Frequently Asked Questions

What is latex?

Latex comes from the tropical rubber tree, Hevea Brasiliensis, that grows in southeast Asia, Africa and South America. The tree exudes a milky fluid that when tapped flows freely and can be harvested for up to approximately 30 years.

Where does your latex come from?

The raw material we use for our Dunlop latex comes from Sri Lanka. The tree farm is an FSC Certified (Forest Stewardship Council) farm.

Is latex sustainable?

Latex is a renewable resource. Our latex specifically used to make the mattress brands we sell all come from tree farms in Sri Lanka that are FSC Certified (Forest Stewardship Council).

How is Dunlop Latex made?

Ingredients for making natural latex rubber are fairly simple and few:

  • latex in milky fluid form
  • soaps
  • vulcanization agents
  • compressed air

The milky fluid is transformed through this process into a stable dispersion of rubber particles in water which is then dried to form air bubbles within the rubber particles.

These ingredients are put into a continuous foamer to be mixed which is then poured into a mold to shape it. The mold is then put into a vulcanization oven and steamed at 212ºF (or 100ºC). The latex piece that comes out of the oven is then washed and dried.

What is a vulcanization agent?

All latex, and there are many kinds, need to go through a process in order to turn the milky substance into a usable foam. Natural vulcanization agents are used consisting of small amounts of sulfur and a primary agent and zinc oxide as an accelerator.

The process also requires minuscule amounts of synthetic chemicals. Is this something to be concerned about? Perhaps not, test results from our latex show that the latex conforms to the Oeko-Tex™ Standard 100 Product Class 1. The amounts added are so minor and any off-gassing is tested for. If you are concerned about being allergic to the latex process or are curious if you have a true latex allergy, please order our free Raw Materials Sensitivity Kit.
