Natural, blended, synthetic
Natural latex comes from rubber tree sap. Blended mixes natural with synthetic. Synthetic is petroleum-based.
Density and hardness
These define feel and durability. Compare in the same units.
Certification
Certificates are shown only with a valid number.
What to ask the supplier
The natural rubber percentage, the density and hardness, whether the sheet is moulded or cut, any certification number and the batch record. Test a sample for smell and recovery. Ask what additives are used if the product is for sensitive users.

| Natural percentage? | Feel, durability, allergy planning |
| Moulded or cut? | Consistency |
| Density and hardness? | Compare like with like |
| Certification number? | Verification |
| Batch records? | Traceability |
Latex and allergy
Natural latex can cause reactions in people with a latex allergy. Buyers supplying healthcare or care settings should ask about latex content and offer alternatives. Clear labelling avoids problems.
Detailed guidance
Latex quality depends on the rubber source, the process and the finish. Ask whether the sheet is natural, blended or synthetic and by what percentage, how it is made (moulded or cut), its density and hardness, and the batch record. If a certificate is claimed, check its number with the issuer and its scope.
For products used by sensitive people, such as in healthcare or hospitality, consider labelling and alternatives for latex-allergic users. Request a sample, assess smell, recovery and surface, and test ageing if durability is key. Store latex away from direct sunlight and heat. Keep records so you can trace a problem to a batch.
Worked example (illustrative figures)
A buyer sees two latex sheets at similar prices. One is 100 percent natural, the other is a blend with 30 percent natural rubber. The buyer asks for natural percentage and certificate numbers, and chooses based on the product claim it wants to make on its label.
Frequently asked questions
Is 100 percent natural latex common?
Many products are blended; ask for the percentage.
