Frequently Asked Questions

A.

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

A.

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

A.

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 advice on product choice please contact us.

A.

Yes, 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.

A.

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

A.

Yes, Innovox is used by Hexpol, Cooper Standard and many other compounders worldwide. Ask us for details of reference customers.

A.

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.

A.

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

A.

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.

A.

We have conducted extensive testing on Innovox with external laboratories, such as Artis and ACE Consultants and can provide 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.

A.

Innovox can replace powder or granules as a direct 1:1 replacement and will perform better in both cases. If using granules, you can use 20% less Innovox and still achieve better results, as 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.

A.

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

A.

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 details or please contact us.
