Difference between poron foam and ordinary foam

Poron foam it is by the United States Rogers Corporation (Rogers Corporation) research and development of a patented product, Poron foam belongs to the microcellular polyurethane foam, its internal structure is made up of a large number of interconnected tiny closed-cell composition. These tiny closed-cell structures give Poron foam excellent resilience and cushioning properties. For example, after being extruded by external forces, Poron foam can quickly return to its original shape, because its internal microcellular structure can effectively disperse the pressure, and after the pressure disappears, the molecular chain inside the foam can quickly rebound.

Comparison of the properties of PORON foam and ordinary foam

Poron Foam

Cushioning performance: Poron foam can absorb and disperse high-energy impact, under the same thickness and pressure conditions, it can provide superior cushioning effect. For example, in the insole application of sports shoes, Poron foam can effectively reduce the impact of the ground on the feet during exercise, to protect the feet and joints.
Resilience: Highly resilient, after many compression and release, still able to maintain good elastic recovery ability. This makes it in need of long-term use and the need to maintain the shape of a stable product performance, such as the internal cushioning of electronic products, long-term pressure by the parts of the equipment, Poron foam can always maintain good elasticity to protect the equipment.
Fatigue resistance: Poron foam can withstand frequent pressure changes without easy damage, can withstand a lot of compression - rebound cycle. This is very important for some products that need to be opened and closed repeatedly, such as electronic devices such as protective cases and other application scenarios.

Ordinary foam

Cushioning performance: the cushioning performance of ordinary foam varies depending on the material and structure, but in general in the absorption of high energy impact is not as good as Poron foam. For example, some ordinary packaging foam, in the event of the impact of heavier items, may not be able to provide sufficient cushioning protection.
Resilience: resilience is generally weak, after many compression may appear deformation can not be recovered. For example, some ordinary foam used for padding may collapse and fail to return to its original state after being compressed for a long period of time.
Fatigue resistance: Compared with Poron foam, ordinary foam fatigue resistance is poor, in the frequent pressure changes are more likely to rupture, loss of elasticity and other issues.

Areas of application of PORON Foam versus regular foam

PORON foam is widely used in the internal cushioning and shock absorption of cell phones, tablets, laptops, cars and other products. For example, in the interior of cell phones, Poron foam can be placed between the battery and the motherboard to prevent the battery and the motherboard from crushing each other when the phone is hit by a collision or fall. It can also be used for cushioning and soundproofing of car seats, dashboards and other components. In car seats, Poron foam can provide a comfortable riding experience, while absorbing the vibration of the vehicle driving process.
Ordinary foam is mainly used for product packaging, play a role in preventing the product in the transportation and storage process by collision and damage. For example, some fragile products are filled with ordinary foam inside the box to isolate and buffer. Or as a wall, furniture and other decorative materials, to provide a certain degree of softness and decorative effect. For example, some soft package furniture using ordinary foam to increase comfort and aesthetics.
