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
