Product type
Plasticizers are additives used to increase the plasticity or fluidity of a material, primarily in polymers and plastics. They work by embedding themselves between the polymer chains, reducing intermolecular forces and allowing for greater flexibility and workability. Commonly made from phthalates, adipates, or other organic compounds, plasticizers are essential in the production of flexible PVC and other plastic materials.
| Chemical composition | Phthalates, adipates, or other organic compounds |
| Typical dosage | 5% to 50% by weight depending on application |
| Appearance | Colorless to pale yellow liquid or solid |
| Boiling point | Varies by type, typically 200°C to 300°C |
| Flash point | Varies by type, typically above 150°C |
| Solubility | Soluble in organic solvents, insoluble in water |
When selecting a plasticizer, consider the specific application and desired properties such as flexibility, durability, and compatibility with other materials. It is important to specify the chemical composition, required performance characteristics, and any regulatory compliance needed for your industry. Quantities may vary based on production needs, so providing estimated volumes can help suppliers offer accurate quotes.
