Plasticizers for plastic raw materials - OKCHEM - Global
Plasticizers is a high boiling point and low volatility of the material. Its molecular structure has polar and non-polar parts. Plasticizer molecules can be inserted between the polymer chains to weaken the intermolecular forces and increase the distance and space between the molecular chains of polymers, as well as increase polymer plastic and reduce the processing temperature of the polymer.

- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- What are bio-based plasticizers?
- As the name says, biobased plasticizers are majorly based on: Few more plasticizers are based on renewably sourced isosorbides and alkanoic acids. Isosorbide diesters are a non-toxic alternative to phthalates. They offer promising properties to PVC. Being naturally/renewable sourced, bio-based plasticizers are sometimes easily approved for:
