Does sponge cushion have formaldehyde, does sponge have formaldehyde

The sponge mat has no formaldehyde. Sponge is a polymer material, in which there is no formaldehyde, there are more pores in the sponge, water absorption and air absorption are good, it is easy to lead to the breeding of bacteria, mites and other microorganisms in the sponge, it is recommended to dry for a long time.

The sponge itself does not contain formaldehyde, but in the production process, in order to increase the flexibility of the sponge, formaldehyde-based finishing agents will be used for finishing, so the sponge will contain trace amounts of formaldehyde. However, these formaldehyde levels are controllable and will not cause harm to humans under normal use conditions.

If you want to reduce the formaldehyde content in the sponge, you can remove it by ventilation, drying, etc. At the same time, pay attention to changing or cleaning the sponge regularly to keep it hygienic and safe.

Ordinary sponge mats are not toxic, because sponge mats are made of foamed plastic polymers or cellulose fibers, which do not contain toxins, sponge mats need to be cleaned regularly, wet them and apply detergent to rub them, and sponge mats need to be dried regularly and sterilized with ultraviolet rays.

Quality identification of sponge mats:

1. Look, the sponge process is mainly divided into two categories: foaming and PU. Doping makes the fake sponge foam uneven and the holes are large. Whereas, pure sponge has small and uniform holes.

2. Touch, the pure sponge feels delicate and smooth, and the doping makes the fake sponge feel rough and the elasticity is very poor.

3. Extrusion, which seems to be a sponge of the same thickness and hardness, is doped so that the fake sponge is prone to depression once squeezed, and it cannot be bounced up for a long time after sitting down; The pure sponge has strong support strength, and it is difficult to deform after long-term extrusion.

4. Doping makes the fake sponge greatly reduce the cost due to the addition of stone powder, and the cost is low; The polyurethane material used in pure sponge is more expensive than adulterated sponge.

5. Lifespan, adulterated sponge is easy to slip off because of the addition of stone powder and hand-picking; Pure sponge is durable.

6. Comparison of tensile strength between adulterated sponge and pure sponge, the longer the sponge with the same appearance, the better the tensile strength.

7. Comparison of the breaking strength of adulterated sponge and pure sponge, the sponge with the same appearance, the pure sponge can have strong load.

The sofa is like the second bed in the house, and the first thing you do when you get home every day is to sit (lie) on the sofa and release the fatigue of your body.

However, in many people's homes, the sofa has become the source of the most formaldehyde emissions, in addition to the man-made panels in the sofa, there is also a hard-hit area that is easy to be ignored, that is, sponge.

Sponge, as a padding for sofas, is originally formaldehyde-free. However, if the filling is a broken sponge glued together with a lot of glue, the formaldehyde content is definitely exceeded. It's scary to lie on it every day.

Therefore, when you buy a sofa, you must open the zipper to see if the sponge inside is whole or broken, if it is a broken sponge stuck together, then decisively do not buy, big brands of sofas are generally used whole sponge.

In addition, the quality of the sponge can also be judged from the following four aspects.

First: look at the density of the sponge.

Generally, the density of high-grade sofa cushion sponge is more than 30 kilograms of cubic meters, the density of cushion sponge is more than 25 kilograms of cubic meters, and the sofa cushion is best to be concave about 10 centimeters after sitting. If the density is not enough, there will be no elasticity when you sit on it, and the sitting feeling is very dead and uncomfortable at all.

Second: look at the sponge toughness.

A good sponge is very tough and does not tear easily. If there is a phenomenon of dropping a piece with a slight pull, it is definitely an inferior sponge. If you use it to fill the sofa cushions, it will collapse completely after a long time.

Third: look at appearances.

It can also be seen from the appearance of the sponge, the appearance of a good sponge is very delicate, and the pores are particularly small.

Third: see if it is fireproof.

Many people ignore the issue of fire prevention because they always feel that accidents don't happen. However, accidents often happen when you don't expect them, and indoor sofa fires abound, and the resulting damage to family members is also devastating.

Nowadays, many big brands of sofa sponges are fireproof sponges, even if the fabric or leather is on fire, the fireproof sponge can effectively block the spread of fire and reduce damage.

Whether it is fireproof or not, we can't judge with the naked eye, if the merchant says that their sponge is fireproof, please ask them to provide relevant proof. Or just ask for a sample, light it with a lighter, and if the flame goes out automatically, it proves to be a fireproof sponge.

Now that you know how important sponges are, don't just look at the frame when buying a sofa

Hello dear! Regarding the question of "whether the sponge mat contains formaldehyde", it can be made clear: **The sponge mat itself is formaldehyde-free**.

Sponge is a polymer material, and there are no formaldehyde-related components in its structure. However, sponge mats can harbor bacteria and mites because they are porous, so they need to be dried frequently to keep them clean.

At present, sponge mattresses and spring mattresses are the types of mattresses commonly used in modern times. Traditional sponges do not have a special sensitivity to temperature and cannot fully support the body shape curve; Sponge mattresses have relatively poor support, so they need to be flipped over every once in a while to avoid collapses in the sleeping area.

I have to say that there is no formaldehyde in the sponge. Formaldehyde is now mostly found in wood or glue. Sponge is actually a polymer material, although there is no formaldehyde in it, but people should use sponge reasonably in their daily life.

If the sponge is contaminated with other materials, it may also contain a certain amount of formaldehyde.

01 From the surface of the sponge, there are no harmful substances, and it belongs to a new type of material imported from abroad. However, what you need to pay attention to is that in the process of sponge production, it can be guessed that there will be some pungent gases produced by Nai Lueng.

02 Of course, this is also the reason why many friends cannot stay in the sponge factory for a long time, after all, when producing sponges, a large amount of gas is particularly pungent, and the release time is relatively long.

03 If people use sponges reasonably, under normal circumstances, sponges will not grow mites. After all, mites will also have corresponding conditions in the process of growth, such as humidity, food and so on.

04 The sponges we use in our daily lives are actually made of cellulose and foamed plastics. Perhaps because of the different materials of the sponge, there will be different needs when choosing, and we need to choose according to our own needs.
