Polyurethane, Polyethylene and Poly urea
Polyurethane Elastomers are a range of extremely diverse materials and we engineer, by either spinning, spraying or casting enabling, Australian Mining Products and Service, to develop and produce a wide range of low quantity, high quality reliable products to suit every operational application in a diverse range of circumstances.
We offer, cold cast, Spray or trowel able grades and qualities that are specifically tailored for short turn-around specific site emergency repairs. We offer our autoclave cured hot cast polyurethane or spray material to meet exactly site operational criteria as well as optimum site performance. Our techniques as well as our wide range of start out chemicals can deliver products that achieve specific hardness’s required as well as physical properties, to meet the requirement of the operational parameters.
We mould from simple products of any volume to complex solutions using Thermoplastic polyurethane (TPU) that is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
Polyurethane Advantages & Properties
Polyurethane is an extremely versatile elastomer used in countless applications worldwide. Polyurethane’s mechanical properties can be isolated and manipulated through creative chemistry which creates a number of unique opportunities to solve problems with performance characteristics unequaled in any other material.
Wide Range of Hardness
The classification of hardness for polyurethane relies on the prepolymer’s molecular structure and can be manufactured from 20 SHORE A to 85 SHORE D
High Load Bearing Capacity
Polyurethane has a high load capacity in both tension and compression. Polyurethane may undergo a change in shape under a heavy load, but will return to its original shape once the load is removed with little compression set in the material when designed properly for a given application.
Flexibility
Polyurethanes perform very well when used in high flex fatigue applications. Flexural properties can be isolated allowing for very good elongation and recovery properties.
Abrasion & Impact Resistance
For applications where severe wear prove challenging, polyurethanes are an ideal solution even at low temperatures.
Tear Resistance
Polyurethanes possess high tear resistance along with high tensile properties.
Resistance to Water, Oil & Grease
Polyurethane’s material properties will remain stable (with minimal swelling) in water, oil and grease. Polyether compounds have the potential to last many years in subsea applications.
Electrical Properties
Polyurethanes exhibit good electrical insulating properties.
Wide Resiliency Range
Resilience is generally a function of hardness. For shock-absorbing elastomer applications, low rebound compounds are usually used (i.e. resilience range of 10-40%). For high frequency vibrations or where quick recovery is required, compounds in the 40-65% resilience are used. In general, toughness is enhanced by high resilience.
Strong Bonding Properties
Polyurethane bonds to a wide range of materials during the manufacturing process. These materials include other plastics, metals and wood. This property makes polyurethane an ideal material for wheels, rollers and inserts. In most cases, the bond strength to metals will exceed the tear strength of the urethane.
Performance in Harsh Environments
Polyurethane is very resistant to extreme temperature, meaning harsh environmental conditions and many chemicals rarely cause material degradation.
Mold, Mildew & Fungus Resistance
Most polyether based polyurethanes do not support fungal, mold and mildew growth and are therefore highly suitable for tropical environments. Special additives can also be added to reduce this in polyester materials as well.
Color Ranges
Varying colour pigments can be added to polyurethane in the manufacturing process. Ultraviolet shielding can be incorporated into the pigment to provide better colour stability in outdoor applications.
Economical Manufacturing Process
Polyurethane is often used to manufacture one-off parts, prototypes or high volume, repeat production runs. Size ranges vary from a few grams to 100’s of KG’s
Short Production Lead Times
Compared to conventional thermoplastic materials polyurethane has a relatively short lead time with significantly more economical tooling costs.
