• Performance Characteristics
  • High - temperature Resistance: It can be used at temperatures above 180℃ for a long time, with good thermal stability.
  • Low Volatility: Its volatility is significantly lower than that of traditional phthalate plasticizers, which can reduce the migration of plasticizers and ensure the stable performance of plastic products.
  • Good Durability: It can improve the mechanical strength and flexibility of plastic products, and extend the service life of products.
  • Environmental Protection and Safety: It is non - toxic and meets the safety standards of food - contact materials in many countries. It belongs to an environmentally friendly plasticizer.
• Preparation Method: Using trimellitic anhydride as the raw material, adding n - octanol in the presence of a catalyst such as p - toluenesulfonic acid or sulfuric acid, and preparing the finished product through a series of processes such as full - reaction, distillation, washing and dehydration.
• Application Fields
  • Medical Devices: It can be used to manufacture catheters, blood bags, etc., meeting the biocompatibility requirements.
  • Food Packaging: It is often used in the production of food bags and film materials, with good barrier properties and no migration pollution.
  • Electronics and Electrical Appliances: It is suitable for the sheaths of high - temperature - resistant wires and cables, ensuring electrical safety and long - term service life.
  • Industrial Film Materials and Films: It can improve the flexibility and durability of materials, and enhance product quality.
• Packaging and Storage: Usually packed in 200kg steel drums. It should be stored in a cool, dry and well - ventilated environment, kept away from oxidants and other chemicals, and avoided from high temperatures and direct sunlight.
