Introduction:
At Saltech, we pride ourselves on representing the finest elastomers in the UK for their polyurethane (PU) products. Our commitment to quality and innovation has established us as a trusted name in the industry. Today, we want to delve into the fascinating world of urethane and highlight why it stands out as a superior material for various applications.
What is Urethane?
Urethanes, commonly known as polyurethanes, are a versatile family of elastomers that were initially developed as ‘artificial rubbers’ during World War II. These materials offer a unique combination of the advantages found in rigid plastics, metals, and ceramics, while also providing the flexibility and elasticity of rubber. This makes polyurethanes an exceptional choice for a wide range of industrial applications.
Types of Polyurethanes
Polyurethanes are available in two main forms: thermosets and thermoplastics.
Thermoset Polyurethanes
These are created by blending a resin and a curative, resulting in high-performance engineering properties. The process involves chemical cross-linking, which must be completed before the mixture cures. This method allows for the molding of large or complex-shaped parts with relatively inexpensive molds. Commonly referred to as cast polyurethanes, they offer several advantages including:
- Excellent resilience
- High toughness and durability
- Very high load-bearing capacity
- Outstanding abrasion resistance
- Good machinability
- Resistance to oils, solvents, water, and ozone
Thermoplastic Polyurethanes
These are available in pellet form and can be re-melted and molded using injection molding or extrusion. While they share some properties with thermoset polyurethanes, their applications are typically limited by the size and shape of the molded parts.
Applications and Advantages of Cast Polyurethanes
Cast polyurethanes can be customized to achieve a combination of properties tailored for specific applications. Some of the key benefits include:
- High tear strength and cut resistance
- Low compression set
- Good impact resistance
- Non-marking
- Mold, mildew, and fungus resistance
- Flex fatigue resistance
- Excellent electrical properties
Specialized Polyurethane Compounds
Different formulations of cast polyurethanes, such as those based on TDI, MDI, PPDI, polyethers, polyesters, and polycaprolactones, provide a wide range of application possibilities. For instance:
- Polyethers are ideal for dynamic applications and environments exposed to moisture, making them suitable for die-forming pads, fork lift tires, and roller coaster wheels.
- Polyesters offer superior cut, tear, and abrasion resistance, as well as better resistance to oil and solvents, making them perfect for hydraulic seals, scraper blades, and rolls for graphic arts.
