polyether Polyol is the main component of the Polyurethane chemical system. When combined with Isocyanate (ISO) in the appropriate ratio, the PU foam reaction mixture has a closed cell structure and heat insulation ability. The pump system helps control the amount of chemicals, mixing ratio and reaction speed.

· Production of PU insulation panels with continuous production lines suitable for many panel thicknesses.

· Pumping foam to insulate refrigerators, freezers, and refrigerators.

· Production of ice boxes, insulation boxes and water heaters.

4. Application of chemicals Polyether Polyol pump system

Production of heat-insulating PU panels

The Polyol system combined with Isocyanate creates a PU foam layer between the surface material layers, supporting insulation, increasing core hardness and reducing panel weight, used in cold storage, factories and clean rooms.

Insulate refrigerators and freezers

The mixture is pumped into the cavity between the two device shells, then expands to create a stable layer of insulating foam.

Ice box and insulation box

PU foam helps reduce heat exchange with the environment, helping to prolong cold retention time.

Insulate hot and cold water heaters

The foam layer around the inside of the bottle helps limit heat loss and maintain water temperature.

Industrial thermal insulation equipment

Can be applied in compartments and insulation details depending on product design and technical requirements.

5. Preserve and pay attention when using

Storage conditions

· Store in a dry, well-ventilated place; Avoid direct sunlight and high heat sources.

· Limit contact with water and moisture; Close the drum lid when not in use.

· Suitable storage temperature is mainly 18–29°C, some codes recommend 18–25°C; Suitable storage time is about 6 months.

Control the ratio of Polyol and Isocyanate

The Polyol/ISO ratio in the quote refers to volume. Need to adjust according to technical instructions and actual testing, avoid arbitrarily changing the ratio that affects the foam structure.

Temperature control, pumps and labor safety

Before mass production, machine pressure, material temperature, chemical feed rate and foam density should be tested and adjusted according to machine type and product thickness. Operators should use gloves, glasses and protective clothing, ensure ventilation and carefully read the TDS/SDS of both Polyol and Isocyanate.
