What are the common environmentally friendly plasticizers in the PVC industry?

With the continuous improvement of global environmental awareness, all walks of life are striving to seek more environmentally friendly production methods and materials. In the PVC (polyvinyl chloride) industry, plasticizers are key additives to improve the flexibility of materials, and their environmental performance has attracted much attention. This article will discuss the common environmentally friendly plasticizers in the PVC industry, analyze their characteristics, applications and their significance to the green development of the industry.

1. The necessity of environmentally friendly plasticizers

Traditional PVC plasticizers such as phthalates, although they have excellent performance, their potential environmental toxicity and harm to human health are gradually revealed. Therefore, the research and development and application of environmentally friendly plasticizers have become an important topic for the green development of the PVC industry.

2. Common environmentally friendly plasticizers

Biodegradable plasticizers

Biodegradable plasticizers based on plant oils are highly efficient and biodegradable. They can directly replace traditional plasticizers and are suitable for food contact polymer materials, toys, medical devices, etc. This type of plasticizer is environmentally friendly and has no major harm even if it is accidentally ingested.

Citric acid ester plasticizers

Citrate ester plasticizers are synthesized with citric acid as raw material, are odorless and non-toxic, and can replace traditional phthalate plasticizers. They have been industrialized abroad and are widely used in cosmetics, daily necessities, toys and other fields.

Epoxidized plasticizers

Epoxidized plasticizers mainly include epoxidized soybean oil, epoxy acetyl linolenic acid methyl ester, etc. They have good heat resistance, cold resistance and migration resistance, and are suitable for refrigeration equipment plastic products, motor vehicle plastics, food packaging, etc.

Polyester plasticizers

Polyester plasticizers have excellent heat resistance, extraction resistance and migration resistance, and are one of the commonly used environmentally friendly plasticizers in the PVC industry. They are widely used in high-performance PVC products.

3. Application advantages of environmentally friendly plasticizers

Reduce environmental pollution: Environmentally friendly plasticizers are biodegradable, reducing pollution to soil and water sources.

Improve product safety: The characteristics of non-toxicity and odorlessness make PVC products safer and suitable for food, medical and other fields.

Meet regulatory requirements: With the increasingly stringent environmental regulations of various countries, the use of environmentally friendly plasticizers will help companies adapt to policy trends and avoid restrictions due to environmental issues.

IV. Outlook

With the continuous advancement of environmentally friendly plasticizer technology, its application in the PVC industry will become more and more extensive. Enterprises should seize the opportunity of green development, actively develop and promote environmentally friendly plasticizers, and contribute to the sustainable development of my country's PVC industry.

In short, the application of environmentally friendly plasticizers in the PVC industry is of great significance. In the long run, they will drive the entire industry to a greener and more environmentally friendly direction and create a better living environment for mankind.
