Products in Footwear: Processing Aid

AEROSIL® R 972 is hydrophobic fumed silica grade treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recomended for improving the sedimentation stability of defoamer dispersions as well.

AEROSIL® R 812 is hydrophobic fumed silica grade treated with HMDS (Hexamethyldisilazane). It can be used for sedimentation stabilization and due to its high hydrophobicity as defoaming agent.

K - STOFF 440 is an oleochemical wetting & dispersing additive that offers excellent wetting characteristics and does not allow to form of the agglomerates of pigments particles in color MB application.

K - STOFF O is primary amides specially developed as mold release & slip additives for rubber application. In rubber application, these amide waxes also act as a processing aid and/or additive to improve the surface properties of both natural and synthetic rubbers such as NR, NBR, SBR, EPDM, CR, etc.

Mosselman Castor Oil Hydrogenated (8001-78-3) is a white, odorless fat obtained by the hydrogenation of castor oil. It has very good compatibility with natural waxes. It is mostly used in the manufacture of calcium and lithium lubricating greases. These lubricating greases exhibit excellent resistance to oils and fats, water and solvents. It is also used as raw materi-al for solvent based coating systems, for alkyd resins and as processing aid for phenolic resins, poly-ethylene, PVC and rubber and as an additive in powder coatings. It is also of importance concerning the production of hot melts like paper additives. Finally it can be used as an ingredient in polishes (for cars, shoes, furniture) and in cosmetics (for creams, lipsticks,…).

Dispergator KB contains 25 % more active material and less moisture than Dispergator DS. It fa-vourably can be used in all rubber compounds which are intended to be cured by UHF, LCM or hot air. It also has good compatibility with most polymers.

Chengdu Silike Technology LYSI-100A is a powdered formulation with 55% ultra high molecular weight siloxane polymer and 45% silica . It is recommend to be used as processing aids in various thermoplastic formulations such as halogen free flame retardant wire&cable compounds , PVC compounds , engineering compounds, pipes, plastic/filler masterbatches..etc.

Haftolat or the dry form, Haftolat/P, are very effective process aids produced from EPM rubber. I

Chengdu Silike Technology LYSI-100 is a powder formulation which contains 70% UHMW Siloxane polymer dispersed in Silica . It is particularly developed for Polyolefin masterbatches/ filler masterbatches to improve the dispersion property by better infiltrate in fillers.

Hot polymerized SBR 1009 is recommended for use in calendared products such as slab soling for footwear, and in extruded mechanical goods where smoothness and controlled shrinkage are critical requirements. It is also widely used in sealants and adhesives.

Dispergator OX is a Polymer- and water-free granulated processing aid, suitable for all natural and synthetic elastomers, and especially helpful in polymer blends. Dispergator OX is particularly recommended for pressureless continuous curing processes, as it con-tains no moisture.

Mediaplast EV/F is an effective processing aid for the treatment of very sticky polymers, mainly EVA compounds. EVA types with a vinyl acetate content of more than 40 % tend to stick to open mills, internal mixers and even extruder screws.

Pertac/GR is a multifunctional process aid based on 1.2-polybutadiene converted into free-flowing granules.

Kettlitz-Dispergator FD is a highly effective processing aid for compounds in alimentary contact. It has been developed referring to the regulations of FDA and BfR XXI (former BGVV resp. BGA regulation). It is a combination of zinc salts and hydrocarbons in surface active agents.

Mediaplast WH-P is a Processing aid and homogenizing agent with non-staining properties in order to improve the stickiness of synthetic rubber compounds. Especially in NBR, EPDM, SBR and EVA the application of Mediaplast WH results in shorter mixing times and better homogeneity.

Haftolat or the dry form, Haftolat/P, are very effective process aids produced from EPM rubber. I

Hot polymerized SBR 1009AF is used in spray applied adhesives, calendared products, and extruded mechanical goods where smoothness and controlled shrinkage are critical requirements.

Mediaplast AT is a very effective process aid to improve flow properties and to reduce the tackiness of rubber compounds regardless of the polymer used. Processing of CR and ACM compounds in par-ticular is significantly improved by adding a small amount of Mediaplast AT. It improves the demolding properties of technical rubber parts. The sticking of uncured compounds to internal mixers, open mills and conveyor belts will be visibly diminished by the use of Mediaplast AT.

Mediaplast WH is a Processing aid and homogenizing agent with non-staining properties in order to improve the stickiness of synthetic rubber compounds. Especially in NBR, EPDM, SBR and EVA the application of Mediaplast WH results in shorter mixing times and better homogeneity.

Kettlitz-Dispergator SI/GR is a new generation of processing aid based on a silicone combination. The proc-ess aid has been developed especially for EPDM and EVA compounds to improve processability.

M.G. Polyblends SI-11 has developed 50% concentrate of ultra high molecular weight polydimethyl siloxane in polypropylene carrier for use of automotive interiors, appliances and all other applications which are using PP, Talc-filed PP, TPO's, Talc-filed TPO's as the base polymer. This masterbatch is mainly used for low gloss appearance along with good scratch and abrasion resistance.

MoldWiz® INT-1230 - A process aid additive with anti-static properties which is incorporated directly into the resin eliminating the need for an external mold release agent. Additional advantages include better resin flow, improved dispersion of other resin additives and faster cycle times. The complex polymeric nature of the process aid additive will not interfere with secondary operations such as printing or bonding.
