BASIC INFORMATION

CHEMIPEARL™ is a particulate aqueous dispersion developed by Mitsui Chemicals, Inc. It is a unique product made of fine particles of polyolefins, previously considered 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 environment-friendly. Characteristics of polyolefins, such as mechanical, water-resistant, and chemical resistant properties, are retained intact, making the product ideal for widespread use as printing ink additives, heat sealing for food packaging, adhesives and binders, and anti-blocking agents.

CHARACTERISTICS

Aqueous Dispersion

Efficient aqueous dispersion polyolefin which does not require emulsifying agents or organic solvents.

Abrasion Resistant

Spherical particles with narrow particle size distribution resistant to abrasion with excellent slip and anti-blocking properties. (A, M, V, W types)

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 which provides superior hygienic qualities enabling its use in food packaging. (M, V, S types)

APPLICATIONS

Heat sealing agent, additive in coating agents, printing inks

Abrasion resistant characteristics of CHEMIPEARL™

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.
