Comparison of SABIC PP 575P and C30S


When venturing into the vast world of polypropylene homopolymers, one needs a keen eye to distinguish between the nuanced properties of materials such as SABIC® PP 575P and C30S. Let's embark on an enlightening journey to compare these two contenders, unearthing their peculiarities and discovering which champion suits various industrial gladiator arenas.

What is Polypropylene Homopolymer?

Imagine a versatile plastic warrior, adept in the art of transformation, serving in arenas from mundane packaging to high-octane automotive parts. Known for its resilience, chemical combat skills, and adaptability, polypropylene homopolymer is that unsung hero in the polymer pantheon.

Detailed Comparison of SABIC PP 575P and C30S:

Melt Flow Rate (MFR):

  • SABIC PP 575P: 11 g/10 min

  • C30S: 6 dg/min

  • Observation: SABIC PP 575P boasts a higher MFR, suggesting it flows like a swift river under heat, ideal for the rapid-fire world of injection molding.


  • SABIC PP 575P: 905 kg/m³

  • C30S: 900 kg/m³

  • Observation: Almost twins in density, these materials offer a balanced weight class, perfect for applications where the weight is a heavyweight factor.

Tensile Strength at Yield:

  • SABIC PP 575P: 35 MPa

  • C30S: 34 MPa

  • Observation: Nearly neck and neck, both materials show a robust resistance to pulling forces, a testament to their tenacity.

Elongation at Yield:

  • SABIC PP 575P: 11%

  • C30S: 13%

  • Observation: C30S stretches a tad more, providing that extra give for applications demanding a bit of a stretch before giving up.

Flexural Modulus:

  • SABIC PP 575P: 1600 MPa

  • C30S: 1500 MPa

  • Observation: SABIC® PP 575P takes a slight edge with greater stiffness, a critical factor when rigidity is the rule of the game.

Notched Izod Impact Strength:

  • SABIC PP 575P: 22 J/m

  • C30S: 4 kJ/m²

  • Observation: Here, a straight comparison turns into a conundrum; however, C30S might just absorb shocks with a bit less grace than its counterpart.

Vicat Softening Point:

  • SABIC PP 575P: 153 °C

  • C30S: 155 °C

  • Observation: Both materials start softening around the same fiery temperatures, suitable for roles in high-heat scenarios.

Heat Deflection Temperature:

  • SABIC PP 575P: 98 °C

  • C30S: 112 °C

  • Observation: C30S withstands higher temperatures before bowing to pressure, making it a prime candidate for high-temperature applications.

Additional Considerations: While SABIC PP 575P is tailored for the swift dances of injection molding, C30S shines in the steady strides of extrusion processes.

Conclusion: In the grand coliseum of industrial applications, both SABIC PP 575P and C30S present formidable properties. Your choice might hinge on the specific nuances of flow rate, flexibility, and temperature tolerance. Whether your battle calls for quick fluidity or enduring flexibility, choose your champion wisely!
