Clariant wax used in masterbatch Licocene wax vs. plastic

Wax Licocene Plastic

- low molecular weight

- low modulus of elasticity

- mostly high crystalline

- low melt viscosity

- brittle

- low stability of form

by room temperature

- high molecular weight

- medium modulus of elasticity

- low to semi-crystalline

- high melt viscosity

- ductile

- stability of form during

heating

Ceridust and Licocene

- new products - meet your demands

Present demands of the plastics industry are:

increased demand for color

less masterbatch dosage

reduction in number of extrusions

requirements changed to

more economical processing due to high energy and material costs

high quality and best cost- performance

e.g. in film, fiber and molding sections, etc.

Ceridust and Licocene

- new products - meet your demands

This means for all colorant suppliers striving for:

innovation

production of more critical applications (e.g. thinner films, finer fibers, etc.)

improvements in existing products

e.g. bleed-, light-, weather-fastness, color shade

improvements in existing technologies

less problems in quality control = stable production process, constant quality

fully compatible products

higher loadings of pigments and additives

Theory - improved pigment dispersionvisual assessment of dispersibility

non-wettable bad dispersible

poor dispersible good dispersible

The results of a mixture and the

assessment of the dispersibility

will be divided into four categories:

bad dispersible

non-wettable

poor dispersible

good dispersible

determination and comparison of pigment-dispersion-quality:

determination of the relative color yield (DIN 55986)

reduction in screen filter blockage / filter pressure value (DIN EN 13900-5)

determination of specks, spots and surface irregularities

- new products - meet your demands

the reduction of agglomerates of pigments within the master-

batch is one key factor in order to get a fine dispersion
