Viscopearl

Spherical cellulose beads derived from wood pulp
Expected as alternatives to micro plastics

Biodegradable spherical cellulose beads

• - Cellulose beads made from wood-derived pulp

• - Stable to heat and chemicals, and applicable to wide range of purposes (particle size:3μm〜4mm)

• - Spherical and smooth feeling, and high water and oil absorption

• - Soil and marine biodegradable, expected as alternatives to micro plastics

Features of Viscopearl

• - Hard to deform even at high temperatures as decomposition temperature is about 250℃.
• - Resistant to chemicals and stable even against organic solvents.
• - Capable of supporting a wide range of pH values and can be used under various conditions.
• - Smooth texture as it is a spherical bead and does not easily lower fluidity when used as an additive.
• - High affinity for both water and oil, and disperses especially well in water.

PRODUCT LINEUP

● Porous structure ：300μｍ to ４ｍｍ
● Non-porous structure：3μｍ to 200μｍ

Applications

Viscopearl™ can be used as a carrier for aromatic agents or functional chemicals, raw material for cosmetics, or abrasive. It can also be used as a resin or rubber additive by using features of cellulose such as water absorbency. In addition, beads with particle sizes from 3μm to 10μm have a light diffusing effect, allowing them to be used as ink matting agents and light diffusing agents.

Another lineup Viscopearl P

• These are beads manufactured mechanically with wood pulp fiber as the main raw material. The inside of the bead is a continuous hole structure and the diameter of the pores is approximately 10μm. Besides use as a carrier for liquids, it can also be made a bead conjugated with powders such as activated carbon.

  Features of Viscopearl P
  ・has a continuous hole structure
  ・the diameter of the pores is approximately 10μm
  ・Adjustable particle size: 2〜8㎜
  ・can be used as a carrier of liquids
  ・can be conjugated with functional powders → make it easier to handle powdery materials. ※NOT biodegradability because of the binder

  Conjugation technology
  It is possible to create compound beads by mixing with powders during the manufacturing process of Viscopearl P. By conjugating small particles with Viscopearl P, it makes handling easier without impairing functions as a powder. Conjugated with activated carbon
