SWP™ / KEMIBESTO™ is a 100% fibrillated polyolefin fiber with good hydrophilicity, superior smoothness, high whiteness, exceptional heat sealability, and outstanding moisture resistance. By integrating SWP™ high-performance fiber with paper and nonwoven fabrics or compounding it with cement and coating materials, new characteristics and new functions become possible. The unique functionality and characteristics of SWP™ bring revolutionary ideas and innovations to a wide range of industries from food and pharmaceutical packaging, paper products, coating materials, paints and building materials, industrial materials, to beauty and healthcare.

KEMIBESTO™ is a dried and fluffed polyolefin synthetic pulp (SWP™ ) with fibrillated fibers that disperse readily in water or organic solvents bolstering particle retention and viscosity controllability as well as other valuable characteristics important in a wide range of applications including but not limited to paints, coatings, and adhesives.


Heat sealability

SWP affords heat sealing properties that express adhesion, and is used for food packaging such as tea bags.

Chemical resistance/Heat fusionability

SWP has superb thermal adhesion properties, mouldability, shape retention and chemical resistance to acid and alkali, and is used for various industrial products.


SWP synthetic paper's highly-fibrillated fiber (multi-branched, high surface area, controlled freeness) has excellent cement particle entrapment, mouldability and thixotropy and is used for roofing tiles, coatings and adhesives.


SWP-blended paper has fine embossibility and enhances three dimensional and transparent designs compared with conventional paper.

Surface smoothness

Calendared paper has a highly smooth surface for enhanced printability. A coating to its surface is added for use for labels, posters and other printed products.
