Introduction
Plasticizers: Enhancing Polymer Performance
1. Definition & Function
- Plasticizers are additives incorporated into plastics, resins, and elastomers to:
- ✅ Increase flexibility and reduce brittleness.
- ✅ Lower the glass transition temperature (Tg), improving softness and elongation.
- ✅ Enhance processability (ease of molding, extrusion, etc.).
2. Key Properties
| Property | Description |
|---|---|
| Compatibility | Must be miscible with the polymer (e.g., phthalates in PVC). |
| Volatility | Low volatility ensures long-term performance. |
| Thermal Stability | Resists degradation at processing temperatures. |
| Toxicity | Some phthalates are restricted (e.g., DEHP); alternatives like DOTP are safer. |
3. Common Types
| Type | Examples | Applications |
|---|---|---|
| Phthalates | DEHP, DINP, DIDP | PVC products (cables, flooring, toys). |
| Non-Phthalates | DOTP, ATBC, TOTM | Medical devices, food packaging. |
| Polymeric | Polyesters, adipates | High-performance elastomers. |
| Bio-based | Citrates, soybean oil | Eco-friendly plastics. |
4. Applications
- Automotive
- Soft PVC for wire insulation, dashboards, and seals.
- Medical
- Flexible tubing, blood bags (non-toxic plasticizers required).
- Packaging
- Food wraps, cling films (ATBC, acetyl tributyl citrate).
- Coatings & Adhesives
- Improves film flexibility and adhesion.
5. Safety & Regulations
- Restricted Plasticizers: DEHP, DBP (banned in toys and childcare products under REACH, RoHS).
- Alternatives:
- DOTP (DEHP-free) for cables and medical applications.
- Epoxidized soybean oil (ESBO) for food-contact materials.
