1. Calcium-Zinc Stabilizers
- Environmentally friendly
- Non-toxic
- Excellent thermal stability
2. Lead-Based Stabilizers
- Highly effective
- Cost-efficient for certain applications
- Regulatory restrictions due to toxicity
3. Organotin Stabilizers
- Good thermal and light stability
- Suitable for a broad range of applications
4. Mixed Metal Stabilizers
- Combines benefits of various stabilizers
- Versatile and adaptable for many formulations
