Different Kinds of Filament Materials Has Different Durability Performance

When it comes to cleaning, the type of brush fibers can make all the difference. Let’s explore some key materials and their characteristics that can help you make informed choices for your cleaning needs.

1. Nylon Filament: The Long-Lasting service life

Nylon filaments are known as the "wear-resistant kings." In a test involving scrubbing a cast-iron pan 5,000 times over a year and a half, these bristles showed only minor splitting, significantly outperforming PP brushes, which lost bristles after just 2,000 uses.

The self-lubricating properties of nylon allow for a 30% reduction in dish soap usage. With a stiffness akin to a spring, they effectively tackle tough cleaning challenges without scratching pots, making them ideal for stubborn messes.

2. PP: The Short-Lived Trap

Many inexpensive brushes you find in supermarkets are made from PP (polypropylene). While they may be cheap at just 9.9 yuan, they come with hidden costs. After 800 scrubs on tiles in three months, they often turn white and break. Even grooming a golden retriever just 20 times can turn the brush into a tangled mess, leading to frequent replacements that add up.

3. PBT vs. PET: The Bottle Brush Showdown

When it comes to baby bottle brushes, the battle between PBT and PET is crucial. PBT fibers can withstand 3,000 scrubs against milk residue, lasting until your baby is weaned. In contrast, PET filaments last for 2,500 scrubs but tend to split after about eight months. As one mother from a baby store advises, “Choose the textured PBT for better durability and heat resistance!”

Home Tests for Longevity

You can easily test the durability of bristles at home:

• Tissue Tear Test: Nylon fibers won’t tear paper, while PP filaments will show fraying within three seconds.
• Boiling Test: After five minutes in boiling water, PP brush fibers bend into a question mark shape, while nylon remains rigid and straight—ideal for high-temperature conditions.

Lifespan Selection Guide

Here’s a quick reference for expected lifespans based on usage:

• Pot Brush / Range Hood: Nylon filaments have 3 years’ service life.

·  Baby Bottle / Surgical Brush: PBT filaments have 2 years’ service life.

·  Plastic Basin / Temporary Use: PP filaments have3 months’ service life.
