How many grades of hardness are there for EPE pearl cotton?

The hardness of EPE pearl cotton is related to the density of the material, generally the greater the density, the higher the hardness, the density is related to the manufacturer, there are many grades, depending on the demand to choose the corresponding density. With the same density, the performance of imported materials is superior to that of domestic materials. There are no hardness ratings.

Polyethylene foam is a non-cross-linked closed-cell structure, also known as EPE pearl cotton, which is a new type of environmentally friendly packaging material. It is made of low-density polyethylene.

The fat is physically foamed to produce a myriad of individual bubbles.

Hope it helps.

8 categories.

Basic characteristics of technical parameters:

30-40 times higher foam molded products, light weight, and a certain degree of robustness.

Softness and cushioning are good.

The thermal conductivity is very low and the thermal insulation is excellent.

Foam material with independent bubbles, waterproof material with almost no water absorption.

High foaming and excellent waterproofing make it very buoyant.

It is not corrosive and corrosion-resistant material of various drugs.

Product Features:EPE pearl cotton coating machine is a coating machine developed for the need to coat hot melt on a large area of pearl cotton (sponge, EVA) (especially some thin sheets that are difficult to operate manually), which is easy to use and has high efficiency. It is especially suitable for deep processing (assembly, assembly, lamination, gluing, compounding) in EPE pearl cotton industry.

The gluing design is based on the needs of the product and the different materials of the glue, the thickness of the glue can be adjusted, it is characterized by fully enclosed, not easy to leak glue, easy to clean up the glue; The external design of the roller bearing has a long life, low failure, and can be overhauled without stopping when the glue is melted, without affecting the production.

It completely solves the phenomenon of temperature overshoot, does not yellow glue, has shovel resistance, high temperature resistance and does not fall off the coating, and does not change color and black for many years; More importantly, it has uniform coating, high efficiency, and can reduce a lot of labor input.

Generally speaking, domestic pearl cotton is graded according to density, the current low density on the market is 16-18kg m 3, the density is about 20, and the customer requirements are high at about 22-25kg, of course, it depends on customer requirements, if the requirements are higher, you can do 28k-30kg, if you are more demanding, you generally choose a foamed pearl cotton, there are not many domestic manufacturers of this material, the density can be divided into pounds, pounds, pounds, 4 pounds, 6 pounds, 9 pounds, If you have more questions, you can contact Shanghai Ebillon packaging products****, search for this company on the Internet, this company is still very professional.

The hardness is related to the density of the material, and the density of imported materials is harder than that of domestic materials. Generally, the higher the density, the higher the hardness.

1. **Above: Because of the density, EPE pearl cotton of the same volume is heavier. This determines that it is more expensive than foam. Generally, it is about 3 times that of foam.

2. Environmental protection: EPE pearl cotton is an environmentally friendly material, while foam (EPS) is not environmentally friendly and not easy. It has been banned abroad since 2004. In 2007, China also banned the use of foam on disposable tableware.

3. Attributes: EPE pearl cotton is soft and has very good rebound; The foam is hard and rebounds slowly.

EPE pearl cotton is an environmentally friendly foaming material with cushioning and anti-shock ability, which is soft, light and elastic, and can absorb and disperse external impact force by bending, overcoming the shortcomings of ordinary styrofoam cover that are fragile, deformed and poorly recovered. At the same time, EPE pearl cotton has a series of superior characteristics such as heat preservation, moisture resistance, sound insulation, friction resistance, aging resistance, corrosion resistance, etc. The special material EPE pearl cotton is added, which has remarkable anti-static properties.

It is also an environmentally friendly material that can be **. Guanghong vertical is widely used in construction, mechanical and electrical engineering, furniture, household appliances, instrumentation, craft gifts, wood products, glass ceramics, carpet sandwich, travel luggage, precision parts packaging and other major products of internal and external packaging.

EPE is not made from natural cotton, but is composed of numerous individual bubbles produced by physical foaming of low-density polyethylene ester.

Pearl cotton: ordinary pearl cotton, wax-free pearl cotton, extra flat pearl cotton, encrypted pearl cotton, encrypted hardened pearl cotton, anti-static pearl cotton, PO coated pearl cotton, PE coated pearl cotton, aluminum foil pearl cotton, color film laminated pearl cotton, pearl cotton, PS board (pearl board), KT board (advertising board), fireproof pearl cotton, pearl cotton bridge.

Special-shaped materials of pearl cotton: tube-shaped, rod-shaped, L-shaped, U-shaped and various special-shaped materials, pearl cotton components, pearl cotton can also be processed into pearl cotton bags of various sizes after lamination.

It is made up of low-density polyethylene grease that is physically foamed to produce numerous individual bubbles. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed and have poor recovery. It has many advantages such as water and moisture resistance, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, etc., and also has good chemical resistance.

It is an ideal alternative to traditional packaging materials. It is widely used in electronic appliances, instrumentation, computers, audio, medical equipment, industrial control cases, lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture, wine and gift packaging, hardware products, toys, melons and fruits, leather shoes inner packaging, daily necessities and other product packaging. When antistatic agents and flame retardants are added, it shows its excellent performance

EPE EPE is also widely used in the elastic lining of handbags and bags, industrial production of sound insulation, heat insulation, agricultural insulation materials, aquaculture floating equipment, sports equipment protective pads, water work life-saving equipment, home and hotel floor decoration, liners and so on. Its pipes are widely used in air conditioning, strollers, children's toys, furniture and other industries.

EPE and adhesive products for various fabrics are good interior materials for all kinds of vehicles and homes.

The pearl cotton foaming machine is dedicated to the production of EPE materials, which are made of polyethylene plastic particles LDPE, which are heated, melted, extruded, catalyzed, and foamed to form pearl cotton sheets, rods, pipes, U profiles, V profiles, fruit nets and other plastic materials. The material is characterized by sound insulation, heat insulation, impact resistance, friction resistance, shock resistance, waterproof, anti-corrosion, moisture-proof, anti-deformation, non-toxic, no odor, elasticity and some characteristics. It can be made into sheet materials, and can also be made into various packaging materials and filling materials by compounding and laminating, which is widely used in electronics, electrical appliances, craft products, ceramic products, lighting, computer products, furniture and other packaging.

Due to its special advantages, pearl cotton not only does not pollute the environment, but also can be used repeatedly without pollutant emissions.

EPE pearl cotton is widely used in the packaging industry, everyone knows, and the EPE pearl cotton that can be seen everywhere in life also needs to have relevant selection methods, otherwise it will be difficult for us to choose in the face of many choices.

2. Choose the most reasonable materials.
