How Silicone and PVC Differ in Manufacturing Techniques
Manufacturers often choose between silicone and PVC based on material properties, durability, and cost-effectiveness. Here are the key differences in their manufacturing processes:
1. Material Properties and Processing
Silicone is a rubber-like material with high flexibility and resistance to extreme temperatures, whereas PVC is a thermoplastic polymer used for rigid and flexible applications.
2. Temperature and Molding
Silicone requires high-temperature vulcanization in a compression or injection molding machine, while PVC is processed at lower temperatures using liquid dispensing.
The soft PVC rubber patch for patriotic events filling machine creates durable patches with embossed details.
The National holiday soft PVC rubber patch filling machine produces bulk orders efficiently.
3. Safety and Environmental Impact
Silicone is eco-friendly and does not release harmful chemicals, while PVC requires plasticizers and stabilizers to maintain flexibility.
The American flag soft PVC rubber patch filling machine ensures detailed flag patches for promotional events.
The 4th of July soft PVC rubber patch filling machine mass-produces high-quality patches for national celebrations.
4. Strength and Longevity
Silicone is heat-resistant, UV-resistant, and maintains its form over time, making it suitable for extreme conditions. PVC, while strong, is less resistant to UV rays and heat degradation.
5. Applications and Versatility
Silicone provides a soft, raised effect, while PVC offers vibrant colors and glossy finishes, making it perfect for decorative items.
Choosing between silicone and PVC depends on manufacturing needs, cost, and product application.
