NATURAL RUBBER

The dried material is then baled and palletized for shipment.

Naturally coagulated rubber (cup lump) is used in the manufacture ofTSR10 and TSR20 grade rubbers. The processing of the rubber for thesegrades is basically a size reduction and cleaning process in order toremove contamination and prepare the material for the final stagedrying.

Latex is generally processed into either latex concentrate formanufacture of dipped goods or it can be coagulated under controlled,clean conditions using formic acid. The coagulated latex can then beprocessed into the higher grade technically specified block rubberssuch as TSR3L or TSRCV or used to produce Ribbed Smoke Sheet grades.

The latex will coagulate in cup if kept for long. The latex has tobe collected before coagulation. The collected latex is transfered into coagulation tanks for the preparation of dry rubber or transferredinto air tight containers with sieving for ammoniation. Ammoniation isnecessary to preserve the latex in colloidal state for long.
