ISOKING™ Building Waterproof Breathable Membrane Material, Energy-Saving

Waterproof and Breathable Membrane-Direct Supply from Professional Manufacturer

1. Solving the Industry Pain Point of "Waterproofing and Breathability

As a high-tech polymer composite material, the core value of the waterproof and breathable membrane is to achieve two-way protection of "liquid water barrier + gaseous water permeability", breaking the limitation of traditional waterproof materials that are "airtight", and fundamentally solving the damage problems of various products and structures caused by moisture, condensation and air pressure imbalance. Its core functions are mainly reflected in three dimensions:

Efficient Waterproof and Dustproof, Building a Solid Protection Barrier

Through precise microporous structure design, the pore diameter of the product is controlled between 0.1~0.2 microns, which is much smaller than the diameter of liquid water droplets (about 200 microns). It can effectively block the intrusion of rainwater, sewage, seawater, oil stains, dust, particles, and other pollutants. The waterproof grade can reach IP64-IP68, and the dustproof grade can reach above grade 6, providing comprehensive protection for internal components and substrates, avoiding corrosion, short circuit, aging and other problems, and extending the service life of products. At the same time, the surface of the membrane has excellent hydrophobicity and oleophobicity, which is not easy to be wetted by liquids, and can adapt to complex and harsh service environments.

Rapid Ventilation and Moisture Removal, Balancing Internal and External Air Pressure

The pore diameter of the membrane is much larger than the diameter of gaseous water molecules (about 0.004 microns), which can realize the free penetration of gaseous water molecules, quickly discharge water vapor and moisture in the closed space, avoid condensation, and keep the internal environment dry. At the same time, it can balance the air pressure difference between the inside and outside of the closed structure, reduce the stress damage of seals, and reduce problems such as shell deformation and seal failure. It is especially suitable for scenarios with high requirements on internal dryness and air pressure stability, such as electronic equipment and closed containers.

Weather and Wear Resistance, Adapting to Complex Working Conditions

Using high-quality polymer raw materials and advanced production processes, the product has excellent resistance to extreme temperatures, ultraviolet rays, salt spray, and chemical corrosion. It can work stably for a long time in the temperature range of -180℃ to +250℃, and there is no obvious performance attenuation after 1000 hours of salt spray test and 500 hours of UV aging test. At the same time, the membrane has high mechanical strength, is not easy to age and crack, and can adapt to various complex working conditions such as outdoor, underground, and chemical industry, without frequent replacement and maintenance, reducing the later operation and maintenance costs of customers.

2. Core Applications of Waterproof and Breathable Membranes: Covering B-end Application Scenarios in Multiple Industries

Relying on the core performance advantages of the products, our waterproof and breathable membranes are widely used in various B-end fields such as electronics, construction, new energy, outdoor equipment, and chemical packaging, providing customized adaptation solutions for customers in different industries. The specific application scenarios are as follows:

Electronic and Electrical Field

It is mainly used for the shell protection of outdoor electronic equipment, industrial sensors, smart wearable devices, power tools, and other products, including telecommunication tower equipment, solar photovoltaic modules, surveillance cameras, temperature and humidity sensors, smart watches, electric toothbrushes, etc. It can effectively block the intrusion of rainwater, sweat, and dust, prevent short circuits and condensation fog of internal circuit boards, and at the same time discharge moisture and heat generated during the operation of the equipment, ensuring the stable operation of electronic components and improving the reliability and service life of products. For example, in VOCs sensors used for industrial waste gas detection, the membrane can be used as a "filter window" to block condensed water and particles, while allowing the gas to be measured to penetrate quickly to ensure detection accuracy.

Construction and Building Materials Field

As a key supporting material for the building envelope system, it is widely used in scenarios such as roofs, walls, subways, tunnels, coastal commercial buildings, and logistics and warehousing centers. Its core function is to discharge water vapor inside the building, avoid wall condensation and roof leakage, and at the same time block the intrusion of external rainwater and salt spray, protect the reinforced concrete structure and insulation layer, extend the service life of the building, and reduce the later maintenance costs. According to the needs of different scenarios, we can provide membranes with spunbond, meltblown, and three-layer composite processes, which are suitable for the needs of different projects such as ordinary civil residential buildings, large public buildings and underground transportation infrastructure. Some products have passed green building material certification and fire protection grade B1 certification, meeting the acceptance standards of high-end construction projects.

New Energy Field

Focusing on the new energy vehicle and photovoltaic industries, it is applied to new energy vehicle battery packs, charging piles, photovoltaic inverters, photovoltaic modules, and other products. It can realize waterproof, dustproof, ventilation and moisture removal of the battery pack, avoid the risk of thermal runaway caused by moisture accumulation during battery operation, and at the same time balance the internal and external air pressure of the battery pack to extend the service life of the battery; in photovoltaic modules, it can prevent the intrusion of rainwater and dew, discharge moisture inside the modules, ensure photovoltaic conversion efficiency, and adapt to the harsh environment of long-term outdoor use.
