Is latex the same as rubber?

Rubber and latex are not the same thing, but many people use the words as if they are the same. Latex is the milky white sap of rubber trees, which is found beneath the bark of a mature rubber tree. So how is rubber made and does rubber contain latex? Yes, it certainly does and we will look at the production processes of how is rubber made.

Does foam contain latex?

Natural latex is made from sap from the rubber tree, which is whipped into a froth, then baked into a foam. Some memory foam manufacturers have added even more chemicals—called “cooling chemicals”—to attempt to address this overheating problem. And this why many people choose natural latex instead.

Which latex is better?

Latex is environmentally friendly and made of natural, biodegradable material. Because latex gloves are made of natural rubber, they are less durable than nitrile and more susceptible to harsh solvents. Features Biodegradable Close-fitting for excellent range of motion Superior protection from viruses and bacteria Comfortable for long-term wear

What is foam latex?

Foam latex or latex foam rubber is a lightweight form of latex containing bubbles known as cells, created from liquid latex. The foam is generally created though the Dunlop or Talalay process in which a liquid latex is foamed and then cured in a mold to extract the foam.

What is the structure of latex foam?

Structure. Latex foam is a form of latex that is lightweight and expanded. Cellular air bubbles are created inside liquid latex, and they can be shaped into different shapes and sizes. The extension of the foam is defined by the amount of air inside of these cells.

What is structural enhancement foam?

Structural enhancements are applied to a foam by making different choices of polymers used for the foam or through the use of fillers in the foam. Historically, natural rubber latex is used for the foam, but a similar commercial contender is styrene-butadiene latex, which is especially designed for use in latex foams.

Why does foam show a linear Hookian increase in stress?

This happens because the gas contained in foam cells is compressed, and the walls of the cells maintain their structure. In the second region, the cell walls are being crushed, and no additional stress is experienced, and so the stress plateaus.

Why use latex foam in upholstery?

Due to their energy absorption properties, latex foams are useful for transportation applications , such as in packaging to decrease impact on the shipped product or in vehicle upholstery. While packaging foams may be single-use with low resistance to dynamic fatigue, upholstery tends to benefit from being denser and more resistant to fatigue as it absorbs lower impacts but needs to do so more repeatedly.

How to measure density of latex foam?

This density can be measured regularly by taking a volume and mass measurement of the material. For a volume measurement of irregularly shaped foam, the foam pieces can be coated with wax and inserted in a known volume of water to measure volume change in the container. The purpose of the wax is to prevent water permeation into the foam, which may lead to a lower perceived volume (and higher perceived density as a result) if not accounted for. The density of a foam decreases as the expansion of the foam increases. Expansion, in turn, relates to the amount of air inside the cells of the foam. The more air inside the cells, the larger the expansion.

Why do you use wax in foam?

The purpose of the wax is to prevent water permeation into the foam, which may lead to a lower perceived volume (and higher perceived density as a result) if not accounted for. The density of a foam decreases as the expansion of the foam increases.

Memory foam conforms to your body, while latex is bouncier and more eco-friendly. Decide which features are most important for you and your quality sleep, and them make a decision based on the mattress type that meets most of your needs.

What is synthetic latex?

Synthetic latex comes from a mix of materials, most often a type of plastic called styrene-butadiene rubber (SBR). Latex can be produced with two different methods: Talalay and Dunlop. In a Talalay latex mattress, the tree sap fills a mold only partially, with the rest of it getting filled with air.

What are the best mattresses?

Keep in mind that there’s more to mattresses than their materials, though. You’ll also want to consider: 1 Firmness. Many mattresses come in firm, medium-firm, or soft varieties. 2 Height. A thicker mattress will last longer than a thinner one. 3 Price. Mattresses can be pricey, though some bed-in-a-box brands can be less expensive. Be sure to consider the reasons for a higher price tag before you make a purchase. 4 Cooling features. Especially if you choose a memory foam mattress, you may want to keep an eye out for cooling features like gel foam. 5 Size. Make sure you choose a size that will fit well in your space.

How to prevent overheating on memory foam mattress?

To help prevent overheating, some mattress makers add cooling features to their memory foam mattresses . Commonly, mattress makers infuse the foam with gel for added cooling. The gel can also make the bed bouncier. Some brands also add perforations to the foam to help allow air to circulate through the mattress.

How long does a Dunlop mattress last?

Dunlop latex is more durable, denser, and less expensive than Talalay. Latex mattresses can have a life span of about 20 years.

What is memory foam?

Memory foam, also known as viscoelastic foam, is a type of polyurethane foam. Polyurethane foam is typically made of petroleum (crude oil), though it can also be made from plant oils, like soy. Memory foam slowly compresses when pressure is applied, so it will shift to conform to your body when you lie on it.

Does memory foam feel soft?

Most memory foam mattresses feature several layers of foam. Depending on the types and densities of the foam layers, the mattress may feel soft, firm , or somewhere in between. Memory foam is sensitive to heat, so performance can vary depending on temperature and humidity.

What is latex foam made of?

Structure

Latex foam is a form of latex that is lightweight and expanded. Cellular air bubbles are created inside liquid latex, and they can be shaped into different shapes and sizes. The extension of the foam is defined by the amount of air inside of these cells. Lower density and more extended foams tend to have cells which are more polyhedral, while less extended foams tend to have more spherical cells.

Creation

To create foam latex, a liquid latex base is mixed with various additives and whipped into a foam, then poured or injected into a mold and baked in an oven to cure. The main components of foam latex are the latex base, a foaming agent (to help it whip into a froth), a gelling agent (to convert the liquid foam into a gel), and a curing agent (to turn the gelled foam latex into a solid when baked). A number of additional additives can also be added depending on the required use of the foam.

Properties

In general, latex foams have lower density than the original polymer they are made of. This density can be measured regularly by taking a volume and mass measurement of the material. For a volume measurement of irregularly shaped foam, the foam pieces can be coated with wax and inserted in a known volume of water to measure volume change in the container. The purpose of the wax i…

Classification and Additives

Historically, natural rubber latex was used, and foams were produced using the Dunlop processes. Styrene-butadiene rubber latex rose to prominence once high-solids concentrates, which were designed specifically for foaming, began to be sold on the market. Properties of this polymer were fairly similar to natural rubber latex, so the competition between the two choices here is mostly econo…
