Thin white crepe

Thin (about 1 mm thick) and thick (3-5 mm thick) pale crepes (TPC) and thin white crepe (TWC) are still produced from field latex in Sri Lanka. Sheets of sole crepe, up to 15 mm thick, are made by laminating sheets of white or coloured crepe. The demand for pale crepe is declining and will continue to decline, its place being taken by the teehnieally specified grades of block rubbers.

There are several visually graded latex NRs, including ribbed smoked sheets (RSS) and crepes such as white and pale, thin and thick brown latex, etc. Two types of raw NR are field latex and raw coagu-lum, and these two types comprise all NR ( downstream ) grades. Depolymerized NR is used as a base for asphalt modifiers, potting compound, and cold-molding compounds for arts and crafts.
