At this opportunity, we will introduce some types of polyurethanes

Flexible Polyurethane Foam Foam:
This type of polyurethane foam is used to make all sorts of consumables and commercial products, including fabrics, office furniture and home appliances, car interior (trim), under layer, shoe insoles and special packaging designs.

Flexible foam can be made with various shapes and strengths, in a variety of lightweight, durable, well-equipped and comfortable form.

Flexible polyurethane foam covers 30% of North American polyurethane market

Rigid Polyurethane Foam:
Hard polyurethane foam is another popular polyurethane type, which is one of the most popular and most effective types of polyurethane foam in the world. This type of foam is for various purposes, including all kinds of polyurethane foam that can be used to save large amounts of energy. According to the American Energy Organization, about 56 percent of the energy consumed for cooling and heating residential homes in the United States is wasted, which is a huge waste of energy. To maintain a moderate temperature and a low level of noise in homes and commercial properties, builders have turned their polyurethane foam into polyurethane foam.

These foams are highly insulating materials that can be used to insulate ceilings and walls, insulate windows, doors, and insulators (sealants) to prevent air entrainment. Also, hard polyurethane foam (rigid foam) is used as thermal insulation at a density of 37 to 43 kg / m 3 in the production of sandwich panels, insulators, insulating walls of tanks and insulation of chemical transfer tubes. Other types of hard polyurethane insulators with high growth rates and rapid formation systems are used in the form of foam spray in the insulation of building structures.

Foam of hard polyurethane in a density (from 70 to 700 kg per cubic meter) as a decorative foam in the production of various types of Styrofoam, wood foam, furniture parts and other special applications requiring hard and light materials. Is used.

Coatings, adhesives, sealants and elastomers
(Coatings, Adhesives, Sealants and Elastomers)
The use of polyurethane in the production of coatings, adhesives, sealants and elastomers (CASE) offers a wide and growing range of applications and applications. Polyurethane coatings can improve the appearance of products and increase the life span of products.

The polyurethane adhesives have a stronger connection, and the polyurethane sealants are more compact and tight. Polyurethane elastometers can come in any shape, lighter than metals, are capable of returning from high stress and resistant to environmental factors.

Thermoplastic Polyurethane Polyurethane
Polyurethane Thermo Plastic has a lot of physical properties and applications. This material is very elastic, flexible and resistant to abrasion, impact and weather. TPUs can be painted and made in a variety of ways and can enhance overall product durability. Like most polymers, TPUs are thermoplastic and are available in granular form, and after melting and injection, they can produce the desired product.

TPU is a thermosetting elastomer. In addition, this material can be used in connecting, detaching, impacting and compression molding equipment. It can be in the form of a vial or coating solution and is suitable for a wide range of construction methods. TPU can provide a significant number of compounds with physical properties, which makes it a highly flexible material that can be used in dozens of buildings, cars and shoes.

Injection Molding (RIM)
Car bumper, electrical parts of houses and computers, and telecommunication equipment. Some cases made by polyurethane are based on the use of reactive injection molding (RIM). Adding design flexibility is part of the RIM’s polyurethane process and process, which is usually done by using a conventional injection molding process, such as thick and thin sections of the wall, material enclosure and foam cores. In addition to higher strength and lower weight, RIM polyurethane can display thermal resistance, thermal insulation, dimensional stability and high level of dynamic properties. Vehicles, buildings, appliances, furniture and entertainment and sports equipment are few of the uses of RIM technology.

Polyurethane Binder
Polyurethane binders are used to attach a large number of particles and fibers to each other. The first one is used in the manufacture of wooden panels, rubber or elastomeric floor coverings, and sand casting in the casting industry. The high volume of polyurethane binders is at the multilayer board production plant. These wooden panels are used in structural and floor coverings, building houses, joists and beams and store panels. Rebond foam (sponge foam scrap that is split in a special mill and after mixing with special adhesives in the rebound sponge manufacturing machine is thoroughly mixed and then molded into the mold and pressurized depending on the required density and rebound foam (Under the carpets) are made of polyurethane fibers and chemicals to connect foam wastes, which are usually flexible foam of polyurethane, to become laminate
