Ash content	≤ 0.1 %	Average particle size, µm	≤ 12µm

Use Characteristics

Organic blowing agent HiDispersion AC-75 can be used in all types of sponge, particularly adapted for microcellular expanded products where it develops an extremely fine, uniform cell structure. Relatively high decomposition temperature of 200°C to 210°C, makes it useful where pre-mature decomposition during processing is a hazard. Imparts no odor to finished products.

Processing Advantages

The thermosofting, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective raw material AC is assured. AC-75 allows for quicker and easier incorporation into the compound either late in a banbury mix cycle or in a open mill finishing operation.

Dosage levels

Normally 1 to 10 phr based on the requirements of the density of sponge.

Applications

All types of sponge rubber articles.

Packing

Net 25 kg cartons with plastic inner.

Storage stability

Under cool (< 35 °C), dry (< 50 % relative humidity) conditions, sealed original containers have a shelf-life of 1 year..

Handling

Consult material safety data sheet (MSDS) for additional handling information.
