Polyurethane Foams
Characteristics
Polyurethane foams are lightweight, durable and cushiony materials, which vary in density and stiffness. Besides being resistant to heat and chemical attack, they are also a shock and sound absorber, as well as a thermal and electrical insulator. Furthermore, polyurethane foams can be easily processed to create a virtually infinite variety of colored, cut, bored, sealed and other forms.
Usage
Flexible Polyurethane Foams
Transport - roof material, seat cushions for cars, aircraft and trains
Domestic appliances: cushions for beds, sofas and other upholstery/furniture
Rigid Polyurethane Foams
Building and construction materials - insulation
Industrial materials - insulation for oil/gas tank facilities
Domestic appliances - insulation for refrigerators
Others - core material for surfboards
Polyurethane Elastomers
Characteristics
Polyurethane elastomers are extremely versatile materials offering a wide range of special characteristics. They have a particularly high level of elasticity, tensile strength and elongation. Besides being superior in their rubber elasticity, abrasion resistance and ozone resistance, these products also have good resistance to oil and gasoline. Other characteristics include being heat resistant (-20°C to 80°C) and hydrolysis resistant, as well as having shock absorbing abilities.
Usage
Industrial use - wide range of rollers, tubes, belts, packaging, gear, insulation rubber, pipe linings and coatings for textile surfaces, and insulators for electrical products
Others - shoe soles, plastic hammers, cutting boards, adhesive sheets, and solid tires
Polyurethane Coatings
Characteristics
Polyurethane coatings adhere well to most materials, forming excellent protective layers that are abrasion resistant, water resistant and chemical resistant.
Usage
Transportation - Cars, aircraft, trains
Architecture - Interior/exterior of houses and buildings, bridges, furniture
Home appliances and other everyday applications
Ink - gravure
Polyurethane Adhesives
Characteristics
Besides having the ability to adjust properties to optimal flexibility levels, polyurethane adhesives also provide good adhesive strength to substrates. They are also water, oil and chemical resistant.
Usage
Food packaging, shoes, wood, building and construction, automobiles, lamination (dry lamination and anchor coating for extrusion lamination)
Binders
Characteristics
Offering good mechanical and chemical strength, polyurethane binders are the backbone of high-strength adhesive systems for the bonding of particulate materials and other materials. The bonding strength and molecular weight of polyurethane binders can be readily adjusted to meet the needs of the particular application.
Usage
Magnetic recording media - music tapes, videotapes, magnetic cards
Wooden boards - particle boards, MDF, vinyl boards
Building and construction materials - rubber chip binders, anchor bolts
Polyurethane Waterproof Materials and Elastic Sealants
Characteristics
Polyurethane chemicals can be mixed and applied at the site and left to harden at room temperature, producing a seamless, waterproof elastic film. These products are optimal for use in construction and refurbishing applications. Other applications include sealants used for surfacing of athletic tracks, and many more.
Usage
Architecture - Waterproof coating for roofs and insulation sashes
Transportation - Front and rear glass windows of automobiles
Polyurethane Leathers
Characteristics
Polyurethane leathers are lightweight and comfortable materials. They cannot be damaged by water, are easily maintained, are abrasion resistant and can be dry-cleaned. They also have strong oil, lubricant, and chemical resistance. Polyurethane leather ranges from soft to hard, and is available in a wide variety of colors and patterns.
Usage
Synthetic leather - handbags, shoes, belts, surface treatments for all kinds of leather goods
Medical Equipment
Characteristics
As polyurethane adapts well to the human body, it is being used in artificial organs and dialysis equipment. In addition, it is utilized in water purification/filtration systems.
Usage
Artificial organs - artificial heart pump, artificial kidney
Medical equipment - haemodialysis machines
Polyurethane Elastic Fibers
Characteristics
Spandex fiber, which is made from polyurethane elastic fibers, is similar to natural rubber, but offers superior weight, strength, abrasion resistance, weather resistance, chemical resistance, and dyeability performance properties.
Usage
Spandex
