The quality control early starts since the first step, before acquiring the “Raw Material” from local farmers, LATEX sample is analysed in our laboratory.

Filtering phase will eliminate particles and impurities from latex. Diffrent chemical composition is added to latex depends on type of STR we are planning to produce.

The latex is then poured on a serie of long mould,after chemical reaction, latex will change it status from liquid to solid in about 12 hours. After this step we obtained a very concentrate latex in form of thick sheet rubber.

From Thin Sheet Rubber will be shed to small pieces of 2-3 millimeters by schredding machine.

After passing through a 110 degrees celsius oven, the small pieces will latex transform into blocks.

The block rubber weight is precisely set to 33.33 kgs per block.

The finished block rubber or STR is packed in plastic film, the package is enforced by a structure of wood to protect it content during the transport and easy for handling.
