Polyethylene foamed cotton long and short cross-linked closed-cell structure, also known as EPE pearl cotton, is a new environmentally friendly packaging material. It consists of low density polyethylene glycol by physical foaming to produce a myriad of independent bubbles. It overcomes the shortcomings of common styrofoam, such as fragility, deformation and poor recovery. It has many advantages such as water-proof, moisture-proof, shock-proof, sound-proof, heat-insulating, good plasticity, toughness, reincarnation, environmental protection, strong impact resistance, etc. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials.

 

Chinese name: pearl cotton

 

Abbreviation: EPE

 

Aliases: Polyethylene foamed cotton

 

Features: non-crosslinked closed cell structure

 

Application:

 

Widely used in car seat cushions, pillows, electronic appliances, instrumentation, computers, audio, medical equipment, industrial control chassis, hardware lighting, crafts, glass, ceramics, home appliances, painting, furniture furniture, alcohol and resin and other high-end fragile gifts Packaging, hardware, toys, fruits, inner packaging of leather shoes, daily necessities and other products packaging, as well as express packaging. Adding color antistatic agents and flame retardants, it also shows its excellent performance. Not only does it look beautiful, but it also effectively prevents static electricity and burning.

 

       Adhesive articles of EPE and various fabrics are good interior finish materials for a variety of vehicles and homes. The composite product of EPE pearl cotton and aluminum foil or aluminized film has excellent anti-infrared ultraviolet light capability, and is a must for some chemical equipment refrigerators and camping equipment. Its pipes are widely used in air conditioners, baby carriages, children's toys, furniture, plumbing and other industries.

 

        Because it has special strengths, it not only does not pollute the environment, but also can be recycled and reused. Therefore, EPE pearl cotton foaming material is a new type of material that never fades. With the advancement of time and the continuous development and application of products, EPE pearl cotton foam materials will be more widely used in packaging and filling materials.

 

At present, the production of EPE pearl cotton foaming material has been developed in the Pearl River Delta. The use of this material has become more common in all walks of life, and the enterprises that produce and use the material have obtained good economic benefits, and the results are very obvious. Now the production of this material is gradually expanding to Zhejiang, Shanghai, Shandong and other provinces and cities. However, in fact, enterprises that have already invested in production lines are far from being able to meet the needs of various industries in the industry. Moreover, there are still many provinces and cities in the vacant area in the country, and there is an urgent need for this new material to fill the needs of packaging and filling industries.

 

       Because EPE [1] EPE foam material is a new type of environmentally friendly packaging and filling materials. Its superior characteristics are becoming more and more familiar, so its use will continue to expand and stand out. Especially in the packaging and other industrial materials, it is better than the traditional material machine, the cost is lower, the grade is higher, the appearance is more generous, and the effect is better. In addition, it is even more broad in the field of agricultural and sideline products packaging materials. At the same time, EPE pearl cotton foam sheet can also be further processed. It only needs to prepare pearl cotton laminating machine and laminating machine. It can cover HDPE film, aluminized film, plastic coated paper, plastic coated cloth, etc. on the surface of EPE sheet. After the filming of the EPE sheet, not only the mechanical strength is improved, but also the various functions and printing of various patterns and characters, and the promotion of product promotion can be improved. Moreover, the composite sheet can be widely applied to inner liners such as box linings, life jackets, heat insulation, moisture-proof tents, etc., and the economic benefits doubled.

 

       In addition, EPS (expanded polystyrene) packaging products cannot be recycled after use, causing white pollution and being banned internationally. In 1998, Europe and the United States and other countries promulgated any products that banned EPS packaging. In 1999, China issued a partial ban on EPS fast food boxes, such as railways. Therefore, EPE pearl cotton packaging products will completely replace EPS packaging materials, which will soon occupy the packaging market and may replace Packaging materials such as paper, corrugated board, etc., and the shape is also more beautiful than any packaging material.

Special fiber

 

It is a three-dimensional crimped hollow fiber, which is processed into a ball-shaped cotton by special ball-forming technology. The inside of the cotton ball is hollow, and has a large ventilation space, which is more warm and breathable. Moreover, after the product is quilted, it will automatically expand, even if it is machine washed, it will not be deformed. Mostly used for pillows.

 

Generally, three-dimensional 7D (thickness) * 51 (length) is used to make pearl cotton.

 

Foaming shrinking agent-monoglyceride

 

In the production process of pearl cotton, if the finished product without the addition of monoglyceride will shrink and soften, it is necessary to add the anti-shrinking agent molecular distillation monoglyceride in the production process [2].

 

Molecular distillation monoglyceride is a high-quality and high-efficiency additive, which has the functions of no chaos, foaming, anti-shrinkage, lubrication, antistatic, auxiliary modification and anti-fogging. It is used in daily chemical, plastic, packaging and It is widely used in cosmetics and other industries.

 

Molecularly distilled monoglyceride is an ideal co-blowing agent and anti-shrinking agent. In order to meet the needs of environmental protection, Freon-based foaming agents will gradually be eliminated. It can be used as a foaming agent for high-foamed polyethylene and polystyrene, and it can be used together with a foaming agent such as butane, and has very good effects. Moreover, the surface of the plastic foamed product using the molecularly distilled monoglyceride is very smooth and bright, and does not cause shrinkage.

 

Molecular Distillation Monoglyceride is an excellent internal lubricant that reduces the friction between polymer molecules, thereby reducing the viscosity of the polymer melt and improving its activity. It has good compatibility with resin, easy to disperse, and is suitable for the advantages of transparent products. Its antistatic effect is very obvious, which can reduce the electrostatic formation and accumulation of plastic products, reduce the adsorption of dust on plastic products, and maintain the transparency and clean appearance of the products.
