Application fields and development prospects of elastic polyurethane materials

Polyurethane elastic materials belong to block polymers, that is, polyurethane macromolecules are composed of "soft segment" and "hard segment" and form a microscopic phase separation structure.

Among them, the hard segment (derived from isocyanate and chain extender) is dispersed in the soft segment phase region (derived from oligomer polyol) to play the role of physical crosslinking point,

Therefore, compared with other synthetic rubbers (elastomers), polyurethane elastomers have superior strength and wear resistance, and can maintain high elongation when the hardness is high.

Polyurethane elastomers in a narrow sense refer to cast polyurethane elastomers (CPU), thermoplastic polyurethane elastomers (TPU) and mixing polyurethane elastomers (MPU),

It accounts for 10% or slightly less of the total amount of polyurethane, among which CPU and TPU are the main polyurethane elastomers, and their difference lies in factors such as production process and chain extender.

This kind of traditional polyurethane elastomer is also called "polyurethane rubber", which belongs to a kind of special synthetic rubber. High-performance polyurethane elastomer is the material with the best wear resistance among all synthetic polymer materials.

Known as the "King of Wear Resistance", it is widely used in many fields, and new applications are still being expanded.

Polyurethane elastomers can be used to replace metal, plastic and ordinary rubber in some fields.

Compared with metal materials, polyurethane elastomer has the advantages of light weight, low noise, wear resistance, low processing cost and acid corrosion resistance. Compared with plastics, it has high toughness,

High wear resistance and other advantages. Compared with general rubber, polyurethane elastomer has the advantages of wear resistance, cutting resistance, tear resistance, high load bearing capacity, ozone resistance, etc., and is easy to manufacture, can be potted and casted, and has a wide range of hardness.
