Foam and memory foam are by far the most common mattress foam fillings. cellulose sponge manufacturerAlthough both are sponge fillers, they have their own unique characteristics. The following details the characteristics of the two:
Sponge:
Sponge is also known as is a polyurethane foam composite material, wholesale Konjac spongeour country commonly used sponge by lignocellulose nanofibers or foamed plastic polymers can be made.
Sponge has a porous honeycomb structure, so it has good flexibility, water absorption and other characteristics.
Classification of sponge
It is generally believed that the higher the density of a sponge, the harder it is, natural luffa spongebut this is not accurate. Generally speaking, the softness and hardness of sponge has little to do with the density, mainly through the adjustment of the formula to change its hardness, the same density of sponge can make different hardness.
Frequently asked questions about foam mattresses.
1. Yellowing of sponge
Because the sponge itself reacts to release heat in the processing process can not be quickly released, the core of the sponge becomes yellow.
Secondly, long-term exposure to ultraviolet radiation can also lead to oxidative yellowing of the sponge.
2. Mattresses just open the student will have a different flavor
Because the sponge is a polyurethane product, the new sponge mattress itself will have a little sponge flavor, especially when the compressed bag is opened.
But this odor is almost harmless to the human body.
Newly purchased sponge mattresses are recommended to be ventilated for 48 hours before use.
3. Sponge mattress collapse
Generally in this case, the bubble is good, the size carries on evenly, good resistance, good resilience of the quality development of sponge mattress is not can easily happen to collapse.
Memory foam
Memory foam, also known as slow rebound sponge, is also a type of sponge. The sponge consists of an open structure of molecules that can move under external forces and disperse them to accommodate the entire contact surface.
In addition to the basic characteristics of a sponge, memory foam is also characterized by pressure dispersion and comfort.
Memory foam is categorized into temperature-sensitive memory foam and non-temperature-sensitive memory foam.
Warm-sensitive memory foam is called warm-sensitive memory foam because its softness and hardness change significantly with temperature.
When the temperature is lower than 10 degrees, the warm memory foam will become hard, and
At temperatures ≤ 0 degrees we are hard as a rock.
So in general, I personally do not recommend that our friends in the north buy warm memory foam bedding.
Non-thermal memory foam, also known as gas-sensitive cotton, is for the characteristics and shortcomings of warm memory foam.
The hardness of non-thermal memory foam does not change with the temperature and the difference is obvious, so that people can experience the comfort of memory foam in any environment.
Gas sensing cotton due to our special bubble hole structure, the feel will be more need to soft and comfortable, also has the ability to strong moisture absorption processing function, to a great extent, can save the cool feeling of the surface of the sponge city.
Small point: memory foam rebound time and density is very important, rebound speed 3-5 seconds is good, the higher the density the more expensive. The mattress with high density of the product can support the inside of the knees, waist, back and neck with enough fit and support.
Memory foam mattresses can fit the human body curves of people with different weights, allowing the body to sleep infinitely close to zero pressure, and improving the effect of healthy sleep.
