Ergonomic Dual-Material (PP+TPR) Bottle Cleaning Brushes with Resilient PP Bristles (Custom Sizes & Shapes)

# Dual-Material (PP+TPR) Ergonomic Container & Bottle Cleaning Brushes

## Next-Generation Non-Slip Cleaning Tools for Global Importers, Retailers & Brand Owners

Engineered for superior tactile control and wet-hand ergonomics, our **Dual-Material (PP+TPR) Bottle Brush Series** solves the slip and hand-fatigue issues common to traditional hard-plastic scrubbers. 

Combining a structural Polypropylene (PP) core with an over-molded Thermoplastic Rubber (TPR) grip, these brushes deliver high cleaning leverage inside deep thermal flasks, glass carafes, narrow-neck bottles, and food storage vessels. Manufactured using multi-station, double-shot automated injection molding and precision tufting machinery, our production line offers flawless unit-to-unit consistency alongside unparalleled high-volume manufacturing cost advantages.

### Strategic Advantages for Overseas Importers & Category Managers

#### 1. Premium Dual-Injected Non-Slip Ergonomics

Unlike single-injection plastic brushes that become slick when covered in soap and water, our custom TPR over-molded zones provide exceptional friction and cushioning. The ergonomic thumb rest and palm contours reduce user strain during repetitive commercial or household cleaning tasks, giving your retail brand a distinct performance edge over competitors.

#### 2. Non-Toxic, Odorless & Food-Contact Certified Materials

In high-end housewares and nursery care, safety compliance protects brand equity. Our PP framework, TPR grips, and PP bristle clusters are produced strictly from virgin, food-contact grade resins that pass stringent **FDA** and European **LFGB** chemical migration standards. The non-porous TPR formulation resists mildew, water logging, and discoloration over prolonged use.

#### 3. Ultra-Lock Bristle Tufting & Dishwasher Fatigue Resistance

Loose bristles damage customer trust. We utilize high-speed automated staple-tufting technology to anchor every bristle bundle deep into the molded handle head using corrosion-proof metallic anchors. Combined with heat-set PP bristles, these brushes withstand over 50 commercial dishwasher wash cycles without handle delamination or bristle deformation.

#### 4. Spatial Packing Efficiency & Low Landed Freight Footprint

To maximize your ocean container CBM utilization, our handle designs incorporate stack-friendly nesting curves and slim profiles. This engineered geometry allows maximum cartoning density, lowering per-unit ocean freight and fulfillment costs across global logistics networks.

#### 5. "Zero-Tooling Risk" Free Dual-Shot Injection Mold Program

### Stringent Factory Quality Assurance & Testing Standards

Every production run undergoes strict inline QC protocols under AQL 1.5 standards:

1. **TPR Adhesion & Peel Test:** Mechanical shear testing to verify zero delamination between the TPR grip and PP frame under extreme twisting force.

2. **Tuft Pull-Out Resistance:** Tensile force testing ensuring bristle anchor retention meets or exceeds international safety benchmarks.

3. **Thermal Fatigue & Chemical Immunity:** Accelerated wash-basin testing with hot grease, detergent solvents, and heat cycles to ensure long-term structural integrity.
