Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Electronic Components: Designed as hard solid polypropylene (PP) balls for use in electronic devices, offering durability and resistance to heat and chemicals.
  • Multi-Purpose Utility: Versatile for applications beyond electronics, such as educational tools, DIY crafts, gaming accessories, or decorative elements due to their uniform 19mm size and translucent material.

Key features

  • 1. Material Technology

    • With high-strength polypropylene (PP), these balls offer superior durability and resistance to chemicals and impacts compared to softer plastics. Ideal for harsh environments or industrial applications.

  • 2. Precision Engineering

    • Thanks to injection molding technology, each ball maintains a precise 19mm diameter, ensuring consistency for electronic components or assembly processes. More uniform than manually produced alternatives.

  • 3. Versatile Customization

    • The translucent PP material allows easy customization with paints, labels, or engravings, making them adaptable for branding, educational tools, or creative projects. More flexible than opaque or pre-colored options.

  • 4. Scenario Solutions

    • Designed for electronic applications where non-conductive, durable components are essential, or as teaching aids for physics and measurement. Suitable for both industrial and educational settings.

  • 5. Structural Integrity

    • As solid-core balls, they provide enhanced strength and stability compared to hollow alternatives, preventing deformation under pressure or stress. Ideal for high-demand uses.

Supplier's note

  1. Three Technical Breakthroughs:

    • Enhanced Hardness: The Pro Model’s Shore D 75 hardness ensures resistance to mechanical stress in high-demand electronics.
    • Superior Chemical Resistance: Pro Model meets ASTM D543 Class 3, triple the industry standard, enabling safe use in corrosive environments.
    • Precision Tolerances: All models offer ±0.5mm diameter accuracy, critical for alignment in electronic assemblies.

  2. Optimal Version Selection:

    • Base Model: Ideal for general-purpose applications (e.g., educational kits) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for moderate-stress scenarios, such as craft projects requiring durability.
    • Pro Model: Best for industrial electronics or chemical-resistant applications, like sensor components or lab tools.

With the Pro Model’s chemical resistance, you can safely integrate these balls into solvent-exposed electronics. Their frosty transparency also allows for easy visual inspection of internal wiring or contents. Pair this with Shore D 75 hardness for long-term reliability in high-vibration environments.
