Frequently Asked Questions

There are no problems with using Innovox in combination with either magnesium oxide or calcium carbonate. If you would like advice on either, please contact us.

Innovox is usually supplied in weight defined EVA low melt sachets, e.g. 1kg. These are ideal for use with a Banbury type mixer. For open mill mixers, Innovox can be supplied as a powder or as Innovox MG MicroGranules. If you would like information on product choice please get in touch.

Yes, we can. Innovox MG MicroGranules can be used as a direct replacement for Kezadol, Rhenogran or other desiccant granules. Ask your distributor for details or please contact us.

Yes, Innovox is used by many other compounders worldwide. Ask us if you require details of reference customers.

Innovox can replace powder or granules as a direct 1:1 and will perform better in both cases. If you are using granules, you can use 20% less Innovox and still achieve better results. Innovox is 100% calcium oxide powder whereas granules are approximately 80% calcium oxide powder. Ask to see our test reports or contact us for advice.

We have conducted extensive testing on Innovox with external laboratories (such as Artis and ACE Consultants) and can supply test reports on request. We can also provide reference customer details within your own field of application. Ask to see our test reports or contact us for advice.

Calcium oxide is classified as a Generally Recognized As Safe (GRAS) substance by the FDA. Innovox FG is 100% calcium oxide powder. As a calcium oxide powder combined with food contact approved dispersion additives, Innovox 95F is suitable for food contact applications.

Innovox is mainly used in sulphur cured systems including EPDM, although it is suitable for most applications where there is an issue with moisture or acidity. Please contact us for recommendations regarding your proposed use.

Innovox is usually supplied in weight defined EVA low melt sachets, e.g. 1kg. We do offer several other sizes and can also make special or bespoke packs. Ask your distributor for further details or please contact us.

Addition level will depend on the moisture levels within your compound. In practice, the typical dose rate for Innovox FG or 95 would be around 5 phr. If you would like further advice on addition levels, please contact us.

Typically, Innovox is added at the start of the mixing process. For high humidity environments, moisture may often be absorbed if compound is stored – to overcome this, Innovox can be added near the final mix. If you require advice on addition points, please contact us.

Innovox is made from calcium oxide produced in our own lime kilns on site in the UK. Search for Melton Ross in your web browser and you can access a satellite view of our site. For further information, please contact us.

Leading compounders have found that when switching to Innovox they produce better quality compound with greater consistency and fewer scrap or quality control rejects. More compounders are recognising the Innovox advantage and specify Innovox in all new and existing formulations.
