What is the composition of polyurethane coated wheels?

What is the composition of polyurethane coated wheels?
This is what we are going to tell you today. In fact, in life, each product is composed of many different small components. This composition process is a point worthy of our recommendation.
Polyurethane coated wheels will explain these processes to you today:
Pouring polyurethane is a mixture of two liquid polymer compounds, one is a prepolymer, the other is a curing agent, the two liquid polymer compounds are fully stirred by manual or mechanical methods, and then injected into the corresponding Special molds, after sulfur, chemical curing, can obtain the required wheel shape, classified from the chemical composition of the prepolymer, polyurethane elastomers are mainly divided into two types: polyester type and polyether type. The outer ring of the mechanical wheel is usually coated with polyurethane polyurethane elastomer.
After polyurethane products, polyurethane mainly deals in polyurethane cleaners, polyurethane products; polyurethane casters, bearing rubber-coated wheels; various types of polyurethane conveyor rollers, rubber-coated rollers, polyurethane (PU) cutting rollers, polyurethane coatings, and various types of conveyor bearing coatings Wheels, polyurethane air-tight cushions, polyurethane rollers, various cushion blocks, polyurethane (PU) pipe cleaners, antistatic and flame retardant polyurethane (PU) rollers, corrugated polyurethane (PU) expansion blocks, polyurethane rubber rollers, polyurethane Transmission rollers and so on.
