Kettlitz Chemie Mediaplast AT

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.

Dosage

For compounds based on chloroprene, low dosages (≤ 1 phr) are generally sufficient because Media-plast AT is very effective within this polymer. A dosage of about 0.5 phr is recommended for sticky EPDM compounds with a high plasticizer content. The dosage for polar polymers should be 1–3 phr depending on the stickiness of the compound. The dosage for polar polymers should be 1–3 phr depending on the stickiness of the compound

Uses

In ACM and VAMAC compounds, tests have shown a significant improvement of rubber compound flow, whereas physical properties (e. g. compression set) are only slightly influenced. Mediaplast AT is based on highly effective polar substances. Therefore it should only be used in small amounts (max. 1 phr) with low polarity polymers.
