Summary: Plasticizers are the largest category of auxiliary agents in the modern plastics industry, playing a decisive role in promoting the development of the plastics industry, especially the polyvinyl chloride (PVC) industry. Any liquid organic compound or low-melting solid that can be uniformly mixed with resin without undergoing chemical changes, but can lower the glass transition temperature of the material and the melt viscosity during plastic molding processing, and remains unchanged itself, or although undergoing chemical changes, can be retained in plastic products for a long time and can change certain physical properties of the resin, is called a plasticizer.

　　In fact, plasticizing technology has been used since primitive society, and plasticizers originated from the inventions of primitive humans. For example: pottery - clay plus water, in ancient times, oil was dissolved in asphalt to make waterproof materials for waterproofing, filling boats, etc., where oil acts as a plasticizer; also, whale oil was used in leather to make it soft, whale oil being the most durable plasticizer; soft candy or desserts - gelatin plus water. Plasticizers can reduce the elastic modulus and tensile strength at break, improve elongation and elongation at break, improve softness, improve reversible bending strength, improve toughness and impact strength, lower the glass transition temperature, expand the applicability of polymers at lower temperatures, improve adhesion to various substrates, increase or decrease the sealability of films, improve lubrication and reduce friction, reduce electrostatic charging capacity, and improve surface gloss and appearance.

　　Uses of cold-resistant plasticizers:

　　1. Used as an auxiliary plasticizer for PVC products with high heat resistance, weather resistance, and durability, such as roof waterproof membranes and wire and cable materials.

　　2. Used as a plasticizer for non-toxic PVC products used in food packaging materials, such as non-toxic beverage bottles, refrigerator seals, medical infusion tubes, and syringes.

　　3. Used as a stabilizer for transparent PVC products, such as transparent PVC calendered films, surface films of PVC floor coverings, greenhouse films, and packaging films.

　　4. Cold-resistant plasticizers are used together with polyester plasticizers to improve the compatibility of polyester and PVC.

　　5. Used in the formulations of various PVC products as a stabilizer in combination with metal salt stabilizers to produce a synergistic effect and enhance the stabilizing effect. After the addition of plasticizers, the softness, flexibility, cold resistance, and elongation of the plastic can be increased. The hardness, modulus, glass transition temperature, melting point, softening temperature, or flow temperature of the plastic are reduced, the viscosity of the plastic is reduced, and the fluidity is increased, thereby improving the processing performance. As can be seen from the above, the key to the plasticizing effect of plasticizers is to weaken the interaction between polymers.
