BISCO HT-1270 Applications

  • Active Safety

    Innovative material solutions enabling reliability of Advanced Driver Assistance Systems and autonomous vehicles.

Automotive safety systems designed to avoid accidents are becoming increasingly common in today’s vehicles. New cars are often equipped with robust collision avoidance technologies due to regulations mandating their inclusion. These Active Safety technologies are enabled by innovative Advanced Driver Assistance Systems (ADAS) and use several sensor technologies, including radar, to detect conditions that may lead to a collision. With this, ADAS helps drivers arrive safely at their destination. Rogers is the world’s technology and market leader in innovative material solutions, providing high performance printed circuit board (PCB) laminates for automotive 24 GHz and 77 GHz radar sensor applications enabling active safety.

Advanced Driver Assistance Systems (ADAS)

Radar-based ADAS systems are active safety systems that assist drivers by giving vehicles the virtual ability to sense the static and dynamic objects on the road. High frequency circuit materials from Rogers Corporation are critical to the reliability of radar sensors essential for ADAS. At RF and millimeter wave frequencies such as 24 and 77 GHz, radar sensor designers require thin core PCB laminates with low insertion loss and low dielectric constant. Rogers’ materials have an established reputation for excellent quality and reliability in the electrical and mechanical properties required for radar sensors to achieve the highest performance.

  • 76-81 GHz Radar Sensors - Driver assistance functions, like forward collision warning, emergency brake assist, adaptive cruise control and traffic jam pilot, require radar sensors operating in a range from 76-81 GHz. RO3003G2™ high-frequency laminates provide outstanding dielectric constant stability and the lowest insertion loss. For very cost-sensitive designs, RO4830™ laminates provide good electrical performance and lower total PCB fabrication cost. For designs which include multiple RF layers, CLTE-MW™ laminates provide a woven-glass reinforced sister product to RO3003G2, which is also compatible with SpeedWave® 300P Prepeg and RO4450T™ bond ply options.
  • 24 GHz Radar Sensors - RO4835™ high-frequency circuit materials are commonly used in 24 GHz radar sensors for blind spot detection or rear cross traffic alert. In blind spot detection, radar sensors continuously monitor the presence, direction and speed of vehicles in adjacent lanes and alert the driver of any danger. RO4835 materials have proven their high-frequency capabilities and offer the circuit fabricator a process that is more aligned to standard PCB materials.

Autonomous Driving Sensors

Sensors play a key role in advanced driver assistance systems and autonomous vehicles. They act as the eyes and ears of a vehicle and have quickly become indispensable components in ADAS and autonomous driving vehicles. Rogers Corporation offers a comprehensive portfolio of material solutions that solve sensor sealing and vibration design challenges.

  • PORON® polyurethane and BISCO® silicone materials offer great compression set resistance, ensuring a tight seal is maintained throughout the life of the vehicle.
  • BISCO® silicones exhibit excellent sealing performance with providing resistance to UV, ozone and extreme temperatures.
  • PORON® polyurethanes deliver reliable vibration dampening for sensor units, as well as noise reduction.

Gasketing and Sealing

Reliable gaskets and seals must withstand challenging conditions and industry standards.

For successful sealing in enclosure and gasket design, material selection is critical. A gasket’s primary task is to protect components and prevent failures and unplanned maintenance. Compressibility, environmental exposure, sealing effectiveness and specifications should be considered when selecting a material for gasket seal design. Effective sealing and gasketing materials must be able to withstand the effects of compression, manage damaging impact energy and seal out dust and particulate matter. Rogers offers a portfolio of high performance sealing and gasketing solutions that are highly compressible and conformable while resisting compression and stress relaxation. These unique materials effectively seal out dust, water and other contaminates for the life of the product.

Sealing Effectiveness and Compressibility

Assembled housings or enclosures must ensure adequate gasket compression to provide the required level of seal. This compressibility enables the load to remain within required limits while accommodating a larger range of compressions. The seal or gasket needs to conform specifically to its surfaces, whether an aircraft, automobile or industrial enclosure. If the gasket leaks requires replacement, enclosure certification can be lost, resulting in lost time and increased expenses in addition to the damage incurred to the components. PORON® Polyurethane and BISCO® Silicone foams are highly compressible and conformable, effectively sealing for the life of the product. Both are available in a wide range of firmness and thickness options to ensure robust sealing design.

Long-Term Sealing Durability

A significant factor in long-term sealing durability is the ability of the material to resist compression over time. Choosing materials with excellent Compression set (C-Set) retention helps keep a consistent closure force on a door or panel, creating a more durable seal. C-Set resistance is the ability of an elastomer to return to its original thickness after a compression load, under a specified time and temperature, is released. If a gasket takes a significant C-Set, sealing may be compromised due to the decreased thickness. This loss of thickness normally takes place over time and is not always evident during initial testing. PORON® polyurethane, BISCO® silicone and Griswold® cellular rubber materials provide excellent resistance to compression set, exhibiting excellent physical properties and sealing characteristics for the life of the product.

Environmental Considerations

Addressing environmental considerations -- outgassing, chemical and solvent resistance, temperature load, flammability and sealing standards -- can be a challenge when creating a successful seal or gasket. Both PORON® Polyurethanes and BISCO® Silicone foams are low-outgassing, non-fogging and contain no plasticizers or residual chemicals to contaminate devices. The materials will not become brittle and crumble and are non-corrosive to metal.

Meeting Industry Standards

Aircraft Specifications - Aircraft are subject to some of the most stringent specifications in the transportation industry. All seals must meet Federal Aviation Regulations (FAR) flammability. BISCO® silicones reliably meet various FAR specifications and are specified to many OEM material specifications including Boeing and Airbus. Rogers is AS9100 certified and has been awarded multiple Boeing supplier Performance Excellence Awards.

Automotive –PORON® Urethanes and BISCO® Silicones are certified for use under several standards, including UL-508 (industrial control equipment), UL-1572 (HID lighting fixtures) and especially UL-50E (electrical enclosures), with testing done to the new periodic recompression standard. PORON cellular urethane products also meet environmental standards’ requirements for UL 50E electrical equipment, UL 508 industrial control equipment and UL JMST2 gasketing.

Enclosures Specifications - Seals must be resistant to temperature extremes and meet industry regulations.

Rogers’ specialty materials meet or exceed automotive specifications for flame resistance (FMVSS302), fogging (SAE-J 1756), Ford WSS-M2D496, Ford WSL-M99G163, General Motors GMW14196, General Motors GMW16392, Chrysler MS-AY549 and Chrysler MS-AY-556.

 

Flammability & Sealing Standards - Rail cars are subject to very stringent specifications that are enforced by many national governing bodies of rail. Components used within the railcar must meet specific Flame, Smoke and Toxicity requirements depending on its usage and location. BISCO® silicones meet various national rail standards including NFPA 130 (US), BS 6853 (UK), DIN 5510 (Germany), EN 45545 (Europe) and NFF 16-101 (France).Rail Fire Safety Standards - Many PORON Urethane foams meet the flammability requirements of UL HBF and MVSS 302. In addition, PORON cellular urethane products meet environmental standards such as UL JMST2 gasketing, AMS 3568 Corrosion Resistance and ASTM G53 UV Resistance requirements.
