FAQ

Q: What’s advantage of BEIQIAO polyurethane prepolymer?

A: Long gel time
High tensile strength
Low abrasion

Q: What is the Polyurethane Prepolymer?

A: Polyurethane prepolymer is an intermediate product in the production of polyurethane. It is formed by the partial reaction of a polyol (a substance with multiple hydroxyl groups) with an excess of diisocyanate. This prepolymer typically has reactive isocyanate (NCO) end groups and is used to produce various polyurethane products by further reacting it with a curative or chain extender.

Q: What's the key characteristics of polyurethane prepolymers?

A: 1.Composition:
Polyol: Can be either a polyester polyol or a polyether polyol.
Diisocyanate: Common diisocyanates include toluene diisocyanate (TDI), methylene diphenyl diisocyanate (MDI), and hexamethylene diisocyanate (HDI).
2.Reactive End Groups:
The prepolymer has reactive isocyanate groups (NCO) that can react with other compounds (typically polyols or amines) to form the final polyurethane product.
3.Viscosity:
Prepolymers can range from low to high viscosity depending on their formulation and intended application.

Q: What ‘s the applications of the pu prepolymer ?

A: 1.Used to make castable elastomers with high resilience and toughness, such as industrial wheels, rollers, and seals.
2.Used in both rigid and flexible polyurethane foam formulations for applications such as insulation, cushions, and packaging.
3.Utilized for their strong bonding properties and flexibility.
4.Employed in protective coatings for floors, automotive parts, and various other surfaces.

Q: What’s the advantages of the pu prepolymer ?

A: 1. The properties of polyurethane prepolymers can be tailored by varying the polyol and diisocyanate types, allowing for a wide range of mechanical and physical properties in the final product.
2.Products made from polyurethane prepolymers are known for their excellent abrasion resistance, toughness, and load-bearing capacity.
3. Can be used in a variety of applications across different industries, from automotive to construction to consumer goods.

Q: What’s the tubular continuous reaction technology to produce the polyurethane prepolymer?

A: 1. Raw materials need to be prepared in a certain ratio
2. Raw materials usually need to be mixed before entering the tubular reactor
3. The mixed raw materials pass through the tubular reactor and undergo polymerization according to the preset temperature, pressure and time conditions.
4. During the reaction, the reaction temperature needs to be strictly controlled to ensure that the polymerization reaction can proceed smoothly and control the quality of the product.
5. Once the reaction is completed, the product will flow out of the reactor through the pipeline. The product may require further processing, such as cooling, solidification or separation.

Q: What’s the production process for the tubular continuous reaction technology to the polyurethane prepolymer?

A: Raw materials --> feed pump --> mixer --> tubular reactor --> reactor outlet pump --> cooler --> product
