Key Manufacturing Differences Between Silicone and PVC

Silicone and PVC are widely used materials, but their production methods differ significantly. Here are the main differences in how they are manufactured:

1. Raw Materials and Processing

Silicone is derived from silicon, carbon, hydrogen, and oxygen, making it heat-resistant and flexible. PVC is a synthetic polymer that requires plasticizers for flexibility.

  • The Independence soft PVC rubber patch filling machine ensures accurate dispensing of PVC material.

  • The Independence Day soft PVC rubber patch filling machine supports precise detailing for event-themed patches.

2. Molding and Production Methods

Silicone undergoes compression molding or injection molding, whereas PVC is produced using liquid dispensing, heating, and curing.

  • The soft PVC rubber patch for patriotic events filling machine optimizes PVC molding efficiency.

  • The National holiday soft PVC rubber patch filling machine is used for large-scale production.

3. Safety and Environmental Considerations

Silicone is non-toxic and eco-friendly, making it ideal for food-grade products. PVC, however, may release harmful substances if not processed properly.

  • The American flag soft PVC rubber patch filling machine ensures compliance with environmental standards.

  • The 4th of July soft PVC rubber patch filling machine enables safe and efficient batch production.

4. Flexibility and Strength

Silicone is resistant to heat, UV radiation, and aging, whereas PVC may degrade over time in extreme conditions.

  • The Independence soft PVC rubber patch filling machine enhances patch quality and durability.

  • The Independence Day soft PVC rubber patch filling machine maintains consistent quality for all patches.

5. Design and Application

Silicone has a smooth texture and raised effects, while PVC allows for colorful, embossed, and glossy finishes, making it ideal for promotional patches.

  • The soft PVC rubber patch for patriotic events filling machine is perfect for custom event merchandise.

  • The National holiday soft PVC rubber patch filling machine ensures rapid production for seasonal products.

Choosing between silicone and PVC depends on factors like safety, durability, and intended application.
