What are some properties of HSBR rubber

Natural latex and natural rubber: material science

Mattresses and toppers, yoga mats, rubber boots, car tires: natural rubber is the basis of many everyday objects. Behind it stands the Rubber tree Hevea brasiliensis and its milky juice. Where the Difference between synthetic latex and natural latex is what makes natural latex mattresses so special and you can find out a lot more here.

What is natural rubber?

Natural rubber is a component of the natural rubber tree sap. This material has been used for all kinds of useful objects since 1600 BC. So there must be something special about this one renewable raw material, but what exactly - and how do you ensure that natural latex products have a long service life?

Properties of natural rubber

The processing of natural rubber is not that easy, as the raw material quickly becomes brittle in the cold and sticky in the extreme heat. If handled correctly, however, it is even more beneficial more advantageous properties With. Natural rubber is:

  • Durable
  • Robust
  • Easily malleable
  • Antiseptic
  • Regrowing
  • Water repellent

Thanks to its good malleability, natural latex can be processed into many products. Among them are particularly high quality Natural rubber mattresses. You can find more information on this below in the text.

From yoga mats to rubber boots: use of natural rubber

Those who like to do yoga or use gymnastics mats during sports have probably already benefitedYoga mats made of natural rubber belongs. Their advantage is that they are greatnon-slip and breathable are what makes them good companions for sporting activities. Natural rubber yoga mats are a little heavier than plastic variants.

This is of course an omnipresent form of use of natural rubber Rubber from car tires. Are equally popular Natural latex rubber boots. The English slang term wellies goes back to the first form of the rubber boot, the "Wellington Boots" (1824). Today there are Natural rubber rubber boots in a soft or hard design. What all variants have in common, however, is that, thanks to the rubber coating, they can withstand any weather change.

By the way: chewing gum also contains a certain amount of natural rubber and this is what gives it its characteristic, chewy consistency. Theoretically, you could drink the rubber milk in its original form without hesitation!

Care of natural rubber

Natural latex products are generally said to have a long service life, but they should also be treated with appropriate care. Specifically, this means: a latex mattress or a mattress pad made of natural latex is best turned or turned every month. Ideally, two people do this together, as the mattress is one high weight Has.

Natural rubber boots of course have to be able to withstand a lot in cold and wet outdoor areas. This works better in the long run if you have the boots Spray off with a cold, hard jet of water immediately after useso that stubborn dirt can be loosened. Alternatively, you can remove the dirt with a light soapy solution and a soft cloth.

The Clean natural rubber yoga matis just as easy: salt water and a soft, damp cloth disinfect the mat. Then wipe the surface with clean water to prevent white edges. However, the rubber mat does not tolerate a washing machine, oils or a lot of water.

So natural latex or natural rubber is a very versatile material - but what about the terminology? Can rubber and latex be used synonymously? And why invest in natural latex at all, when it does synthetic latex gives? Time for more answers!

What is latex?

Natural rubber and natural latex are fundamentally inextricably linked. Because Latex is made of:

  • 60-76 percent water
  • 25-35 percent rubber
  • Resins
  • Proteins
  • Minerals

Natural latex products are based on natural rubber, which in turn is obtained from the sap of the rubber tree.

Natural rubber extraction and processing

The rubber tree, Hevea brasiliensis, originally grows in Central America. Today, however, the rubber demand is mainly due to Trees in Asia and Africa covered. Its bark is scored in an arc shape so that the milky sap emerges along the cutting direction as a natural protective mechanism for the tree. It is caught in vessels that are attached to the tree.

The latex milk is then processed into usable latex. The end product can be solid, liquid or powder, depending on whether it is to be processed on site or transported. In processing, the Filtered out rubber portion and mixed with stabilizers.

The so-called vulcanization goes back to a process that was introduced in 1839 by Charles Goodyear was developed. Natural rubber is treated with sulfur, peroxides, metal oxides and other substances.

This is how, for example, arises Dunlop latex: The latex milk is foamed and poured into a steel mold that contains heating elements.

After the mold is closed, the pens heat the liquid to 100-120 ° C. This creates microscopic air chambersthat make the natural latex so breathable. Subsequent washing and drying remove protein residues.

Next to it is that Talalay latex: Here the latex milk is alternately foamed and shock-frozen. This makes the end result particularly open-pored because the air bubbles burst. These types of latex processing are particularly useful for Manufacture of mattresses at.

Natural latex versus synthetic latex: differences

The term natural latex initially sounds like a very sustainable product, and in its pure form it is. However, the designation is subject to no legal norm. In theory, a “natural latex” mattress that only consists of 2 percent real natural rubber can also bear this name. After all 60 percent of global demand of latex is covered by the synthetic variant.

Actually, if you want to be on the safe side 100% natural latex To get then the price is a good indication: one Natural latex mattress made from 100 percent natural rubber cannot be cheap because the manufacturing process is very complex.

But: What is the difference between the natural variant and the artificial one? Probably the most important factors are that natural latex

  • is more flexible and breathable
  • Better regulation of moisture
  • is produced without harmful chemical additives
  • can be recycled
  • Only 10 percent of the energy that is used in the production of synthetic latex is required in production

Synthetic latex is also problematic from an environmental point of view, since the material consists of petroleum and thus a finite raw material. From a sustainable perspective, the decision can only be made in favor of one hundred percent, certified natural latex.

Natural rubber mattresses and toppers

Natural rubber mattresses and corresponding cushions are no longer an insider tip when it comes to bed furnishings, and for several good reasons.


Quick and easy to your personal comfort mattress

Advantages of mattresses and toppers made of natural latex

Consist of natural rubber in a mattress or topper thousands of small air chambers. With every movement during sleep, they release air completely silently or take in air again when the load disappears.

A natural latex mattress is with it highly point elastic And last but not least, well suited for people who quickly struggle with back problems. Because on a point-elastic lying surface, the natural double S-shape of the spine well supported; The back, neck and intervertebral discs can regenerate.

The high density a natural latex mattress also determines the point elasticity. A mattress only has this property from one Density of 60, but with a high-quality natural latex mattress, the value is a lot higher. Incidentally, this orthopedically extremely useful lying surface remains preserved in the long term: You don't have to worry about the sagging effect with a good latex mattress.

Thanks to the air chambers and the resulting breathability, mattresses and toppers are made of natural latex too very suitable for those who are allergic to mites. Because the tiny animals cannot settle in the very dry, dust-repellent bed climate.

What to do if you are allergic to natural latex?

First of all: it has not yet been scientifically proven that natural latex can trigger allergic reactions. If these occur when sleeping on a natural rubber mattress, it may be due to the fact that the Protein fibers not removed thoroughly enough were. Alternatively, a high synthetic latex content cause allergic reactions.

A high quality, carefully processed natural latex mattress is even more anti-allergic because it repels dust and mites. As is so often the case, quality is also important with natural rubber products - and if you choose carefully, you are guaranteed to benefit from the properties of sustainable, one hundred percent natural latex
