Eastech PC/ABS CS400
- High toughness PC/ABS alloy
- Heat resistant (Vicat 130°C)
- Strong mechanical performance
- Low shrinkage for precision molding
- UL94 HB flame rating
- Automotive-grade durability
Product Overview
Eastech PC/ABS CS400 is a premium engineering alloy developed for applications where standard PC/ABS blends fail to meet thermal or mechanical requirements. It represents a significant step up in the CS series, offering an exceptional Vicat softening temperature of 130 °C without compromising the legendary impact toughness inherent to the series.
By meticulously balancing the toughness of ABS with the high-heat and structural rigidity of Polycarbonate, CS400 provides an uncompromising solution for automotive interiors, EV components, and high-load electrical enclosures.
Core Advantages
Top-Tier Thermal Stability: Featuring a Vicat B50 of 130 °C and an HDT of 103 °C, it is ideal for high-heat environments like dashboards and industrial switchgear.
Exceptional Impact Strength: A notched Izod rating of 55 kJ/m² provides maximum protection against mechanical failure and high-energy impacts.
High Structural Rigidity: With a flexural modulus of 2200 MPa, it maintains its shape and load-bearing capacity under constant stress.
Precision Manufacturing: Stable and predictable molding shrinkage (0.4–0.7 %) allows for tight tolerances in complex, high-precision injection molded parts.
Dimensional Integrity: Excellent resistance to deformation over time, ensuring long-term reliability in varying climate conditions.
Typical Applications
• Automotive interior trims, dashboards, and decorative housings
• Electrical connectors, enclosures, and switchgear components
• Industrial equipment covers, panels, and functional parts
• Consumer electronics casings requiring toughness and heat stability
• Any component requiring a balanced combination of strength and heat resistance

Why Choose CS400?
The Professional’s Choice for High-Heat EnvironmentsCS400 is the material of choice when standard PC/ABS blends reach their thermal limits. It is specifically designed to prevent "heat sag" in large-surface-area components, such as automotive dashboards, while providing the extreme impact resistance needed for passenger safety and industrial durability. Its consistent flow and low shrinkage make it remarkably easy to implement in existing precision molds.
