Invisible magnetic closures have become increasingly popular in the apparel, bag, and home textile industries. Among the available options, PVC vs TPU magnetic buttons is one of the most common questions asked by product designers, manufacturers, and sourcing managers.
Both PVC and TPU magnetic buttons feature a powerful NdFeB magnet core and provide a clean, hidden fastening solution. However, they differ significantly in flexibility, durability, wash resistance, environmental performance, and suitability for application.
In this guide, we compare PVC and TPU magnetic buttons in detail to help you choose the right solution for your products.
What Are Magnetic Buttons?
Magnetic buttons, also known as invisible magnetic buttons, waterproof magnetic buttons, or sew-in magnetic closures, are fastening components that use magnetic attraction instead of traditional buttons, zippers, or snaps.
They are widely used in:
- Apparel and fashion garments
- Handbags and leather goods
- Gift packaging
- Home textile products
- Stationery and storage accessories
Unlike conventional fasteners, magnetic buttons create a seamless appearance while offering convenient opening and closing.
How Invisible Magnetic Buttons Work
A magnetic button typically consists of two matching parts that attract each other when brought together.
Three-Layer Internal Structure
1. NdFeB Magnet Core
The core contains a high-performance N35–N52 neodymium magnet, providing strong and reliable magnetic force.
2. Iron Shell
A steel or iron casing surrounds the magnet to:
- Concentrate the magnetic flux
- Increase holding force
- Reduce magnetic leakage
3. PVC or TPU Outer Coating
The outer coating fully encapsulates the magnetic assembly, providing:
- Waterproof protection
- Rust resistance
- Fabric compatibility
- Easy sewing or heat-sealing
This structure makes invisible magnetic buttons suitable for garments, bags, and textile applications.
Why Use PVC or TPU Covers?
Both PVC and TPU coatings significantly improve the functionality and appearance of magnetic buttons.
Excellent Durability
PVC and TPU materials offer strong abrasion resistance and help protect the internal magnet from damage during daily use.
Reliable Waterproof Performance
The sealed coating prevents moisture from reaching the magnet core, improving product lifespan in humid environments.
Enhanced Appearance
The smooth, clean surface creates a premium look while maintaining an invisible fastening effect within fabrics.
PVC vs TPU Magnetic Buttons: Key Differences
Material and Flexibility
PVC Magnetic Buttons
- Relatively rigid structure
- Good dimensional stability
