At Joseph Rubbers (India) Pvt. Ltd., we produce Skim Crepe Rubber as a by-product of our centrifuged latex processing operations. The skim latex contains approximately 3–4% rubber content and a higher proportion of non-rubber constituents. To recover usable rubber from this fraction, we employ a controlled acid coagulation process, typically using sulphuric acid, followed by thorough washing and mechanical processing.

The coagulated rubber is passed through a series of coarse and smooth rollers to form sheets, which are then dried and marketed as skim crepe. While not classified as a high-specification grade, skim crepe remains economically viable and is widely used in non-critical rubber applications due to its fast-curing nature and ability to produce hard vulcanisates.

This characteristic allows manufacturers to reduce accelerator usage, offering additional cost advantages in certain rubber formulations.

Standard packing is in 25 kg bales, either with one-side powder coating or wrapped in a polythene cover, depending on the customer's preference.

We currently produce approximately 10 - 20 tonnes of skim crepe per week, depending on production, ensuring consistent availability for bulk industrial use.
