Eastech PC/ABS CS300
- Ultra high impact toughness
- Extreme heat resistance (Vicat 120°C)
- Superior mechanical strength
- High structural stability
- Low shrinkage for precision molding
- Ideal for automotive underhood parts
Product Overview
Eastech PC/ABS CS300 is the flagship grade of the CS series, engineered for applications where failure is not an option. It represents the pinnacle of PC/ABS technology, offering ultra-high impact resistance combined with a significantly elevated thermal profile.
With a Vicat softening temperature of 120°C, CS300 is designed to thrive in high-stress environments—such as automotive engine bays and heavy industrial machinery—where standard alloys would soften or fracture. It provides the structural rigidity of a premium engineering plastic while maintaining the ease of processing required for large-scale manufacturing.
Core Advantages
Maximum Impact Toughness: Boasts an Izod notched impact of 55 kJ/m², the highest in its class, ensuring extreme energy absorption and durability.
Exceptional Thermal Ceiling: Optimized for high-heat environments with an HDT of 100 °C and a Vicat B50 of 120 °C.
Structural Integrity: Enhanced tensile and flexural strength make it suitable for load-bearing components that require long-term dimensional stability.
Precision Engineering: Low molding shrinkage (0.4–0.7 %) allows for the production of high-precision parts with tight tolerances.
Reliable Melt Flow: A balanced melt mass-flow rate (20 g/10min) ensures consistent part quality and stable injection molding cycles.

Why Choose CS300?
The Ultimate Structural SolutionWhen standard PC/ABS grades reach their physical limits, CS300 takes over. It is the material of choice for engineers who need to bridge the gap between general-purpose plastics and specialized high-cost resins. Whether it is resisting the intense heat of an engine bay or the blunt force of industrial impact, CS300 provides a reliable, high-strength "backbone" for your most critical designs.
