Natural rubber
Natural rubber (NR)
Natural rubber is made from the latex sap of the rubber tree. It isn't plastic under our definition, as long as it isn't blended with synthetic rubber. It's used for teats, soothers, gloves and hot-water bottles, but some people are allergic to it.

- Type
- Natural rubber
- Found in
- baby bottle teats and soothers, washing-up gloves, hot-water bottles, elastic bands, yoga mats and mattresses (natural latex), balloons
- Heat
- Not for cooking. Heat, oil and sunlight make it perish faster.
- Recycling in the UK
- Not collected in household recycling. Worn-out items go in general waste.
What it is
Natural rubber comes from latex, the milky sap of the rubber tree (Hevea brasiliensis). The latex is collected, processed and usually vulcanised, heated with sulphur, to make it stronger and more elastic.
Is it plastic?
No. Under our definition, natural rubber, including vulcanised natural rubber, isn't plastic, because its polymer is made by a plant, not synthesised. The catch is blends: many "rubber" products are partly or wholly synthetic rubber, such as SBR, EPDM, neoprene or nitrile, which do count as plastic. Look for "100% natural rubber" or "natural latex", and ask the brand if it isn't stated.
Where it's useful
- Baby teats and soothers: natural rubber is the main alternative to silicone. It's softer, and it wears faster, so check and replace teats regularly.
- Washing-up gloves and hot-water bottles: natural rubber versions are easy to find.
- Mattresses and yoga mats: natural latex foam, though some products mix in synthetic latex.
Latex allergy
Some people are allergic to proteins in natural rubber latex. Reactions range from itching, rash and swelling where it touches the skin to, rarely, severe allergic reactions (anaphylaxis). Healthcare workers and people who've had many operations are more at risk. If you or your child have a latex allergy, avoid natural rubber products and follow your clinician's advice; silicone or synthetic alternatives exist for most uses.
Care
Natural rubber perishes over time, faster with heat, oils, fats and sunlight. Keep teats and gloves out of direct sun, don't use them for cooking, and replace them when they become sticky, cracked or swollen.
Disposal
Natural rubber isn't collected for recycling at home. It will eventually break down, but not quickly, so put worn-out items in general waste.
