How Silicone and PVC Differ in Manufacturing and Application

Silicone and PVC serve diverse industries, but their production methods differ significantly. Below, we highlight five key distinctions in their manufacturing processes and applications.

1. Raw Material Properties

  • Silicone: Derived from silicon, oxygen, carbon, and hydrogen, making it heat-resistant and flexible.

  • PVC: A thermoplastic made from polyvinyl chloride resin, requiring plasticizers for flexibility.

  • The Independence soft PVC rubber patch filling machine ensures smooth and uniform PVC patch production.

2. Processing Temperatures

  • Silicone requires high-temperature curing, often exceeding 180°C.

  • PVC is processed at lower temperatures, making it more energy-efficient.

  • The Independence Day soft PVC rubber patch filling machine maintains optimal temperature settings for detailed, multi-color PVC patches.

3. Environmental Impact

  • Silicone is non-toxic and biodegradable, making it safer for prolonged use.

  • PVC can release harmful chemicals if improperly processed.

  • The soft PVC rubber patch for patriotic events filling machine ensures a safe and controlled production process.

4. Longevity & Resistance

  • Silicone withstands UV rays, extreme heat, and chemical exposure.

  • PVC is durable but less resistant to temperature extremes.

  • The National holiday soft PVC rubber patch filling machine enhances the durability of custom patches for outdoor events.

5. Usage Scenarios

  • Silicone is used in medical devices, cookware, and high-heat applications.

  • PVC is ideal for keychains, decorative patches, and promotional items.

  • The American flag soft PVC rubber patch filling machine is designed for bulk production of patriotic patches, especially for 4th of July celebrations.
