Glyceride is a lubricant and plasticizer commonly used in the polymer industry. It enhances the flexibility, flow, and processing of plastics and rubber. Glyceride is also used to improve the dispersion of fillers and pigments in various polymeric systems. It is especially effective in PVC, PE, PP, and other thermoplastics.
| Property | Typical Value |
|---|---|
| Appearance | Light yellow liquid |
| Viscosity | 50 – 200 cps (at 25°C) |
| Acid Value | ≤ 5 mg KOH/g |
| Specific Gravity | 0.92 – 0.96 g/cm³ |
| Flash Point | 180 °C (min) |
| Problem | Glyceride Solution |
|---|---|
| High extrusion pressure or friction | Reduces friction, improving flow and processing |
| Inconsistent filler dispersion | Improves filler and pigment dispersion |
| Low flexibility and processability | Increases flexibility and ease of processing |
| Poor surface finish or rough texture | Improves surface smoothness and gloss |
Q1: Is Glyceride compatible with all types of plastics?
Yes, it is compatible with a wide range of thermoplastics, including PVC, PE, and PP.
Q2: Can it be used in food packaging applications?
Food-grade versions of Glyceride are available for approved applications.
Q3: How is it added to the formulation?
Glyceride is typically added at 1% – 5% depending on the required properties.
