WHY PU AND NOT LEATHER

PU is abbreviated from Polyurethane, a chemical man-made material which can provides leather feel. In the handbag material tag, you will find the words such as new material, faux leather. Most of them are made of PU material. Why are PU handbags getting more and more popular?

Why polyurethane is an excellent insulant?

Rigid polyurethane foam demonstrates versatility both through its physical strengths and mechanical properties. These qualities enable it to be used in a wide variety of multi-functional building products which combine insulation with load-bearing, sealing, impact resistance, weight and space-saving, together with ease of maintenance.Low thermal conductivity. Effective insulation in all types of buildings plays a vital role in the conservation of non-renewable fossil fuels, which reduces emissions of carbon dioxide gas released by the burning of fuels for energy and therefore reduces global warming.

Strength
Rigid polyurethane foam provides a high level of compression and shear strength, which is further enhanced by bonding with facing materials such as metal or plasterboard.

Processability
Rigid polyurethane foam can be made either under continuous block or batch factory production, or by on-site mixing for spray and injection purposes.

Adhesion
During the short period between mixing and final curing, rigid polyurethane foam is extremely adhesive, which allows it to bond effectively with a wide range of building facings. The adhesion is so strong that the bond strength is usually higher than the tensile or shear strength of the foam.

Compatibility
Rigid polyurethane foam is compatible with a large number of building facings, including paper, foil, glass fibre, aluminium, plasterboard, plywood and bitumen. These can complement the inherent strengths of the foam, enabling use as semi-structural panels and cladding and allowing foam to accept cosmetic finishes such as plaster to operate effectively as moisture barriers in conditions of high humidity.

In-situ stability
Rigid polyurethane foam can be used in applications which experience exceptional extremes of temperature, from -200°C to +100°C.

Water absorption
The water vapor permeability of rigid polyurethane foam is low and is enhanced in most building applications by the incorporation of a moisture barrier of polyethylene film or aluminium foil.

Fire properties
Like all organic building materials - wood, paper, plastics, paints - rigid polyurethane foam is combustible, although its ignitability and rate of burning can be modified to suit a variety of building applications and it can be formulated to meet the relevant national regulations.

Rigid polyurethane foams are usually used at lower thicknesses than other insulants, which means that their heat or fuel contribution to a fire is low compared to other, thicker insulating materials. The overall fire performance of an insulation panel can be significantly enhanced by the material that is used to face the panel - for example, steel.

Independently monitored, large-scale tests of buildings incorporating rigid polyurethane and polyisocyanurate (PIR) foam insulation carried out in the USA and Europe have concluded that, properly used, these materials do not add to the severity or serious hazard of fires.

Lightness
At low densities (e.g. 30kg/m3), the volume of polyurethane polymer in rigid polyurethane foam is around 3 per cent. The remaining 97 per cent of the foam is gas trapped within the cells, which provides the low thermal conductivity properties.

The lightness of the foam is an important aspect in terms of transportation, handling and ease of installation.

Chemical resistance
Rigid polyurethane foam provides excellent resistance to a wide range of chemicals, solvents and oils.

Other reasons:

Price
If any new material wins the market, price must be one of the most important factors. Although you could find the high end PU bags are more expensive than the leather bags, mostly PU bags are much cheaper. Why? PU is a man-made material whose ingredients are less expensive than leather. How is PU made? It has two core layers: one is the base layer which can be textile or leather. The other is the additive layer from chemical materials. If leather-based, it is usually low quality part or leftover from leather bag materials.

Vibrant Color
As mentioned above, the top additive layer can provide a great color dye base. The color is easily attached and durable. Furthermore, the vibrant colors catch hand bags shoppers’ eyes.

Multiple Grains
You love crocodile grain, tree leaves, or foot print on your handbag surface. The easy-molded feature makes your dream come true. If you are a handbag fan, you can definitely find more amazing grains on the bags.

Durability
Compared to the previous handbag material PVC, PU handbags have a softer surface and they can be used for a long time without erosion. Plus you have no need to regularly care for your PU bags like the leather ones. Save your time and enjoy your fashion life at the meantime.

Leather Feel
One more advantage is that PU can provide the same leather feel as the genuine leather. Also, PU bags can have the same or even better air permeability. With the improved finishing touch, your PU handbags can be soft touch at an affordable price.
