CHEMIPEARL™, which is made of fine particles of polyolefin, uses Mitsui Chemicals’ unique technology and is an environment-friendly aqueous dispersion that does not use emulsifying agents or organic solvents (except for some grades and Products in Development).
Abrasion resistant Improved slip properties Anti-blocking agent Superior application properties Outstanding heat-sealing properties Hygienic qualities
Additives for printing ink, heat sealants
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.
Efficient aqueous dispersion polyolefin that does not require emulsifying agents or organic solvents.
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™
Can be applied to paper, aluminum, films, etc. by spray or gravure coating. (A, M, V, S types)
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)
Polyolefin material with superior hygienic qualities, enabling its use in food packaging. (M, V, S types)
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.
