Summary

“Bloom” is caused by the migration of solid or liquid compounding materials which have a limited solubility in the polymer matrix.

Bloom includes dry bloom and wet bloom which is also known as “exudation”, “bleeding” or “oily bloom”.

Very common, bloom refers to the initial formation of star-shaped clusters when solid compounding materials re-crystallize at the vulcanisate surface. This is due to the fact that many of the rubber compounding materials have limited compatibility with the elastomer and separate out at the latest after vulcanizing and subsequent cooling to room temperature.  Blooming is a diffusion controlled process.

Topics Covered:

- Simple Tests to identify bloom type

- Color changes and their significance in “Bloom” analysis

- Blooming of Crystalline Substances 

- Bloom from components commonly use in rubber compounding: sulphur, accelerators, retarders, etc
