What Is Polyurethane Sheet?
High-density polyurethane sheet is an insulation system based on a very rigid polyurethane foam, which has a high density.
It can be cut in any size, shape, and thickness to meet specific needs.
The sheets are versatile and can be tailored to fit various applications.
To use high-density polyurethane sheets effectively, it's essential to evaluate the surface you want to apply them to, considering the required resistance.
You'll also need to determine the necessary thickness and density to achieve the desired insulation.
Types and Sizes
High density PU foam sheets are available in a range of densities, typically between 30-120 kg/m³.
They come in various sizes, from small rolls for crafting and prototyping to large sheets for industrial applications.
The thickness of the foam can vary from 1-50 mm, depending on the intended use and desired level of support or cushioning.
These factors make high density PU foam sheets a versatile material for a wide range of applications.
PU Types
PU types are categorized into several groups based on their chemical structure and properties.
Polyurethane (PU) is a versatile material that can be made from a variety of isocyanates and polyols, resulting in different types of PUs.
PU foams are commonly used in furniture and mattresses, while PU coatings are used for their durability and scratch resistance.
PU foams can be further divided into two main types: flexible and rigid.
Flexible PU foams are used in applications where flexibility is required, such as in shoe soles and seat cushions.
Rigid PU foams are used in applications where rigidity is necessary, such as in insulation and automotive parts.
PU coatings come in different types, including solvent-based and water-based.
