  • An Overview of Cast Polyurethane

    Do you know the benefits of cast polyurethane? Cast polyurethane is a versatile material that is highly resistant to chemicals and abrasions. The plastic is stable in water, and is easy to process and inexpensive to produce. Urethane can be as hard as a golf ball or softer than natural rubber. The way that the plastic is created is by the reaction between a prepolymer containing reactive isocyante groups and a curative that contains hydroxyl groups. This mixture creates a solid elastomer plastic that can then be transformed into thousands...

  • When Supply Is In Demand: Cast Urethane

    There are times when a company needs to produce a model for a product they manufacturer, or a model of building they would like to construct, or even a mock-up of a new invention or advancement in design they have come up with. There are all kinds of ways to accomplish this kind of creation. Some will use wood, some metal, others plastic or even rubber. But there are ways in which companies can create prototypes or models without resorting to some of the more complicated and/or expensive ways to...

  • Some Helpful Methods for Urethane Casting

    When companies are searching for a material with strength, versatility, long service life, high impact resistance, elastic memory, noise reduction or heat and chemical resistance, often they turn to urethane. Urethane castings are able to provide all of these qualities and more such as high abrasion, cut, tear, oil, ozone and radiation resistance. The material is lightweight, can be easily molded, is non-conductive and non-sparking, provides good load bearing, has a broad hardness range and can even be colored. These characteristics make it an important part of industries ranging from...

  • The Protection of Urethane Bumpers

    Protection comes in many forms depending on the context. For a celebrity, the best protection comes from a human-being security guard who has serious training, strength and maybe a gun. Home protection is in the form of small mechanical systems with sensors surrounding the perimeter, which when activated alert the police that someone is on your property uninvited. For moving vehicles, protection served in the shape of a urethane bumper. Bumpers absorb the impact of an accident, protecting the person inside the vehicle as well as the rest of the...

  • Urethane Casting: The Best of the Three

    There are three major materials utilized for the mass production of many products these days, excluding the clothing market that has its own major materials to contend with. The big three are metal, plastic and rubber. Each category has its own plethora of individual stars, such as the ever popular aluminum and stainless steel in the metal category while PVC is a plastic that steals the spotlight again and again. There is one style of rubber though that is able to take on any special combination from rubber plastic or...

Industry Information

Urethane Casting

Urethane casting, technically referred to as polyurethane casting (or PU), is an elastic polymer, or elastomer, containing urethane carbamate links. From a molten liquid state, polyurethane may be fabricated or molded into low-density flexible foam, low-density rigid foam, soft solid elastomers (gel) and hard solid plastics. Valued primarily for its uses in rigid and flexible memory foams, polyurethane is extremely useful in solid plastic form as well.

Although all elastomers maintain strength and versatility in many industrial applications, polyurethane elastomers possess several advantages over other elastomers and materials. For instance, urethane casting combines many of the desirable qualities of plastic, rubber and metal with longer service life than plastics, higher impact resistance than rubber, elastic memory, noise reduction, heat and chemical resistance, and many other properties. Additional benefits of cast urethane include higher abrasion, cut, tear, oil, ozone and radiation resistance, lightweight, easily moldable, non-conductive, non-sparking, greater load bearing ability, broader hardness range and better colorability than rubber. Cast urethane products include wide variety of pneumatic seals, press tool blocks, conveyor bushings, bumpers, bowling balls and parts for a broad spectrum of industries such as construction, automotive, food processing and athletic equipment.

The raw materials of polyurethane exist in a liquid state, which allows for easy mixing and measuring in preparation for molding, which may be open casting or closed casting. Raw materials react with one another to form a pre-polymer, then during the urethane molding process, a curative is introduced to the pre-polymer in order to complete the polymeric transition. Accelerated by heat and/or pressure, the mixture is poured into a mold cavity and cured to form the final polymer. During open urethane casting, the pre-polymer and curative are heated and mixed together, poured into an open cavity and cured without the application of pressure. During closed urethane casting processes such as injection molding, the pre-polymer and curative are heated and mixed together, then injected into the closed cavity through small holes. An example of a type of urethane casting would be compression urethane casting, which is commonly used to make small polyurethane parts such as gears. Additionally, cast urethane serves better than regular plastic in many applications, as it has higher impact, low temperature, cold flow, radiation and abrasion resistance, better elastic memory and noise reduction capabilities, greater resilience and provides lower cost tooling. The cost of urethane casting is on par with the cost of rubber and typical polymer molding, giving urethane an economic advantage as well.
