Our range of slip additives and anti-blocking agents is one of the world's largest. These products, which trade under the names Armid® and Armoslip®, are also used as processing aid for elastomers.
Improved mixing, extrusion and calendering behavior
They reduce compound viscosity, thereby improving mixing, extrusion and calendering behavior of elastomers. Moreover, the reduced friction and consequential improved flow properties result in decreased mold contamination and easier demolding.
In vulcanized end-products these products migrate to the polymer surface. The solid lubricating layer formed reduces friction and adhesion with other materials, thereby providing excellent slip and anti-blocking performance.
Armowax® W-440: the best processing aid for highly filled polymer compounds
Armowax W-440 is a low-melting polymeric ester with a comb-like structure. Showing a perfect balance between internal and external lubrication, it is the best dispersion and processing aid for highly filled polymer compounds available.
The unique characteristics of Armowax W-440 are based on a combination of hydrophilic and hydrophobic groups present in the molecule. This combination provides improved wetting of the filler surface by the polymer matrix, thereby ensuring optimum dispersion of inorganic fillers such as calcium carbonate, talcum, carbon blacks or glass fibers.
The good compatibility of Armowax W-440 with polymers, combined with its low melting point, improves flow properties of compounds during processing. If a standard dispersion aid does not give you the performance you need, try Armowax W-440.
Our range of processing aids for elastomers
We also offer a range of processing aids for elastomers. Examples include Armeen® 18D and Perkaguard® TBHQ.
