From Hevea tree sap to finished fluorescent band — the complete raw material and process guide from Kaniskaa Rubber Industries, Coimbatore.
Natural latex is a milky suspension of rubber particles in water produced by Hevea brasiliensis trees through a process called tapping. Kerala produces ~90% of India's natural latex.
The Para rubber tree, cultivated across Kerala, Karnataka and Tamil Nadu. Each tree yields 100-200ml of latex daily.
Bark is cut in a V-pattern at dawn. Latex flows naturally into collection cups below the cut.
Field latex is centrifuged to increase dry rubber content from ~30% to 60% for manufacturing.
Latex is blended with vulcanising agents, accelerators, anti-oxidants and fluorescent pigments.
Heat treatment at 130-150°C creates sulphur crosslinks between rubber chains — delivering elasticity and durability.
Vulcanised rubber sheets are cut to precise widths using high-speed machines.
| Ingredient | Role | Safety |
|---|---|---|
| Natural Latex | Base rubber (100% Hevea) | Safe — plant-derived |
| Sulphur | Vulcanisation — creates crosslinks | Safe at vulcanisation levels |
| Zinc Oxide | Activator for vulcanisation | Safe at standard levels |
| Stearic Acid | Processing activator | Safe — food-grade fatty acid |
| TMTD/MBT Accelerators | Speed up vulcanisation | Safe at trace levels in finished product |
| Anti-oxidants | Prevent ozone and UV degradation | Safe — extends band life to 3+ years |
| Fluorescent Pigments | Red, Green, Yellow colour | Safe — non-toxic at levels used |
Kaniskaa Rubber Industries does not use lead, cadmium, phthalates or harmful heavy metals in any part of our manufacturing process. Our bands are food-safe and biodegradable.
The primary raw material is natural latex — a milky sap harvested from Hevea brasiliensis trees. It is compounded with sulphur, zinc oxide, accelerators and anti-oxidants, then vulcanised to create elastic rubber bands.
Kerala accounts for ~90% of India's rubber production. Coimbatore-based manufacturers like Kaniskaa Rubber Industries source latex directly from Kerala — just 80km away — getting the freshest, highest-grade material at the shortest supply chain.
Natural rubber band manufacturing uses sulphur (vulcanisation), zinc oxide (activator), stearic acid (activator), TMTD/MBT accelerators and anti-oxidants. Fluorescent pigments add colour. Reputable manufacturers use no lead, cadmium or phthalates.
