What are the considerations for filler selection when using PP flame retardants?

2016-12-16View Original

Thread Content

When modifying and granulating PP flame retardants, talc or barium sulfate can be added as fillers, with a typical particle size of 1250 mesh! Calcium carbonate cannot be used, and calcium carbonate must not be present in talcum powder either!

For PP flame retardancy, octabrominated ethers or MHB are generally used

It’s not that calcium carbonate can’t be used at all; in moderation, it’s possible to come up with a suitable formula.
