Environmentally friendly PVC plasticizers Research

Polyvinyl chloride (PVC) applied mainly plasticizers phthalates, accounting for the amount of the plasticizer is about 80%. Phthalate plasticizers have good elastic properties of plasticized products, outstanding durability, especially in soft PVC products (soft leather, toys, etc.) fields in the past few decades has been widely used. In recent years, people with health concerns and the traditional PVC phthalate plasticizers conduct research found that phthalate plasticizers may produce toxic effects on the human body, and even cancer, especially for infants and growth and development of children greater impact.
People are increasingly considering the development of renewable resources as raw materials, green, environment-friendly plasticizer. Many different types of environmentally friendly plasticizer, plasticizer considering performance and price factors, the current study more, broader application of environment-friendly plasticizers are two major categories: Epoxy oils and tributyl citrate category . PVC flame retardant
Epoxy oil plasticizer; epoxy oils are vegetable oils as a raw material, wide variety of sources, low price, more research conducted in recent years. China is a large agricultural country, rich in vegetable oil products, epoxy vegetable oil as a plasticizer also solve the deep processing of agricultural products and value-added. impact modifier
Epoxy plasticizer oils can be soybean oil, sunflower oil, linseed oil, castor oil and other vegetable oils obtained by epoxidation. Especially epoxidized soybean oil (ESO), the development and application of the earlier domestic an epoxy plasticizer in plastics, paints industry, new polymer materials, rubber and other industrial areas have widely used in recent years production continued to grow. ESO compatibility with PVC, low volatility, small relocation of PVC plasticizers and stabilizers, has good thermal stability and light stability. Non-toxic epoxy soybean oil, can be used as food, medicine packaging materials, toys and home decoration materials, additives. Epoxy plasticizer oil research in recent years, and gradually developed into a research hotspot. Its production of vegetable oil feedstock ethylene production methods are the focus of research.
