SBC Impact Modifier
Impact resistance and/or environmental stress cracking resistance (ESCR) are critical parameters when using styrenic polymers in applications involving direct contact with oil, or any greasy material.
For polymers such as ABS or HIPS, it is not always easy to find a solution combining both. |

Solution for impact resistance and stress cracking resistance...
|
|
Styroflex®, a styrene-butadiene block copolymer offers both impact and stress cracking resistance.
Besides providing these benefits, Styroflex® also improves tear and puncture resistance. Furthermore the upgraded material is easy to process and shows excellent thermoformability.
Styroflex®, produced by BASF, demonstrates good performance, for both HIPS and ABS, as highlighted by the examples below : |
| ABS |
HIPS |
| ECSR in ABS is improved by 58% with 3% of Styroflex® |
With only 3% of Styroflex®, the stress cracking resistance is improved by 43% |
 |
 |
| Puncture resistance is improved, thanks to Styroflex® |
A few percent of Styroflex® brings ductility to HIPS |

Suitable for oily, fatty applications...
|
|
Don't compromise between performance and appearance . Styroflex® doesn't impact glossiness. |
Examples of applications where Styroflex® is used:
|
HIPS / Styroflex - blend.
Application: ice cream lids |
ABS/ Styroflex- blend.
Application: refrigerator liner |
