While EC-55 achieved domestic substitution of basic conductive PS, Hatro EC-65 represents a full upgrade targeting international high-grade conductive PS.
As automotive electronics, high-precision devices and high-power components demand higher material performance, overseas suppliers have further tightened technology and raised prices, keeping the high-end market in a “bottleneck” state.
Based on deep optimization of formula and processing, Hatro launched EC-65 upgraded conductive PS: stronger performance, higher stability, better heat resistance and superior molding, realizing full independence of high-end packaging materials and upgrading domestic substitution from “sufficient” to “superior”.
High-End Packaging Bottleneck: Foreign Suppliers Charge Premium Without Technology Sharing
In automotive semiconductors, industrial control, high-frequency devices and large-size carrier tapes:
- Higher and more stable resistivity required
- Improved toughness and impact resistance
- Wider temperature resistance and aging stability
- Ultra-low precipitation and high cleanliness
Overseas manufacturers used technical barriers to turn high-end conductive PS into monopoly products, leaving domestic enterprises in a passive position.
EC-65: Fully Upgraded, Compete with International Top Brands
EC-65 is deeply optimized based on the mature EC-55 system, with significant improvements in every key indicator.
1. More Precise & Stable Anti-static Performance
- Surface resistivity: 10⁵–10⁸ Ω/sq
- Smaller resistivity fluctuation under high/low temperature and high humidity
- Higher reliability for sensitive components and automotive-grade applications
2. Greatly Enhanced Mechanical Properties
- Higher impact resistance, less cracking and breaking
- Improved bending and fatigue resistance
- Stable performance in high-speed molding and placement, less deformation
3. Upgraded Heat Resistance & Aging Stability
- Higher heat distortion temperature, no embrittlement in long-term use
- Stable performance in high-temperature workshops and long-term storage
- Ideal for automotive, new energy and industrial harsh environments
4. Better Molding & Higher Yield
- Improved fluidity for thin-wall and precision structures
