BEST T.P.S. is the only product in the market combining both fibres and rubber crumbs in big quantities. In reality it is rubber in liquid form. Most of the sealants in the market contain either crumbs or fibre with a very small quantity of rubber dust. The advantage of our product is that fibres create strong patches and rubber crumbs seal bigger holes. After many years of research and development in some of the highest quality universities of Europe, we have concluded to our secret formula. The achievement of our production is to maintain equal dispersion of fibres and rubber crumbs in a stable solution, which never breaks - down.
The reasons why all substances should be equally distributed into the liquid are many but can be split in two groups: a. Dispersion in calm (in the pail) b. Dispersion in motion (in the wheel) It is very difficult to keep materials of different specific gravity equally suspended into a liquid. Fibres and rubber crumbs have much different specific gravity (weight/volume) but also much more difference in weight/total surface of the molecule. In this characteristic the molecule difference is enormous significant, since the fibre is extremely fin and the rubber is chunky. As a result of the above the solution will split after some idle time. So when you pump into the tyre, you will pump more quantity of rubber or more quantity of fibre depending if you pump when the pail is completely full or half full or almost empty. This makes the liquid not functioning properly.
Coming to the function into the tyre, if the molecular forces are not able to keep the substances in position, the liquid will split and brake down. As a result you will see in old tyres with older generation of sealant, some black "water". This black liquid cannot function as a sealant any more, so after a short time it is useless.
