Urethane is a man-made polymer that provides superior protection on wood and metal, but its plastic appearance can be unsightly. It has higher chemical and impact resistance, making it suitable for automotive and countertop finishes. Urethane products for wood come in oil- and water-based varieties, with water-based being non-toxic. However, the plastic-like appearance may detract […]
Urethane and epoxy are used in various industrial products, with differences in color, chemical resistance, flexibility, and texture. Urethane is resistant to UV light and remains the same color, while epoxy turns yellow over time. Epoxy is highly resistant to chemicals, while urethane wears faster. Epoxy is stronger but can break on moving surfaces, while […]
Urethane foam is a versatile man-made material used in bedding, packaging, footwear, and insulation. It is made from polyurethane and can be manufactured to different densities. It is commonly used in mattresses and insulation due to its low lambda value. There are some health concerns associated with its use, but evidence is controversial. Urethane foam […]
Urethane sheets are versatile and durable, with different types distinguished by size, color, and hardness. They can be manufactured through extrusion or thermoset processes and used for various industrial and residential applications, including sound insulation and material handling equipment. Some sheets have metal or fabric backing, while others are wax-free or dual-layered. The manufacturing process […]
Polyurethane is a versatile material used for its toughness, durability, and elasticity. Urethane products can replace plastic, metal, or rubber due to their resistance to abrasion, oils, solvents, and weather. Urethane wheels are commonly used in machinery and household items such as skateboards and escalators. They are more durable than metal or plastic wheels and […]
Urethane rollers are used to transport materials and parts along a track with minimal damage. Idler rollers slow down objects, while drive rollers provide power. Conformal and segmented rolls are also available, as well as transfer rollers for printing. Customizable options are available online. Urethane rollers are a part of a machine used to send […]
Tips for successful urethane casting include careful material selection, proper tool preparation, pre-testing the casting material, pouring into low or detailed areas first, and removing air from the casting. Different materials and tools may be required for different applications. Pre-testing can identify any issues with the casting material, and removing air can prevent air bubbles […]
Urethane bumpers are plastic pads used in manufacturing to line conveyor belts and equipment. They are cost-effective, non-marking, and easy to install, but vulnerable to extreme temperatures and chemicals. They are not suitable for all applications and require careful consideration before use. Urethane bumpers refer to hard plastic knobs or pads used in manufacturing and […]
Urethane is a synthetic polymer with elastic and stretchy properties, superior to rubber due to high load capacity, tear resistance, and tolerance to grease, oil, and ozone. Urethane bushings are used in heavy trucks’ suspension, steering mechanisms, and towing hitches for their durability and vibration reduction benefits. The polyurethane polymer, or urethane, belongs to a […]
Proper urethane molding requires thorough mixing, removal of air bubbles, and careful pouring. Vibration can help remove bubbles, and curing should be allowed to progress slowly. Careful demoulding is also important. Improper urethane molding practices can lead to less than desirable results, but there are a few tips that can help improve the process. All […]
Cast urethane is a popular choice for industrial and manufacturing applications due to its quick mold process and strength-to-weight ratio. However, the quality of the finished product is limited by the prototype and the vulcanized rubber mold has a limited lifespan. Larger parts may require longer curing times and excessive temperatures can cause degradation. Cast […]
Urethane rubber is a strong, durable, and inexpensive material used in industrial manufacturing for mold making. It is easy to mix and apply, and can be poured, brushed, or sprayed onto hard casting materials. When used with a sealant and release agent, it can replicate sculptures or stamp designs in concrete. The resulting mold is […]
