Waterproof sealing of electronic devices

Electronic devices are often prone to contact with sweat in daily use, and in the event of an accident will encounter tea. These situations are increasingly stringent requirements for the waterproof sealing of electronic devices. It has become a challenge for engineers to design and produce foam materials that are waterproof.

Rogers waterproof sealing foam series uses water-repellent raw materials added to polyurethane to produce polyurethane foam that meets the material's compressibility and good thickness retention properties while providing excellent waterproof sealing effects. It can help with the waterproofing problem of electronic equipment.

Advantages and applications of foam materials in electronic equipment

Advantage：

Flexible and easy to compress
Excellent waterproof seal
Good sealing effect
Excellent durability
Vibration and noise reduction

Features:

Abundant thickness, 0.10~4.00mm thickness provides options for various spaces that need to be filled
Good sealing, under the right amount of compression, can provide a good dust-sealing effect for equipment
Long-lasting elasticity, providing long-lasting and stable positioning for parts that need to be fixed
Super soft and compressible up to 90% compression
Tough surface, easy to match with protective film, not easy to drop
Good shock absorption performance, can effectively protect the components and reduce the impact damage
Excellent resistance to compression deformation, providing long-lasting protection for equipment

Application areas:

Polyurethane foam is widely used for cushioning in cell phones and laptops, electronic devices, as well as in the interiors of aerospace and rail vehicles. Urethane foam has excellent resilience, good vibration and impact absorption, and an excellent waterproof sealing effect. Its wide range of hardness and thickness options and ease of compression makes it suitable for applications requiring high flexibility.

Applications Scope:

Cell phone speakers, power modules, lampshade sealing, automotive, electronic equipment, and computer communication equipment industries

Electronics, cameras, speakers, LCDs, signage, etc. fixed bonding and protection

Battery, plug compression foam

Computer, and electronic equipment, such as foot pads
