Does anyone know about Styrofoam s materials? What does Styrofoam mean

Foam. Styrofoam is a material formed by high-temperature foaming of polystyrene and foaming agent, commonly called "styrofoam". Styrofoam is also called porous plastic.

It is a plastic made of resin as the main raw material and has countless micropores inside. It has the advantages of light weight, heat insulation, sound absorption, shockproof, moisture resistance, corrosion resistance and so on.

Foam can be divided into soft, rigid and semi-rigid foam in between according to its flexibility.

Rigid foam can be used as thermal insulation materials and sound insulation materials, insulation materials for pipes and containers, floating materials and shock-absorbing packaging materials; Flexible foam is mainly used as a padding material, foam artificial leather, etc.

Styrofoam is a material formed by high-temperature foaming of polystyrene (PS) and foaming agent, usually called "foam". When heated and formed, according to the different foaming ratios, it can be made into disposable tableware, fresh trays, instant noodle bowls, hamburger boxes and other containers. It can also be used as a shockproof packaging pad, which is light and strong, but not environmentally friendly, and is gradually turning to paper packaging.

When you open the new large appliance box, the shockproof inside is it.

Polystyrene is a plastic raw material refined from petroleum, composed of carbon and hydrogen, with the chemical formula (C8H8)N, which can be made into egg cartons, Yakult bottles, video cassettes and other plastic products.

Styrofoam, as it is called in Taiwan Province, refers to "plastic foam". The most common thing is to pack seafood and fruit boxes, while in the mainland, everyone calls them plastic boxes, and Styrofoam is a saying that can only be found in Taiwan.

Bubbles:

Foam is a number of small bubbles that come together. A system of dispersions formed by the dispersion of insoluble gases in liquids or molten solids. By extension, the bubble is a metaphor for the apparently prosperous and prosperous elements of a thing, but in fact it is vain and unreal.

For example, bubble economy refers to an economic phenomenon that is superficially prosperous due to extremely active speculation and trading, and the market of finance, real estate, etc., is greatly detached from the actual value. To put it simply, it is **out of value.

It is a homonym for an English phrase and is commonly used in Taiwan.

Polystyrene foam.

Styrofoam refers to:Foam. It is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastics, which has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and the dielectric properties are better than those of matrix resins, and they are widely used.

Almost all kinds of plastics can be made into foams, and foam molding has become an important area in plastics processing.

Features:

1. The bulk density is very low, which can reduce the weight of packaging and reduce transportation costs.

2. It has an absorbent sail with excellent shock and vibration energy, which is used to cushion and shockproof packaging, which can greatly reduce the damage of the product.

3. It has strong adaptability to changes in temperature and humidity, and can meet the requirements of the general packaging situation of hail.

4. Low water absorption, low hygroscopicity, good chemical stability, it will not corrode the contents, and has strong resistance to acids, alkalis and other chemicals.

5. Thermal conductivity.

Low, can be used for thermal insulation packaging, such as ice cream cups, fast food containers and insulated fish boxes.

The above content refers to Encyclopedia — Styrofoam.

Styrofoam is Styrofoam.

It is dispersed in solids by a large number of gas pores.

Styrofoam belongs to a kind of foam plastic, which is rarely widely used in life, and many manufacturers will use such a material, I have seen such a material in Shenzhen Sanguyuan before, which is very practical.

Polystyrene is a material formed by high-temperature foaming, commonly called"Foam. ", used as a shockproof packaging pad, light weight, sturdy, but not environmentally friendly, gradually turning to paper packaging, you open the newly bought large household appliance packaging box, inside the shockproof is it.

Styrofoam generally refers to foam, which is a type of polymer material formed by a large number of gas microporous beams dispersed in solid plastics. Polysol is called foam in mainland China, styrofoam in Hong Kong, styrofoam in Taiwan, and polystyrene EPS in plastic. Styrofoam is an excellent shockproof packaging material, which is inexpensive and widely used, with properties and characteristics such as heat insulation, sound insulation, shock resistance, light weight cushioning, and easy molding.

Styrofoam is covered with numerous micropores that are connected or disconnected to each other, resulting in a significant reduction in apparent density. According to its cell structure, it can be divided into closed-cell, open-cell and reticulated foam source socks. Closed-cell styrofoam has almost no connected cells.

Open-cell styrofoam has almost all the cells connected. Foam with almost no cell walls is called mesh foam. According to the density of foam, it can be divided into low foam, medium foam and high foam foam.

EPS (Styrofoam) cutting is fast, its size, specification, shape, can be produced and designed according to the specific requirements of customers, without the cost of molding, can be changed at any time according to customer products, to meet the different requirements and special design of customers' various hail species. It can be processed and formed, commonly used lining, special cutting plate, corner protection, edge protection, etc. Mechanism EPS (Styrofoam) requires mold opening, which is suitable for all kinds of packaging with high demand and complex shapes.

Applications: office furniture, glass products, instrumentation, stone, gift boxes, handicrafts, construction engineering and so on. Styrofoam is vacuum-formed in white, a material that has a low degree of degradability and a great impact on the environment. It is generally prohibited in the Japanese and European markets.
