PEVA is a high-performance thermoplastic that has many advantages over PVC (polyvinyl chloride), especially in terms of environmental protection, safety, physical properties and processing performance. The following are the main advantages of PEVA materials over PVC:
1. More environmentally friendly
PEVA: does not contain chlorine and harmful plasticizers such as phthalates, so it does not release toxic gases during the production process and has less impact on the environment and human health. It is a material that meets environmental standards and is suitable for food contact, medical supplies, and children's products.
PVC: usually contains chlorine, and a large amount of plasticizers (such as dibutyl phthalate) need to be added during the production process. These substances may release harmful gases at high temperatures, causing potential harm to human health and the environment.
2. Higher safety
PEVA: non-toxic and odorless, does not contain harmful chemicals, and is suitable for direct contact with skin or food. For example, PEVA film can be used to make food packaging bags, baby products, etc.
PVC: Because it contains chlorine and plasticizers, it may irritate the human body. Long-term contact may cause allergies or respiratory problems, so it is restricted in some applications.
3. Better low temperature resistance
PEVA: It can still maintain good flexibility and ductility in low temperature environments, and it is not easy to become brittle or crack. This makes it more advantageous when used in cold areas or in winter.
PVC: It is easy to harden or even crack at low temperatures, affecting its performance and life.
4. Lighter weight
PEVA: It has a lower density and is much lighter than PVC, so the products made are lighter, easy to carry and use.
PVC: Due to its high density, the products made are relatively heavy and are not suitable for application scenarios that require lightweight design.
5. Better recyclability
PEVA: As a thermoplastic, PEVA material is easy to recycle and reuse, and can be reprocessed into new products, which helps reduce the generation of plastic waste.
PVC: Although it can also be recycled, due to its complex chemical structure, it is difficult to recycle, and the performance of the recycled material is significantly reduced, which limits its reuse value.
6. Better processing performance
PEVA: It has good processing performance and can be processed into films of various shapes and thicknesses by blow molding, injection molding, calendering and other methods, which is suitable for a variety of industrial and consumer products.
PVC: Although it can also be processed by a variety of methods, it is easy to produce static electricity, adhesion and other problems during its processing, which increases the difficulty of production.
7. Good waterproofness
PEVA: It has excellent waterproof performance and can effectively prevent water penetration. It is suitable for making raincoats, umbrellas, waterproof packaging and other products.
PVC: Although it also has good waterproof performance, its surface is prone to aging and cracking, which affects the long-term use effect.
8. Biodegradability
PEVA: It can be partially biodegraded under certain conditions, which helps to reduce long-term pollution to the environment.
PVC: It is almost not degradable, exists in the environment for a long time, and is easy to cause white pollution.
What are the advantages of using PEVA materials in umbrellas?
PEVA materials are widely used in umbrella manufacturing due to their excellent physical properties and environmental protection characteristics. The following are the specific advantages of PEVA materials in umbrellas:
1. Excellent waterproof performance
PEVA materials have good hydrophobicity and waterproofness, which can effectively prevent rainwater penetration and ensure the use effect of umbrellas in humid environments. Even in heavy rain, the umbrella surface can be kept dry to protect users from getting wet.
2. Corrosion resistance
PEVA materials have good corrosion resistance to chemicals such as acids, alkalis, and salts, and are suitable for use in various harsh environments, such as the seaside, industrial areas, etc., to extend the service life of umbrellas.
3. Good flexibility
PEVA materials have good flexibility and elasticity, which can adapt to the frequent bending and stretching of umbrellas during use, and improve the comfort and durability of use. Even in strong winds or heavy rain, the umbrella surface can be kept stable and not easily deformed.
4. Environmentally friendly and non-toxic
PEVA materials are non-toxic and odorless, meet environmental protection standards, and are suitable for daily use, especially for children and sensitive people. It does not release harmful gases and does not pollute the environment.
5. Not easy to age, fade, or deform
PEVA materials can still maintain good appearance and performance after long-term use, and are not easy to age, fade, or deform due to ultraviolet radiation, temperature changes, or humidity. This allows the umbrella to remain beautiful and functional after repeated use.
6. Diverse surface treatments
PEVA materials can achieve a cloth texture effect through embossing or special printing technology, giving the umbrella surface a texture and touch similar to textiles, enhancing the product's beauty and fashion sense. At the same time, this texture treatment can also enhance the anti-slip properties of the umbrella surface and improve grip comfort.
7. Lightweight and easy to carry
Due to the low density of PEVA materials, the overall weight of the umbrella is light, which is easy to carry and use, especially suitable for outdoor activities, travel, or daily commuting.
8. Long service life
PEVA materials have a long service life under normal use conditions, and can withstand multiple folding, unfolding, and rain scouring, reducing the frequency of replacement and improving cost performance.
