FAQ

 

Q: What is blend polyol?

A: Blend polyols are complex combinations of various polyols, which are substances identified by having multiple hydroxyl (-OH) functional groups. These functional groups play a fundamental role in initiating the formation of polyurethane polymers through a chemical process referred to as the polyurethane reaction

Q: Why the Use of "Blend" Polyols?

A: The"blend" is the amalgamation of multiple polyols to generate a mixture with distinct properties. The blending procedure incorporates polyols that vary in molecular weights, chemical structures, and reactivity. This diverse amalgamation of polyols empowers manufacturers to produce foams endowed with a more extensive spectrum of properties compared to what could be attained using a single polyol.

Q: What is the classification of Blend Polyether?

A: Polyurethane rigid foam blended polyethers for thermal insulation are typically composed of components such as polyethers, foam stabilizers, catalysts, blowing agents, flame retardants, etc.
Depending on the type of blowing agent, they can be classified into several main types, including high-fluorine, non-fluorine 141b, and non-fluorine all-water types and so on
Generally, the polyether blend appears as a light yellow or reddish-brown viscous transparent liquid with no condensates, thickeners, uneven substances, or mechanical impurities.
In terms of foaming processes, rigid foam blended polyethers can be categorized into pour-in-place, spray, and foam-in-place types.
Based on their applications, they are commonly used in packaging, refrigerators, high-temperature resistance, general industrial insulation, and sandwich panel construction composite polyethers.

Q: What is the production process of the spray foam insulation blend polyols?

A: Rigid foam blended (polyether/polyester) polyols are homogeneous mixtures prepared by manufacturers, combining monomeric polyether/polyester polyols (one or more types) with amines, metal (Sn, K) catalysts, silicone oil surfactants, crosslinking agents, blowing agents, flame retardants, storage stabilizers, and various additives. The types and amounts of each component are determined based on the processing properties, foam performance requirements, and foaming characteristics.
For spray foam insulation polyol, a strong catalytic system is formed by compounding with highly catalytic triethylenediamine, dibutyltin dilaurate, and others. This catalytic system results in a rapid foaming process, forming a milky, gel-like, non-sticky material with a short curing time and a powerful expansion force. The dosage of tin catalysts, in particular, should be carefully controlled to avoid a sharp increase in reaction material temperature, which could lead to scorching, burning, or cracking of the final product.

Q: What’s the the testing parameters for the Blend Polyether Polyols For Rigid Polyurethane Foam?

A: To the Blend Polyether Polyols For Rigid Polyurethane Foam usually need test the performance appearance, brown viscous liquid viscosity, density, foam physical propertie, cast type spray type milky white time, drawing time, non-stick time, foaming parameters bulk density, compressive strength, water absorption, thermal conductivity, dimensional stability, etc.

Q: What’s the mainly usage of the PU rigid foam?

A: 1. Refrigeration and freezing equipment for industries such as home appliances and food,polyether polyols used for refrigerators.
2. Insulation for industrial equipment and pipelines,polyether polyol used for pipe insulation,PU pipe insulation
3. Building materials,spray foam insulation
4. Transportation and maritime materials.
5. Simulated wood materials and sports and leisure equipment,polyurethane wood imitation
6. Sealing materials and mining materials,polyether polyols used for mining industry
7. Military and aerospace applications.

Q: What’s the Testing Standards for the Blend Polyether Polyols For Rigid Polyurethane Foam?

A: 1. GB/T 30916-2014: spray foam for insulation Blend Polyether Polyols
2. HG/T 4961-2016: Polyether Polyols Used for Refrigerators and Freezers
3. HG/T 4960-2016: Polyether Polyols Used for Sandwich Panel
4. HG/T 4395-2012: Polyether Polyol Used for Water Heaters
