Anti-blocking and Heat Sealing Agent CHEMIPEARL™

CHEMIPEARL™ is a particulate aqueous dispersion made of fine particles of polyolefins, previously considered 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 with good waterproof ability. The water based additive is used in a variety of applications as a heat-sealing and anti-blocking agent. CHEMIPEARL consists of spherical particles with narrow particle size distribution and exhibits excellent rub-off resistance, and heat sealing, slip and anti-blocking properties.
