Microcellular urethane (Poron®) is a closed cell urethane foam. The special properties of microcellular urethane foam make it a desirable material from which to manufacture parts with a variety of uses. CRG offers custom parts from microcellular urethane foam that service an array of applications. This blog highlights the properties and characteristics of microcellular urethane foam, as well the custom manufactured parts which CRG can provide.
Microcellular urethane is a soft, pliable foam material with excellent resistance to compression set. Specific characteristics of microcellular urethane include the following:
Excellent compression set resistance.
Good resistance to chemicals.
Flame retarding, without the use of special additives.
Easy-to-work – the material cuts cleanly in fabrication processes, can be treated with adhesives or bonding agents, and can be easily fashioned into end-use parts and products.
Available in a wide range of formulations and thicknesses, making the material readily adaptable for a variety of end-uses.
Due to its inherent characteristics, microcellular urethane foam is a good material choice for applications and end-uses which require gasketing, sealing, cushioning, dampening, and impact protection. Applications that can use custom parts from microcellular urethane foam include those in the automotive, communications, and electronics industries, as well uses in industrial equipment.
Applications that CRG can service with custom parts from microcellular urethane foam include the following:
Automotive and mass transit applications. CRG can produce parts for vehicle interiors and exteriors from microcellular urethane foam. End-uses include gasketing, sealing, and NVH (noise, vibration and harshness) suppression.
Custom parts from microcellular urethane foam can be used on electronic devices to provide effective and durable seals against the ingress of moisture and dust, fill gaps, and dampen vibration.
Industrial equipment. Microcellular urethane foam parts can be used in a variety of industrial equipment for gasketing, sealing, cushioning, and impact protection.
Depending upon the specific application and end use. CRG can select different grades of microcellular urethane foam in a variety of formulations and thicknesses. Formulations vary in the rigidity of the material, the closed cell density, and the material thickness. Formulations are available to support applications where the following specific properties are needed:
Higher impact resistance. Formulations with greater material stiffness or rigidity give greater resistance to impacts and shocks.
Low closure force. Extra-soft formulations require lower force to be applied on seals and closures.
Enhanced water resistance. Formulations are available to service applications where enhanced resistance to water is desired.
