The use of pigment concentrates for in-plant coloration of polymers has become an essential part of plastics technology.
JMB "Dypol" pigment dispersions are manufactured using a unique patented method of production : incorporating pigment into a wax carrier and thereby providing a dust-free method of coloring plastics. The process allows high loadings of pigments into quality waxes which are polymer-specific and approved under EC food-contact regulations.
Dypol dispersions are normally formulated to give a product which can be used for the pigmentation of a number of related polymers at addition rates often as low as 1%.
These dispersions offer both internal and external lubrication, resulting in improved melt flow and mould-release characteristics and giving a better surface finish to the final product. The product facilitates much quicker purge and clean-down times and offers exceptional color dispersion.
Dypol dispersions, which can be used to pigment engineering and other polymers which are normally difficult to color, are already used successfully in the blow-moulding, injection moulding, blown film and extrusion compounding industries.
To summarize, Dypol dispersions offer the following advantages :-
