Summary: Eco-friendly plasticizers are a new type of plasticizer, characterized by being non-toxic, non-carcinogenic, and environmentally friendly. Eco-friendly plasticizers are used in plastic products, while traditional plasticizers in plastic products face serious safety challenges. The development of new types of eco-friendly plasticizers is urgent, and plastic products using eco-friendly plasticizers will dominate the international market.

Eco-friendly plasticizers are a new type of plasticizer, characterized by being non-toxic, non-carcinogenic, and environmentally friendly. Eco-friendly plasticizers are used in plastic products, while traditional plasticizers in plastic products face serious safety challenges. The development of new eco-friendly plasticizers is urgent, and plastic products using eco-friendly plasticizers will dominate the international market. These advantages are inseparable from the outstanding characteristics of eco-friendly plasticizers:

1. Volatility

The biggest difference between plasticizers and solvents is volatility. Solvents generally have high volatility and therefore cannot be used as plasticizers. The loss of flexibility in soft polyvinyl chloride (PVC) products due to plasticizer volatilization and dissipation is a major problem in practical applications. The volatility of plasticizers in soft PVC is related to the speed at which the plasticizer diffuses from the inside to the surface of the product and the effective vapor pressure of the plasticizer on the surface of the product. Under normal conditions, the latter effect is dominant. (Eco-friendly crosslinking agents, eco-friendly PVC crosslinking agents, eco-friendly plasticizers)

By comparing the temperature obtained from the individual vapor pressure of the plasticizer (0.05 μHg) and the heat resistance temperature obtained from the aging properties of the product, it is clear that the volatility of the plasticizer is closely related to the heat resistance and light resistance of the plasticizer. The maximum allowable operating temperature (i.e., continuous use temperature) obtained from the vapor pressure of the plasticizer (0.05 μHg) shows that dioctyl phthalate can be used continuously at 68°C, while di(2-ethylhexyl) phthalate and diisodecyl phthalate can be used continuously at 80°C and 92°C, respectively. Tests show that the volatility of petroleum sulfonate is superior to that of dioctyl phthalate. (Eco-friendly crosslinking agents, eco-friendly PVC crosslinking agents, eco-friendly plasticizers)

2. Migration

The migration of plasticizers to substances in contact with soft polyvinyl chloride is also important in practical applications. Both migration and volatility involve the diffusion of plasticizers from the inside to the surface of the polyvinyl chloride product. Volatility refers to the evaporation of plasticizers from the surface, while migration refers to the diffusion of plasticizers to the contact layer. Therefore, migration consists of two processes: diffusion of plasticizers within the product and diffusion within the contact layer.

3. Oil Resistance

In oil, plasticizer extraction is related to the plasticizer's solvation ability for the resin and its oil resistance. Usually, the diffusion rates of plasticizers are not significantly different, so oil resistance mainly depends on the plasticizer's solvation ability for the resin. Generally speaking, plasticizers with a smaller interaction constant with the resin, i.e., those with a stronger solvation ability for the resin, have better oil resistance, and vice versa.

4. Electrical Insulation

The electrical insulation of soft polyvinyl chloride plastics largely depends on the type, properties, and amount of plasticizer used. High-polarity plasticizers, because they can fix the polymer main chain in polarized positions, have higher electrical insulation properties. Therefore, chlorinated paraffin, phthalates, petroleum sulfonates, and phosphates have better electrical insulation properties. For plasticizers with high electrical insulation requirements, the content of ionic impurities in the plasticizer should be minimized.

Eco-friendly plasticizers have a vast international market. With technological advancements, some traditional plasticizers may be replaced by new eco-friendly plasticizers. The research and development of new eco-friendly plasticizers with advantages such as harmlessness, low cost, and good auxiliary effects as substitute materials is a key aspect of the current development of the plastics industry.
