Fillers

Fillers are materials used for special functions or to reduce cost of composite parts. You can choose suitable fillers for your application from the list below. 

Döküm Tipi

Thixotropy Additives Wacker HDK N20

Fumed silica functions as a thixotropic additive and increases viscosity of resins and gelcoats while preventing sagging on vertical surfaces when added to resin systems.

Heat & Electricity Conductive Fillers AL-100 / AL-200 / AL-300

Polyester resins have very low heat and electrical conductivity values. It is possible to incorporate aluminum powders inside their matrix to allow for heat and electricity conductivity. This filler can be used in molds for acrylic sheets, solar panels or satellite receivers. It is possible to obtain a metal like appearance from castings with aluminum powder. AL-100, AL- 200 and AL-300 each have different particle sizes.

LP / LSA Thermoplastics Additives LSA / LSB / LSC

LSA is a polystrene solutions for hot press applications. It provides low shrinkage and floating. LSB and LSC are polyvinyl acetate solutions. They are low profile (LP) additives that provides better surface quality and low shrinkage. It is possible to obtain Class A surface quality in SMC formulations which contain LP additives LSB and LSC.

Economical Fillers Calcite and Dolamite

Calcite and dolamite are fillers used to lower the cost of composite parts by replacing or decreasing the volume of resin in the structure, also enabling to have more rigid parts. These fillers can decrease elongation values. Primary application areas are artificial marble and composite wall panels.

Weight Reducing Fillers Expancel 551

Expancel 551 is a small sized hollow plastic filler particle which decreases the density of the formulation. It is possible to use Expancel 551 in easily sandable formulations and where weight reduction is critical.

Weight Reducing Fillers Glass Microspheres

Microspheres are hollow glass spheres which decrease the density of formulations and can be used in putty formulations because of their small particle sizes, around 70μ .

Improve Abrasion Resistance Corundum

This filler is a crystal form of aluminium oxide (Al₂O₃), which is one of the hardest minerals in nature with a mohs value of over 9. It is possible to incorporate this filler into resin or sprinkle it on the surface of wet resin.

Flame Retardant Fillers Apyral 16

Aluminium hydroxide (Al(OH)³) filler is the most common filler for flame retardant applications. Flame retardancy increases as the ratio of ATH increases in the formulation. Apyral 16 and Alolt 2AF have the optimum particle size distribution enabling higher loadings to the formulation with a reasonable cost value.
