PU is the abbreviation of Polyurethane, the Chinese name is polyurethane for short.As, only a simple modification of the formula, you can get different density .Elasticity .Rigidity and other physical properties.At present, it has replaced a large number of fiberglass insulation materials .Wood.Traditional rubber products, etc.

What is PU foam?

Integral foam means once formed, also called molded foam, once completely with polyurethane foam, polyurethane (Polyurethane) is polyether polyol and polyisocyanate and other chemical raw materials polymerization, polyurethane has black material and white material, where the isocyanate: O = C = N-R there are more than N, generally with an unpleasant odor of liquid, toxic, isocyanate on human health hasThe isocyanates are harmful to human health, some people feel dizzy.Headaches.Nausea.Shortness of breath, and even a very few people vomit blood immediately after smelling this odor, and in serious cases will immediately pass out.

pu paint

PU paint is the collective name of all polyurethane paints, its film-forming method is natural, without special technology.Adhesion.Sealability.PU paint is the best choice for home decoration because it is stronger than other types of paint in terms of environmental friendliness, adhesion, flexibility and film transparency.Because PU paint can be dried and cured at low temperature, it can be used in a wide range of temperatures, so the construction season is relatively long.

how to wash pu leather jacket

I.Tools / raw materials ammonia.A mixture of alcohol and water weak alkaline detergent special leather cleaner II.Method / step PU leather jacket how to wash method 1: manual cleaning: manual cleaning refers to a way of scrubbing the stains on the surface of the leather directly with a clean cotton cloth or cotton ball dipped in cleaning agent.It is mainly for a part of the leather jacket stained with oil and dirt and not easy to clean, mainly on this point to wipe. how to wash PU leather jacket method 2: Of course we can not always parts of the leather jacket cleaning, in the long run then it is easy to make a part of the leather jacket color darkened and not the same as other parts.This time we have to take machine dry cleaning.Machine dry cleaning is a way of washing clothes in a dry cleaning machine with organic solvents.There are many advantages of this type of cleaning, not only high efficiency, but also more comprehensive cleaning, not only can be cleaned on the surface of the leather jacket, the dirty inside of the leather jacket can also play a role in cleaning, and his ability to remove dirt than the manual cleaning clean.

pu leather

PU leather is the epidermis of polyurethane composition.Nowadays, it is widely used to make luggage.Clothing.Shoes.PU leather is also good or bad quality, good PU leather is even more expensive than real leather, good shaping effect and bright surface!Challenge natural leather because of its excellent natural characteristics is widely used in the production of daily necessities and industrial products, but with the growth of the world's population, human demand for leather multiplied, the limited number of natural leather has long been unable to meet this demand.To solve this contradiction, scientists began to research and develop artificial leather decades ago.More than 50 years of research history is the process of artificial leather.Synthetic leather to challenge the natural leather process.

pu is what material

Pu is a polymer compound, which is made by the reaction of isocyanate group and hydroxyl group. pu is an artificial synthetic material, with the texture of leather, very strong and durable, it is different from artificial leather. pu synthetic leather is used to replace PVC artificial leather, its price is higher than pvc artificial leather from the chemical structure, it is closer to leather fabric, it does not use plasticizer to achieve the soft nature, so itIt doesn't become hard and brittle, at the same time, it has the advantages of rich colors and patterns, and the price is cheaper than the leather fabric, so it is welcomed by the consumers.
