About Pure Cup Lump

PRODUCT DESCRIPTION

Cup lumps are the coagulated rubber latex collected from rubber trees in cups during the tapping process. These lumps are then sun-dried or air-dried and used as raw material for further processing into TSR (Technically Specified Rubber) or other industrial rubber forms. They are in high demand for tire manufacturing, footwear, gaskets, and various rubber-based products.
