Useful information

Natural rubber latex

Natural rubber latex is primarily obtained from scratching the bark of the Hevena-Brasiliensis trees, which are planted in plantations in the tropical belt. The elastic component of this tree sap is the cis1.4 molecule polyisoprene. After tapping, the milk sap is freed from parts of the bark, centrifuged and the latex content is increased to 60%. Stabilizers such as ammonia TMTD make the latex transportable.

Coagulate coagulation

Coagulation: This term describes the transition from the liquid to the solid state of natural rubber latex.

Vulcanize vulcanization

Describes the chemical process of crosslinking the long-chain latex molecules through sulfur bridges. In addition to this classic vulcanization, crosslinking is also possible using peroxides and radiation energy.

Ammonia-free latex

There is no ammonia in the latex.

Low-ammonia latex (LATZ), LA latex

This type of natural rubber latex is stabilized with a maximum of 0.29% ammonia.

High ammonia latex (HA latex)

This latex is stabilized with an ammonia content of 0.6%.
