What is the density of PU material?
Generally, the density of PU material is about .25g per cubic centimeter/kloc-0.

Polyurethane materials are widely used in many fields of national economy because of their properties. The product application fields involve light industry, chemical industry, electronics, textiles, medical treatment, architecture, building materials, automobiles, national defense, aerospace, aviation and so on.

Polyurethane sealant has many characteristics: wide adjustable range of performance and strong adaptability; Good wear resistance; High mechanical strength; Good adhesion; Good elasticity and resilience, can be used for dynamic joints; Good flexibility at low temperature; Good weather resistance and long service life 15~20 years; Good oil resistance; Anti-biological aging; The price is moderate.

Extended data:

PU material is formed by the reaction of isocyanate groups and hydroxyl groups. Because of its flexibility, strong ductility and good air permeability, it is widely used in the clothing field, and its price is low, so it is loved by everyone.

Pu polyurethane has better performance than PVC, so garment manufacturers like to use it to make clothes and make fast imitation leather clothes. Most of the familiar bags are made of pu.

Pu fabric, that is, leather-like fabric, is a synthetic material with the characteristics of genuine leather texture and durability. Pu material is characterized by good physical properties, good bending resistance, good softness, high tensile strength and good air permeability.
