Polyurethanes are a remarkably versatile polymer which can range from rigid to flexible, solid to lightweight foams. Polyurethanes are all around us, playing a vital role in many industries - from ship building to footwear, construction to automotive. They appear in an astonishing variety of forms, a variety that is ever increasing.
Unrivaled insulating values, exceptional abrasion resistance, superior adhesion, high sound and energy absorption and low part weights are some of the unique properties that our customers take advantage of, when manufacturing with polyurethane systems.
The following section presents a brief summary of a range of applications and typical properties that can be achieved, with different polyurethane systems.
Single Component
Single component urethanes are widely used in the adhesive coating and sealant industries. They offer exceptional adhesion to a variety of substrates, good chemical and abrasion resistance as well as being strong and flexible. Polyurethane adhesives are used in the rubber crumb binder; carpet underlay binder, automotive interiors, windshield bonding and as textile laminates.
Elastomers
Elastomers are solid urethane components which offer excellent flexibility, elastisicity, chemical and abrasion resistant properties. They can also range from very soft (fishing lures, sorbothane, rubber bands), to very hard (golf ball covers, bone models).
Flexible Foams
Flexible foams can also range in densities similar to rigid foams but are used for applications such as mattresses, pillows, flexible filters, head rests, sound absorption and shoe soles to name a few. Integral skins are a special type of flexible foam which forms a tough elastomeric membrane surrounding a low density foam core. These are used applications such as steering wheels, spa head rests, and automotive dashboards.
Rigid Foams
Rigid foams ranging from low density, suitable for insulation application to high density, suitable for structural components. Rigid Foams are widely accepted by industry for their excellent insulation values and high strength to weight properties.
Thermoplastics
Pacific Urethanes is the exclusive Australian distributor for the Texlan™ range of thermoplastic urethane which is excellent for producing products with high elasticity, excellent abrasion resistance, high tensile strength, excellent oil resistance and low temperature resistance.
