CHEMIPEARL™

Polyolefin-based Aqueous Dispersion

CHEMIPEARL™ is made of fine particles of polyolefin. It uses Mitsui Chemicals’ unique technology and is an environment-friendly aqueous dispersion, which does not use emulsifying agents or organic solvents (except for some grades and products being in development).

It is abrasion resistant, has improved slip properties, is an anti-blocking agent, has superior application properties as well as outstanding heat-sealing properties and hygienic qualities.

BASIC INFORMATION

CHEMIPEARL™ is a particulate aqueous dispersion developed by Mitsui Chemicals Inc. It is an 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 and chemical resistant properties are retained intact and make 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, 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)

Magnification of CHEMIPEARL™ 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 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)

Additives for 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.
