PE physical foam breathable liner

Breathability liner is composed of PE foam liner and macromolecule breathability film.The function is can breathable and non leakage.

PE (polyethylene) foam gaskets are widely used in a variety of fields, including but not limited to:

1. Packaging industry: used to wrap and protect fragile items such as glass, ceramics and electronic products. 

2. Sports equipment: used as sports protective gear or protective pads, such as helmet lining and knee pads. 

3. Automotive industry: Used in automotive interior, sound insulation materials and fenders. Building and construction: For insulation, sound absorption, sealing and shock absorption. 

4. Medical equipment: Used for medical equipment packaging and protective pads. Electronics industry: Used for lining, filling and protection of electronic products. 

5. Agriculture: Used for shock absorption, protection and packaging of agricultural equipment.

PE foam gaskets usually have the following characteristics: Light weight: PE foam gaskets are made of polyethylene material, so they are light in weight. Durability: Good tear resistance and wear resistance. Good buffer performance: can provide good buffer protection, can reduce the impact of external impact on the packaging of goods. Thermal insulation: PE foam gasket has a certain thermal insulation performance, suitable for packaging items that need to maintain temperature. Waterproof and moisture-proof: Under normal circumstances, PE foam gasket has a certain waterproof and moisture-proof performance, which can protect the packaged items from moisture. These characteristics make PE foam gaskets widely used in packaging and protection fields.

The difference between EPE and PE is as follows:

1. PE material. PE is a foam material, which is a very environmentally friendly crawling mat material. At the same time, the PE material crawling mat is odorless.

2. EPE material. EPE material crawling pad is also called pearl cotton crawling pad. It has very strong thermal insulation, sound insulation, heat insulation and other functions, which can provide a very comprehensive protection for the baby. This material has a very good cushioning effect.

PE and EPE are two different plastic materials, the main difference between them is the raw material and the manufacturing process.

PE (Polyethylene), short for polyethylene, is a common plastic material with the following characteristics:

Transparency and flexibility

Non-toxic and low price

Good processing properties, including molding shrinkage and ease of processing

Chemical resistance and corrosion resistance

Low water absorption, no special drying treatment is required

Processing temperatures range widely, usually between 180 and 220 degrees Celsius

Crystallinity and density can be adjusted as needed

EPE (Expanded Polyethylene), also known as pearl cotton, is a polyethylene material that has been treated with physical foaming. Its non-crosslinked closed cell structure gives it the following properties:

High strength cushioning and seismic capability

Flexibility, light weight and good elasticity

Able to absorb and disperse external impact forces Heat preservation, moisture resistance, heat insulation, sound insulation and anti-friction properties

Resistance to aging and corrosion

It can be extruded or foamed to form sheets, sheets or tubes

After proper processing, such as stamping, cutting and bonding molding, it can be used to make packaging materials and other applications

In summary, PE is a polyethylene material that has not been foamed, while EPE is a polyethylene foamed material produced by a physical foaming process, which has unique buffering and protection characteristics.

Physical foaming and chemical foaming are two different plastic foaming processes, and their differences and characteristics are as follows:

- Physical foaming is the use of physical principles to foam, such as in the plastic into the gas or liquid, and then make it expand or vaporize. Physical blowing agent is generally non-toxic, odorless, non-corrosive, non-burning, good thermal stability of gas or liquid, such as carbon dioxide, nitrogen, low boiling point hydrocarbons. The foaming material prepared by physical foaming method is pure, safe, environmentally friendly, and has good sound insulation, heat insulation, flame retardant and other properties, but it requires special equipment and high pressure conditions, and the technology is difficult.

- Chemical foaming is the use of specially added chemical foaming agent thermal decomposition or chemical reaction between raw material components to produce gas, so that the plastic melt filled with the method of bubble holes. Chemical blowing agents are generally organic or inorganic compounds that can decompose and release gas at a certain temperature, such as azodicarbonamide, sodium bicarbonate, ammonium carbonate, etc. The foaming material prepared by chemical foaming method has low cost and mature process, but it may produce some toxic, smelly and colored by-products, which have a certain impact on the environment and human health.
