Special Features and Benefits

The additive stabilizes the foam in mechanically foamable PVC plastisols and is particularly characterized by the formation of a fine, homogeneous and open-celled foam structure. This makes it possible to achieve a very good resistance to compression set. Compared to soap-based foam stabilizers, by using BYK-8020 it is possible to achieve a drier touch and a reduced water uptake of the gelled PVC plastisol.

Recommended Levels
1-4 phr additive (as supplied) based on the PVC resin. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions: The foam stabilizer should be post-added to the finished PVC plastisol whilst stirring slowly. It can also be injected directly into the mixing head of the mechanical foam mixer.
