What industrial fields are Rogers foam generally used after processing?
Rogers foam, as a representative of high-performance polymer foam materials, is widely used in industrial fields with strict requirements on material properties after processing because of its excellent core characteristics such as cushioning and shock absorption, sealing and heat insulation, electromagnetic shielding, high and low temperature resistance, and compression set resistance. The following is a detailed classification of its main application scenarios:
I. Electronic, Electrical and Consumer Electronics
This field is one of the core application scenarios of Rogers foam, especially to meet the requirements of protection, heat dissipation and performance optimization of precision electronic components. Common processing forms include customized gaskets, buffer pads, sealing strips and shielding foam components.
Consumer electronic terminals: used for smart phones, notebook computers, tablet computers, smart watches and other devices. For example, in mobile phones, processed Rogers foam (such as PORON® series) can be used as a buffer pad between the screen and the middle frame to absorb the drop impact to protect the screen; As a sealing gasket around the battery, it can isolate dust and water vapor, and at the same time buffer the slight deformation caused by battery heating; Under the keyboard of notebook computer, it can be processed into a mute cushion to reduce the noise and wear of keystroke.
Electronic components and modules: adapt to chips, sensors, connectors and other precision components. For example, in the RF module of 5G base station, Rogers foam can be processed into electromagnetic shielding foam (composite conductive layer) to block electromagnetic interference (EMI) and ensure the stability of signal transmission; On the PCB circuit board of automobile electronics, it can be used as a heat dissipation buffer pad to fill the gap between components and the heat dissipation shell, improve the heat dissipation efficiency and avoid the damage of components caused by hard contact.
New energy electronics: In the charging pile and energy storage battery pack, it is processed into high-temperature and aging-resistant sealing gasket and buffer pad to isolate external moisture and dust, and at the same time absorb the vibration during the operation of the battery pack and protect the internal batteries and circuits.
Second, the automotive industry
The automobile industry requires high and low temperature resistance (-40℃~150℃), oil resistance, aging resistance and environmental protection (meeting VOC and ELV standards) of foam. Rogers foam (such as BISCO® and PORON® series) can cover many modules such as power system, interior, chassis and electronic control after processing.
Automobile interior and comfort: processed into door sealing strip, dashboard cushion gasket, seat noise reduction gasket, etc. For example, the foam seal at the door frame can fill the gap, improve the sound insulation effect (reduce wind noise and road noise), and enhance the "heavy feeling" when the door is closed; The cushioning foam under the seat can absorb the bumping vibration and improve the ride comfort.
Power and transmission system: used for high-temperature sealing and damping parts around engine compartment and gearbox. For example, the sealing gasket connected between the engine block and the pipeline should be resistant to engine oil corrosion and high temperature, and the chemical resistance and temperature resistance of Rogers foam can meet the requirements; At the joint between the motor and the frame, it is processed into a damping bushing to reduce the vibration transmission when the motor is running and protect the frame and other components.
Automotive electronics and new energy vehicles: in the battery pack of new energy vehicles, it is processed as a buffer layer between batteries to absorb collision impact and at the same time have a certain heat insulation effect to prevent the battery cells from spreading out of control; In the case of vehicle-mounted radar (such as millimeter-wave radar), as a sealing and buffering component, it protects the radar module from external environment interference and ensures the detection accuracy.
Iii. Industrial equipment and machinery manufacturing field
Industrial equipment (such as machine tools, automatic production lines, heavy machinery) has outstanding requirements on compression permanent deformation resistance, wear resistance and mechanical impact resistance of foam. After processing, Rogers foam is mostly applied in the form of shock absorber, seal and anti-skid pad.
Shock absorption and protection: between the base of the machine tool and the ground, it is processed into a high-hardness cushion to absorb the vibration of the machine tool during operation, reduce the damage to the ground, and improve the machining accuracy of the machine tool (to avoid workpiece errors caused by vibration); At the end of the mechanical arm of the automatic production line, it can be processed into a flexible cushion to prevent the workpiece from being damaged due to excessive force when grasping the workpiece, and at the same time increase the grasping friction.
Sealing and dustproof: at the door of industrial oven and high-temperature equipment, it is processed into a high-temperature sealing strip to isolate the high temperature in the box from the cold air outside, improve the heating efficiency of the equipment, and prevent the waste of energy caused by heat leakage; In outdoor mechanical equipment (such as engineering machinery cab), it is used as a door and window seal to block rain and dust from entering and protect internal circuits and operating components.
Anti-skid and cushioning: the surface of the pedal of heavy machinery (such as forklift and excavator pedal) is processed into an anti-skid foam pad to increase the friction between the operator's foot and the pedal and avoid the potential safety hazard in wet and slippery environment; In the transportation packaging of equipment, it is used as a customized lining to fix the equipment parts, absorb the bump impact during transportation and prevent the parts from collision and damage.
Fourth, the field of medical equipment
Medical equipment requires strict biocompatibility (non-toxic, non-irritating), disinfection resistance (alcohol tolerance, high temperature sterilization) and cleanliness of materials. Rogers foam (such as medical-grade PORON®) can be used for medical instrument casings, consumables and patient contact parts after processing.
Sealing and buffering of medical instruments: sealing gaskets are processed at the gaps in the shells of ultrasonic diagnostic instruments and blood analyzers to prevent dust and liquid from invading, ensure the cleanliness of the internal circuits of the instruments, and reduce the noise when the instruments are running; At the adjusting knob of the surgical microscope, it is used as a damping cushion, which makes the knob adjustment more stable and improves the doctor's operation accuracy.
Contact parts for patients: The supporting parts of wheelchair cushions and rehabilitation equipment are processed into flexible cushions to improve the comfort of patients when using, and at the same time, they are breathable and clean-resistant, which is convenient for daily disinfection; In the probe fixing belt of medical monitor, the foam pad is embedded to reduce the pressure of the probe on the patient's skin and enhance the fixing stability.
Medical consumables assistance: it is used as a sealing component in some connection parts of disposable infusion set to prevent liquid medicine from leaking; Soft foam pads are processed at the headrest and armrest of the dental chair to improve the comfort of patients during treatment and relieve tension.
V. Aerospace and Rail Transit
In this field, materials are required to be lightweight, resistant to extreme environment (high and low temperature, high altitude and strong radiation) and fatigue resistance. Rogers foam is mostly used for equipment sealing, shock absorption and heat insulation after processing.
Aerospace equipment: between the dashboard and the shell of the aircraft cockpit, it is processed as a sealing gasket to isolate the influence of low temperature and air pressure change on internal instruments; In the electronic cabin of a satellite or spacecraft, it can be used as a thermal insulation buffer component to reduce the interference of external temperature difference on components, absorb the vibration during launch and on-orbit operation, and protect precision equipment.
Rail transit (high-speed rail, subway): in the sealing groove of the high-speed rail door, it is processed into elastic sealing strip, which needs to withstand the strong wind and air pressure impact when the high-speed rail runs at high speed, and has good sound insulation effect (reducing noise transmission inside and outside the carriage); Under the floor of the subway car, it is used as a damping pad to absorb the vibration caused by the friction between the track and the wheel, and improve the comfort of passengers. In the signal equipment of rail transit (such as track circuit module), as a sealing and buffering component, it protects the equipment from rain, dust and vibration and ensures the stability of signal transmission.
