What is Molded Urethane?

Molded urethane is urethane that has been fabricated to form a part by introducing liquid urethane into a mold and allowing it to cure. Molded urethane products offer excellent flexibility and resistance to chemicals. They can be utilized for multiple industrial purposes, such as water treatment facilities, pressure transducers, and petroleum products.

Molded Urethane

Additives can be introduced to reduce friction, improve UV resistance, and increase flame retardation. Molded urethane products can also be utilized in small devices -- for example, washers -- to meet specific requirements.

Urethane appears as a white crystalline powder. For a reaction to occur, it must be first converted into its liquid state. After being converted into its liquid state, molded urethane products can be made by pouring or injecting liquid urethane into a mold containing the product.

When the reaction occurs, the urethane expands and hardens. To ensure lasting quality, it is necessary to carry out the curing process of the products in industrial ovens.

Molded Urethane Products

Some of the molded urethane products include:

Molded Urethane Bushings

These bushings can be utilized in high-impact areas where the loads go beyond the capabilities of plastic and bronze. They are formulated using high-performance polymers.

Concrete Urethane Molds

These molds are durable and perfectly smooth. They are less expensive and exhibit higher abrasion resistance than molds made from silicon. Urethane concrete molds are very hard and do not shrink. Their abrasion resistance allows them to be used again and again.

Molded Urethane Shock Absorbing Pads and Mounts

Urethane is a compound ideal for use in vibration dampening and shock absorption. In addition, molded urethane has a wide range of hardnesses, making these products well-suited for applications like shock/vibration absorption.

Molded Urethane Rings

These products are manufactured from high-performance prepolymers. As a result, they can meet or exceed the highest standards, reducing downtime and costs for replacement.

Types of Molded Urethane

Some types of molded urethane include:

Compression Molded Urethane

This type of molded urethane is produced by pouring liquid urethane into a mold and allowing it to cure inside a compression press. This technique is well suited for components that must maintain dimensional accuracy and repeatability. Molded urethane produced through compression is rigid, flexible, resistant to wear, and durable.

Compression Molding

Low Pressure Injection Molded Urethane

This type of molded urethane is produced by injecting liquid urethane into a closed mold at low pressure. This technique is utilized in cases where component shape, component size, or tooling configuration would make the process of compression molding impractical. Injection molded urethane products are intricate and highly precise.

Injection Molding

Open Cast Molded Urethane

This type of molded urethane is made by pouring liquid urethane into an open mold. The mold will then be cured in an oven or heated table. Molded urethane products produced in this way are high-performance.

Urethane Cast Parts

Reaction Injection Molded Urethane

Molded urethane made by this technique is made by injecting isocyanates and polyols into a closed mold. This will trigger a chemical reaction that causes the expansion of the material to form the finished product.

Applications and Benefits of Molded Urethane

Some applications and benefits of molded urethane include:

Applications of Molded Urethane

Molded urethane products can be used in the following industrial sectors:

  • Building and construction
  • Transportation
  • Textiles
  • Fiberglass
  • Steel and aluminum
  • Seals and wipers
  • Machinery and foundry

Benefits of Molded Urethane

  • Molded urethane is considerably tougher compared to plastic.
  • The one-step molding process used in producing molded urethane is more economical than the process of machining blocks of plastic.
  • The process of compression molding produces large and fairly intricate parts.
  • Compression molding also produces molded urethane at a low cost.
  • Molded urethane is available in a wide range of hardness to meet cost and performance requirements.
  • Molded urethane exhibit excellent abrasion and tear resistance, which prevents the fast aging of products
  • It is also resistant to chemical agents like hydraulic oil, gasoline, ozone, silicone oils and greases, and pure aliphatic hydrocarbons.
