ISNR 20 Processing of natural rubber into blocks similar to synthetic rubbers adopting cost effective and modern processing methods is a notable improvement in the presentation of dry natural rubber from India. This is in line with the consumer preference in the world rubber market for Technically Specified Rubber, which has the

Ribbed Smoked Sheets (RSS) are coagulated rubber sheets processed from fresh field latex sourced from well managed rubber plantations adopting modern processing methods. The grades available are shown in the table. The higher grades RSS 1x to RSS 3 are mainly used for manufacture of products for medical, pharmaceutical and engineering.

ISNR 20: All types of automobile tyres, re-trading materials, mats and other generalrubber products. Over 70 companies in India are involved in the production of ISNR grades, adapting TQM and BIS standards. The user does not have to check the quality parameters, as a clear test certificate is attached with its packing.

In India, block rubber is marketed with ISI specification, IS 4588 and therefore termed as 'Indian Standard Natural Rubber' (ISNR). This marketable form of natural rubber, is produced from Latex, Cup Lumps or Field Coagulum.

ISNR-20 (TSR20) – Mostly manufactured from shell scrap, tree lace and cup lumps. Skim Crepe (Skim Block) is a crinkly lace rubber, obtained when coagulated latex or any form of field coagulum (tree lace, shell scrap, earth scrap etc.) is passed several times through heavy rolls called crepers and then air dried at ambient temperatures.

Natural Rubber (also known as India rubber, gum elastic, and caoutchouc) is an elastic substance obtained from the latex sap of trees, especially those belonging to the genera Hevea and Ficus. It is the milky sap found in the bark of the tropical trees. Technically speaking, natural rubber is an elastomer or an elastic hydrocarbon polymer.

Indian Standard Natural Rubber (ISNR) / Block Rubber. Processing of natural rubber into blocks similar to synthetic rubbers adopting cost effective and modern processing methods is a notable improvement in the presentation of dry natural rubber from India.

ISNR production includes a series of unit activities such us sorting, pre-cleaning, blending, drying and packing. Palappillil group delivers products of high quality and value, to make sure customer satisfaction. The group manufactures various grades of ISNR (ISNR-20) from field coagulum which has much demand in tyre sector.
