Core Advantages of 3C Pyramid Abrasive Technology
Consistent Scratch Pattern
Structured pyramid abrasives ensure uniform cutting, eliminating random deep scratches common with conventional sandpaper.
Stable Cutting Performance
Self-renewing abrasive structure maintains consistent cutting ability throughout the product life cycle.
Reduced Polishing Time
Fine and even scratch pattern significantly shortens subsequent polishing steps.
Lower Rework Rate
Improved surface consistency reduces defects and rework in production.
Operator-Friendly Performance
Foam-backed design minimizes pressure variation, reducing dependence on operator skill.
Multi-Layer Construction for Industrial Performance
This sanding disc is engineered with a 5-layer composite structure to balance cutting efficiency and surface control:
1. Structured Abrasive Layer (Pyramid Technology)
Precisely engineered micro-replicated abrasive structures for controlled and uniform material removal.
2. Film Backing (Polyester Film)
High-strength, tear-resistant backing for durability and edge stability at high speeds.
3. Transition Layer
Optimizes force distribution and prevents aggressive cutting marks.
4. PU Foam Layer (Orange Layer)
High-resilience foam provides cushioning, improves surface conformity, and absorbs vibration.
5. Hook and Loop Backing
Quick-change system compatible with standard backing pads, improving operational efficiency.
