On the Road

Tires That Improve Fuel Economy

By lowering the rolling resistance of tires, Kao raises fuel efficiency and reduces carbon dioxide emissions. These tires roll easily, yet they also exhibit outstanding wet-grip and braking performance. The secret? Kao's new silica dispersion improver.

What Gives a Tire Both High Fuel Efficiency and Powerful Grip

How can tires reduce rolling resistance, while improving wet-grip and braking performance? If a tire rolls more easily, then wouldn't a car's braking and handling suffer? The answer is to make tires using silica as a filler, because it also improves grip. But silica doesn't mix well with rubber, so not much could be used. That's why Kao developed a new silica dispersion improver (100% plant-based) in collaboration with Bridgestone. This lets tire makers use much more silica to achieve even better fuel efficiency and wet-grip performance, creating optimized eco-tires.

At Construction Sites

Cement That Helps Keep Water Clean

Many public works projects are constructed in contact with bodies of water. Architectural structures such as harbors and seawalls, bridges and tunnels are essential infrastructure for public safety, convenience and commerce. Kao developed a cement thickener to build durable concrete structures without polluting the water at the site.

Waterside Construction Requires Highly Viscoelastic Concrete and Cement Paste.

Kao's Visco Top raises the viscoelasticity of concrete to prevent washout, while assuring mold-filling injectability and rapid, strong setting. The resulting high fluidity and workability are particularly helpful when building on uneven terrain or in tight places. By minimizing washout of wet concrete into the water, Visco Top also helps keep oceans, lakes, rivers and groundwater clean, an extremely valuable benefit.

In the Office

Energy Saving Toner

Computers, lighting and air conditioners are just a few of the office appliances that consume electric power throughout the business day. Energy saving measures benefit businesses by reducing fixed costs. No wonder so many offices are adopting Kao's low-temperature fixing toner for their laser printing and copying needs.

A Toner That Requires Less heat Saves More Energy.

プリンターの省エネのイメージ図

MFPs (and stand-alone copiers and laser printers) use a finely powdered ink called "toner" to create their images. Typical toner particles are only a hundredth of a millimeter in size. Heat melts the toner, fixing it to the paper. This heat accounts for about 70% of a typical MFP’s energy consumption. Kao's Low-temperature fixing toner melts at only 135℃. Compared to conventional toner, that's more than 30℃ lower. Since 40% less electric power is required for printing, it's hardly surprising that, worldwide, one out of every three toner-printed pages relies on Kao Low-temperature fixing toner or toner binder.

For Paper Recycling

De-inking Agent Conserves Resources

Japan recycles about 80% of the approximately 2.6 million tons of paper the nation uses annually. Newspaper, toilet paper, copier paper and cardboard are often made of recycled paper. Kao's De-inking agent pulls old ink away from recycled pulp so this valuable resource can be transformed into new products.

Detergent Technology Key to Waste Paper Recycling?!

Ordinary paper is made from pulped wood fibers. Recycling of old newspapers and magazines begins with fiberizing the paper in water into pulp again. Then the ink must be removed to make the recycled pulp pure and white. This de-inking process uses tiny bubbles that pull the ink off the pulp fibers. The inky foam floats, leaving behind the pure recycled pulp to be made into useful, valuable raw material of paper. This technological idea comes from the similar principle of ordinary laundry detergent to remove dirt from clothing. Kao's De-inking agent exhibits especially powerful ink removing performance, featuring excellent foam breaking ability of the inky foam. As Kao continues to refine this technology, we can look forward to seeing more paper recycling than ever.
