We’ve developed Birchset® CR, a food contact approved cure stabiliser and compression set reduction additive. Birchset® CR eliminates increased compression set or reduced vulcanisation – without compromising rubber compound performance.
Birchset® CR is specially formulated to overcome the adverse effects of using high doses of calcium oxide for moisture removal in rubber compounds. Birchset CR should be used in combination with Innovox to ensure optimum rubber characteristics in high moisture compounds.
In higher humidity environments, or where high moisture fillers are used, higher levels of Innovox addition may be required to overcome compound porosity. This can lead to reduced vulcanisation or increased compression set values – but with the help of Birchset® CR, you can eliminate these negative effects.
