What are the benefits of Rogers PORON 4790-92 series foam?

Physical properties

• Excellent resistance to compression deformation: can maintain stable sealing and cushioning performance after a long period of compression, for example, in electronic products, long-term use can continue to effectively protect precision components, to prevent the loss of cushioning effect due to the deformation of the foam.
• Good resilience: soft and slow rebound characteristics, can slowly return to its original shape after pressure, can maintain stable performance for a long time, after repeated use can still provide reliable cushioning and protection, applicable to the need for frequent opening and closing or moving parts, such as laptop computers, the pivot part.
• Thickness and dimensional stability: PET one-piece molding, the product thickness is uniform, under high pressure, high deformation conditions still have excellent spatial stability, to ensure that in different use of the environment and pressure, can be accurately adapted to play a role in, such as in the narrow internal space of the electronic equipment, the stability of the thickness and dimensions of the components to ensure the close installation and normal operation.

Chemical properties

• Low gas release and non-atomization: In the process of use will not release a large amount of gas or atomization phenomenon, to avoid pollution or impact on the surrounding environment and other components, can ensure the cleanliness and normal operation of the equipment inside, commonly used in precision electronic equipment with high environmental requirements 1.
• Does not contain polluting chemicals: does not contain harmful substances, such as plasticizers, etc., will not cause pollution and harm to the equipment and the human body, in line with environmental protection requirements, safer and more reliable to use, can be widely used in various types of contact with the human body or strict environmental requirements of the product 12.
• Good flame retardancy: most of the materials meet the flame retardancy requirements of UL94 HBF and MVSS 302, no need to add additional flame retardants, the material itself has flame retardant properties, which can effectively reduce the risk of fire and improve product safety, applicable to electronic and electrical appliances, automotive and other products with fire protection requirements1

Processing and use

• Easy to process: clean die cutting, can be used with a variety of adhesives, can be easily processed and molded according to different design requirements, improve production efficiency, reduce processing costs, can meet a variety of complex shapes and sizes of custom requirements, widely used in the manufacture of different products.
• Good surface wettability: excellent surface wettability, easy to bond, easy to combine with other parts firmly, to ensure that in the process of use will not fall off or shift, to ensure the overall stability and reliability of the product.
• Strong temperature adaptability: can be used in the temperature range of - 40 ℃ to 90 ℃, can adapt to different working environment temperature, in low and high temperature conditions can still maintain good performance, can be used in a variety of harsh environments under the protection of equipment, such as outdoor electronic equipment, automotive engine compartment and other parts.

Wide modulus range: The specially designed polyurethane formulation provides a wide range of modulus for a variety of design requirements. It can meet the hardness and elasticity requirements of different products, providing greater flexibility for product design, and allowing for the selection of the appropriate modulus for customization according to specific application scenarios and component requirements.
