** POLYURETHANE **
Today's broad use of Polyurethan. Not only in the field of industry, such as for a
refrigerator, a water bottle (thermos), gas pipelines, and oil refineries. Now,
Polyurethane products have turned into alternative building material which has many
advantages but it also can be found on various objects around us. For example, in liquid
coatings and paints, like the tough elastomer roller blade wheels, insulation made from
tough, flexible foam is soft, elastic fibers, or as intact skin.
Aside from being a heat barrier, polyurethane material also has advantages as retaining
water pipes, refrigerated transport equipment, as well as coolers for industry and
households. Polyurethane materials are very similar to the foam, is also widely used for
flotation and energy management
Today, the building houses, buildings, and other facilities, demanding materials
berkualias tall, strong, light weight, good appearance, easy to install, durable, and
reliable. With the needs of the people of Indonesia are increasing each year, the quality
of building materials and appearance of the building must be reliable. That causes
Polyurethane manufacturers consistently advised the developers / consultants to jump
on this material
The mass load-owned, polyurethane has a density that does not impose on a building.
Therefore, very lightweight polyurethane. Its specific gravity is only about 36 Kg/m3.
The results of testing by the manufacturer indicates that the propagation coefficient of
heat generated by the polyurethane only about 0.017. That's a sign that once attached
polyurethane, which is forwarded to the heat capacity of a building is very little
The advantages of Polyurethan are:
• Heat Proofing, Water Proofing and Sound Proofing
• With 1 Inch Thick 40-45% reduces the influence of the outside temperature (heat
reduction = 40-45% per 1 inch)
• Easily print, cut and stained
• Rigid, Rigid and Lightweight
• The material is coated to be stronger
• Has excellent adhesion properties
• Ease of installation
• Durability is good (10 years warranty)
Polyurethane is formed from the reaction of polyols (alcohols with more than two
reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate to
the availability of suitable catalysts and additives. Due to the diversity and breadth of
the range diisocyanate polyol can be used to produce polyurethane, while the magnitude
of the diversity of materials can be produced to meet specific application needs.
Most of the material is a thermoset polyurethane; not be melted and reshaped as
thermoplastic materials. Polyurethane is also present in various forms, such as flexible
foam, hard foam, proof coating chemicals, adhesives, and insulation, as well as
elastomers.
Hard polyurethane foam used as insulation material in buildings, water heaters,
refrigerated transport equipment, and cooling for industrial and domestic. The foam is
also used for flotation and energy management.
Flexible polyurethane foam used as softeners in carpet and upholstery furniture,
mattresses, and car. Foam is also used as packing of goods.
Polyurethane adhesives and insulation used in the construction, transportation, boats,
and other uses that require strength, moisture resistance and long-lasting nature of the
polyurethane. The term "polyurethane elastomer" includes products such as
derivatives, thermoplastic polyurethane, cast elastomers, and the products of Reaction
Injection Molded (RIM). These materials include a wide variety of uses, from shoes and
wheels skate to home supplies, athletics track, as well as electronic instruments.
Polyurethan usage in various fields.
Polyurethane is one of the most reliable materials at this time. Its usefulness varies from
flexible foam in furniture upholstery to hard foam insulating walls and roofs,
thermoplastic polyurethane used in medical equipment and shoe lining, adhesives,
insulation and elastomer used in flooring and interior of the car. To get more
information on polyurethane, see the following explanation:
1. 1. Industry
• Flexible Foam (Foam bending)
Reliability of flexible polyurethane foam form and its use can be found in mattresses,
furniture, car interiors, carpet layers, and packaging. Foam can be made into almost
any kind of forms with varying degrees of violence. In addition, the foam is lightweight,
durable, useful, and convenient.
• Rigid Foam (Foam Hard)
Hard foam and foam polyisocyanurate foam is one of the most famous in the world,
energy-efficient, and reliable insulation. This type of foam significantly reduced fuel use
and cost of manufacture to produce commercial and household equipment safer, better
use, and more comfortable throughout the world.
• Thermoplastic Polyurethane
Thermoplastic polyurethane (TPU) offers many combinations of equipment building
and processing applications. Thermoplastic polyurethane is very elastic, flexible,
resistant to abrasion, impact resistant and weather resistant. TPU can be colored or
copies in various ways, and its use adds to the overall durability of a product.
• Coatings, Adhesives, Sealants and Elastomers
Polyurethane coating makes a product look better and last longer. Polyurethane
adhesives offer advantages in strong adhesiveness. Polyurethane insulation provides
sekatan tight. Polyurethane elastomers can be molded into almost any shape, is lighter
than steel, offering a high pressure recovery, and can be resistant to many
environmental factors.
2. Daily needs
• Atomotif
Polyurethane is used on your car overall - at the usual places like the foam that makes
you comfortable car seat, as well as in some places you might not expect.
• Building and Building
The house is now demanding materials are high quality, strong, lightweight, great view,
easy to install, and are durable as well as reliable. With a number far exceeding the 1.5
million homes were built in the United States per year, the quality of building materials
and look to be very reliable, making the reason why builders consistently turned to
polyurethane
• Coatings, Adhesives, Sealants and Elastomers
Diversity on the usefulness of polyurethane coatings, adhesives, insulating, and
elastomers not only promote the traditional production methods but also greatly extend
the life of the goods covered.
• Mixed Wood
Some modern materials is now a combination of synthetic and natural materials.
Polyurethane plays an important role in modern materials such as wood mixture.
• Furniture
Polyurethane, mostly in the form of flexible foam, is one of the most popular materials
used in home furnishings such as furniture, mattresses, carpets and upholstery.
• Ships
Sailing and fishing is becoming very popular in many circles. This hobby will be more
smoothly when in tunjang by adequate facilities, such as a comfortable boat.
• Medical
Polyurethane is commonly used in a number of medical devices including catheters and
tubes in general use, hospital beds, operating room drapery fabric, gauze, and also on
injecting equipment.
