BASIC INFORMATION
CHEMIPEARL? is a particulate aqueous dispersion developed by Mitsui Chemicals, Inc. It is a unique product made of fine particles of polyolefins, which were previously considered to be extremely difficult to disperse in water. When compared with widely used aqueous dispersion techniques, CHEMIPEARL? is unique in that it does not use emulsifying agents or organic solvents, making it highly environmentally friendly. The characteristics of polyolefins, such as its mechanical, water-resistant, and chemical resistant properties, remain intact, making the product ideal for widespread use as printing ink additives, heat sealing for food packaging, adhesives and binders, and anti-blocking agents.
Aqueous Dispersion
Efficient aqueous dispersion polyolefin that does not require emulsifying agents or organic solvents.
Abrasion Resistant
Spherical particles with a narrow particle size distribution, resistant to abrasions with excellent slip and anti-blocking properties. (A, M, V, W types)
Magnification of CHEMIPEARL?
Superior Application Properties
Can be applied to paper, aluminum, films, etc. by spray or gravure coating. (A, M, V, S types)
Heat Sealing Properties
Offers polyolefin’s excellent mechanical, water-resistant and chemical-resistant properties. When baked after application, it becomes a non-directional, odorless film with outstanding heat-sealing properties. (A, M, V, S types)
Hygienic Qualities
Polyolefin material with superior hygienic qualities, enabling its use in food packaging. (M, V, S types)

Additives for Printing Inks
1.Particles project above the surface of the ink.
2.In the rub-off test,particles are spread on the surface of the ink.
3.Soft wax dispersion has excellent rub-off resistance *1,but gives low slide angle.
