Fluorescent whitening agents, also known as optical brighteners, may be added to coating formulations to increase sheet brightness. Polyvinyl alcohol (PVOH) is recognized worldwide as the most effective “carrier” for optical brighteners.
Fifty years ago, most perishable items such as meat, cheese, or vegetables were packaged in glass or metal containers. Even soda was packaged exclusively in glass containers. Today, many perishable items are packaged in flexible, plastic containers.

Polyvinyl alcohol is widely used textile warp sizing composition. Selvol Polyvinyl Alcohol for textiles is an excellent film former, providing a protective coating for spun and filament yarn. It is coats the textiles with a sturdy film, however, it is easily removed (desized) with hot water. Features of Selvol polyvinyl alcohol as a warp sizing agent include superior:
Because Selvol polyvinyl alcohol is a water-soluble polymer, it is sometimes perceived as having little or no water resistance. However, Selvol polymers can provide both water retention or water resistance depending on the grade selected. Our polymer range includes both hydrophilic and hydrophobic polyvinyl alcohol.
Have you ever put together your own entertainment console or coffee table, gluing those little wooden pegs into pre-drilled holes? Or even built your own chairs or tables from scratch? You were probably using a wood glue that featured Selvol Polyvinyl Alcohol (PVOH) as a key ingredient.
Selvol Premiol is a line of high performance polymers specifically designed for the oilfield industry. The polymers improve fluid loss control, gas migration, reduce friction, and enhance oil recovery, making them valuable additions to cementing, injection, fracturing, and drilling fluids.
Sekisui Specialty Chemicals (SSC) has presented research at the Society of Cosmetic Chemist’s Annual Technology Showcase since the launch of our cosmetic quality polyvinyl alcohol (PVOH), Selvol Ultalux. The annual showcase event, held in New York City at the beginning of December, is an opportunity for formulators and chemists from many countries to share and review the latest advances in personal care.
Paper manufacturers are looking for new end uses for coated or treated paper. One area of progress is food packaging; particularly packaging that provides some level of oil and grease resistance. Selvol polyvinyl alcohol (PVOH) is an extremely hydrophilic polymer, and as a continuous film, exhibits total barrier properties to oil, grease, and most organic solvents.
Polyvinyl alcohol (PVOH) is one of the most commonly used film formers in personal care products. A quick search of the Good Guide database (http://www.goodguide.com/) reveals that over 800 different products contain polyvinyl alcohol including mascaras, concealers, masks and peels, foundation
Selvol Polyvinyl Alcohol is an excellent emulsifying and dispersing agent for a wide variety of materials. In particular, it is one of the most widely used polymers for the colloidal stabilization of vinyl-acetate-based emulsions. Polyvinyl acetate (PVAc) homopolymer and copolymer emulsions
As eco-friendly products rise in popularity, more cultures adopt Western style sanitationware, and biomedicine advances in orthopedic and dental reconstruction, the world demand for traditional and technical ceramics is increasing.
In many regions with colder climates, such as the Upper Midwest of the United States, the growing season for crops is much shorter than in more temperate regions. In such climates, morning frost is common well into May.
Advances in ink jet printing technology have resulted in a new generation of ink jet printers which can print faster at wider paper widths, producing four-color images close to photography quality. Ink jet printing papers must respond to these changes through quick ink absorption, minimizing ink bleed and ink wicking while retaining favorable ink optical density values.
Selvol polyvinyl alcohol is used as a primary and ancillary adhesive binder in many household items. From the envelopes we seal our letters into, the wood furniture we assemble, and the books we read, there is Selvol polyvinyl alcohol in all of these.
Polyvinyl alcohol is widely used textile warp sizing composition. Selvol Polyvinyl Alcohol for Textile Warp Sizing is an excellent film former, providing a protective coating for spun and filament yarn. It’s tough film, however, is easily removed (desized) with hot water.
