Red Polypropylene PP Smooth Hollow Plastic Balls YCPYC 12mm Sphere

Description

Product Overview

The Red Polypropylene PP Smooth Hollow Plastic Balls are engineered to deliver consistent performance across a wide range of applications. Crafted from high‑grade polypropylene, each ball is precision‑machined to achieve a perfectly smooth surface and exact diameter tolerance. Available in multiple sizes—5 mm, 6 mm, 7.75 mm, 8 mm, 10 mm, 12 mm, 15 mm, and 20 mm—these spheres provide flexibility for designers, engineers, and hobbyists alike. The hollow construction reduces weight while maintaining structural integrity, making them ideal for buoyancy, flow testing, and calibration tasks. With a bright red color for easy visual identification, the balls meet industry standards for durability and chemical resistance, ensuring long‑term reliability even in demanding environments.

Usage

These polypropylene spheres are suited for a variety of settings. In laboratory environments, they serve as calibration standards for optical sensors, particle counters, and fluid dynamics experiments. In industrial contexts, the balls are used as bearing components, agitators, and filler material for molding processes. DIY enthusiasts appreciate the lightweight nature for model making, educational kits, and decorative projects. Because the material is resistant to most acids, bases, and solvents, the balls can be employed in chemical testing rigs without degradation. Their uniform size range enables precise stacking, sorting, and automated handling in manufacturing lines, while the red hue simplifies visual tracking during quality inspections.

FAQ

What material are the balls made from?

The balls are made from high‑quality polypropylene (PP), which offers strong chemical resistance, low moisture absorption, and a smooth surface finish.

Can I order custom sizes or quantities?

Yes, we accommodate custom size requests and bulk orders. Please contact our sales team with your specific requirements, and we will provide a tailored quote.

Are the balls suitable for use in water or other liquids?

Absolutely. The polypropylene material is non‑porous and does not absorb water, making the balls ideal for submerged applications, fluid testing, and buoyancy experiments.

How do I ensure I receive the correct diameter for my project?

Each package is clearly labeled with the diameter size, and we include a detailed specification sheet. If you need verification, we can provide a certificate of conformity upon request.

What is the typical tolerance for the ball dimensions?

Our manufacturing process maintains a dimensional tolerance of ±0.02 mm, ensuring high precision and repeatability across all size ranges.
