What is pearl cotton foam?
EPE foam or expanded polyethylene foam is one of the most widely used plastics in production. What is polyethylene foam? It is a thermoplastic resin, which means it can be melted by heating and cooling to form different shapes and objects.
What are the chemical and physical properties of EPE?
The physical and chemical properties of EPE foam give it desirable properties. It is because of these properties that this plastic has multiple applications in different industries such as EPE foam fillings, EPE foam pipes and EPE foam sheets.
Chemical properties of EPE foam
The chemical composition of expanded polyethylene is similar to most plastics in the form (C2H₄)nH2. EPE is usually white unless dyes or other colored pigments are added during the melting process.
EPE foam is also known as bead board in the plastics industry. It is a closed-cell foam that can take up more volume and be lightweight.
EPE pearl cotton physical properties
EPE foam is a harmless plastic with no taste or smell.
It is a very popular material for merchandise packaging due to its light weight and flexibility. It has the ability to absorb shock and provide good cushioning for delicate objects.
EPE has a high weight-to-strength ratio and high heat resistance. Due to the high temperature range of EPE foam, it can be heated and melted multiple times and reshaped into other new objects.
EPE foam is resistant to water, oil and many chemicals. It is also a very good insulating material. Depending on its application or purpose, EPE comes in different densities.
Can EPE pearl cotton be recycled?
Yes! This is probably one of the most important properties of foamed polyethylene because of its huge potential impact on the environment.
Expanded polyethylene foam can be melted many times and reshaped into various shapes. This is due to its high heat-resistant properties which allow it to maintain its chemical structure even when exposed to high temperatures and turned into molten plastic.
This is a very important property of the EPE material, making it reusable and recyclable, reducing the amount of plastic in the environment.
However, the number of companies offering recycled EPE is very limited, resulting in very low recycling rates worldwide. Melting and recycling EPE or compacted plastic is critical to prevent EPE waste from being burned or added to landfills.
The most common recycling methods are reusing EPE or bonding and grinding expanded polyethylene. Recycled EPE can be used as packaging material or as underlay for great room carpet.
What are the advantages of EPE pearl cotton?
1. Super shock absorption performance
The closed-cell structure of EPE foam enables it to withstand and absorb large amounts of impact or pressure and provides good cushioning for the objects it covers.
2. Extremely flexible
EPE foam is a very flexible material compared to other forms of foam. Therefore, EPE can provide maximum protection for oddly shaped objects.
3. Chemical resistance
EPE foam is highly resistant to strong corrosive chemicals such as solvents, acids and bases. This makes it suitable for providing barriers or shields for extra protection when storing and handling these chemicals.
4. Get back into shape easily
Another advantage of expanded polyethylene is that it quickly returns to its original shape after the source of stress or shock is removed. It cannot be broken, broken, broken or crushed.
5. Insulation properties
EPE foam has a very low thermal conductivity and therefore has an optimal thermal insulation effect.
6. Waterproof/Moistureproof
The chemical structure of expanded polyethylene foam makes it virtually impermeable. Therefore, EPE does not absorb or let water pass through. Therefore it is used as a waterproof protection for the material.
7. Antistatic
Some forms of EPE are highly antistatic, so they don't attract dust and other tiny particles to their surface.
8. Non-toxic and food safe
EPE foam is non-toxic, so it can be used in food packaging. It is also resistant to the growth of microorganisms and fungi on its surface. It is tasteless.
9. Aesthetics
EPE foam can be dyed in a variety of colours, allowing for color coding or purely aesthetic applications.
10. Easy to operate
EPE foam is fairly easy to work with. It is easily cut, molded, shaped and glued to other objects or itself. It can be easily formed into various objects without the use of expensive equipment or molds.
11. Operating temperature range
EPE foam can be used in a temperature range of 40 to 70 degrees without affecting its structure or any performance, so it is very suitable for various applications requiring thermal or electrical insulation.
12. Extremely light weight
EPE foam, while fairly tough, is very lightweight, making it easy to transport and handle. Due to this property, it can be used in a variety of applications.
What are the applications of EPE?
Expanded polyethylene can be used in a variety of applications such as the following:
under construction:
EPE can be used in many applications in the construction sector, such as caulking, waterproofing, etc.
damping:
EPE foam can be used to protect fragile and fragile items such as glass and glassware, scientific instruments, mechanical precision parts, marble, granite and other easily scratched materials.
Buoyancy application:
EPE is used in the manufacture of life jackets and other flotation devices.
insulation:
Foamed polyethylene is widely used for insulation of air conditioners, pipes, heaters, etc.
Sports:
EPE is used to make sports mats, yoga mats, shin guards, thigh guards, etc.
