Advanced Functional Film
Clean Energy Materials
These films diffuse the luminance coming from light.
They use energy efficiently, enhance brightness, and create beautiful screens without luminance unevenness.
This product accounts for a high share in the world by combining high brightness and high diffusion at a high level. In the future, this product will be widely used for sensors, further expanding Keiwa's market areas.
【Applications】Used for liquid-crystal displays and sensors in such devices as smartphones, tablets, laptops, in-vehicle monitors, etc.
Advanced Functional Film
These films lowly control retardation and prevent interference patterns.
We provide clear films and matte films by controlling film surface shapes to match customers' needs and functions.
The product range is created not only from polycarbonate but also from a variety of plastic resins with heat resistance and processability features. Films and sheets are used not only in the optical systems, such as display surface protection, but also in many other fields.
【Applications】Smartphones, in-vehicle products, business-used monitors, sensors, display surface protection, etc.
These separators are used in the process of creating carbon fiber prepreg and synthetic leather, such as urethane sheets and PVC sheets.
For example, they serve as mats only used during molding, like cooking sheets for making cookies.
The "separator" is a registered trademark of Keiwa.
This is a type of process papers used as mats when foaming the urethane materials of sponges, low-rebound pillows, etc.
With loss reduction and environment beautification features, it is a top-share product.
【Applications】Process papers used for foaming urethane
These processing papers are used for sheeting with urethane and PVC.
We provide the appropriate ones for each material and surface shape. They are repeatedly used because of their durability and releasability.
【Applications】Urethane, PVC, and synthetic leather-used processing papers
These processing papers are used in making carbon prepreg. They are produced with consideration of the affinity and releasability of epoxy resin and the emphasis on dimension stability.
【Applications】processing papers used for carbon prepreg (carbon fiber prepreg)
Packaging papers protect product quality from moisture, water, and rust. We also provide recyclable types that prevent paper products from absorbing moisture in the air, dimensional changes, and curling. Corrision inhibiting paper protects metal products from rust by using a vapor phase corrosion inhibitor.
Moisture-proof and Waterproof Paper
This type of moisture-proof paper protects water-vulnerable objects like papermaking to laminate polyethylene on paper and is also used as a filling agent of silicone-coated paper like separators. "Tokay Barrier" is a product that features the disaggregation property and recyclability, such as recycled papers.
【Applications】Filling materials such as release papers for papermaking/ ferrous moisture-proof and waterproof
Corrosion Inhibiting Paper and Corrosion Inhibiting Film – K-Light Series
Corrosion inhibiting papers help to protect ferrous and non-ferrous metals from rust. In addition to that, there are types of laminating polyethylene that enhance the moisture-proof and lengthen the corrision inhibiting time. Even more choices of laminating resin cloths, etc, are available for requirements of additional strength.
【Applications】Used for ferrous, non-ferrous, and common corrosion inhibiting packaging
Clean Energy Materials
We provide new clean energy-related materials, such as solar cells, secondary cells, wind power generators, etc.
We aim to manufacture products using natural energy, such as durable and high-barrier sheets that protect products from time-related deterioration.
Backsheet for PV modules
The backsheet (Appli-Sola) is one of the components that forms the solar cell module and is used for maintaining performance by fixing and protecting internal cells such as moisture-proof, insulation, weather-resistance, and high adhesion to the encapsulant.
【Applications】Backsheets for solar cells
Reflective sheets and gutter sheets support the growth of crops.
These sheets can significantly make use of various climate and weather conditions, which is essential to the agriculture field and greatly enhances efficiency.
This product is manufactured to replace galvanized iron that is used in the gutters of conventional multi-span greenhouses and features enhanced work efficiency, weight saving, and life extension characteristics.
【Applications】Used for rain gutters in multi-span greenhouses
This waterproof sheet is used for covering the greenhouse foot. It features weather resistance and heat-keeping effects for greenhouses. It also helps houses away from insects.
【Applications】Cover the foot of installed gardening houses
By spreading the product on the ground, customers can constantly maintain the temperature and humidity in the soil and promote the germination of crops. Due to the high reflection, it has a repellent effect against pests and harmful animals.
【Applications】Cover ridges on which crops are growing, surround greenhouses (an anti-insect measure), etc.
Pasting the product inside established greenhouses helps to save energy and has an excellent heat-keeping effect.
【Applications】Indoor heat keeping (greenhouses, livestock barns, hen houses, etc.)
This product promotes excellent cool-keeping effect when pasted outside an established greenhouse.
【Applications】Heat-keeping, cool-keeping coating materials (greenhouses, livestock barns, hen houses, etc.)
This product promotes the growth of fruit and the like by reflecting sunlight.
【Applications】Reflective sheets for cherries, apples, oranges, etc.
