ST-MS19

ST-MS19 by Starbetter Chemical Materials acts as a modifier for alloys such as SEBS, TPE, and TPR. It increases the bonding between two phase materials and improve over molding performance on polymers. It is based on S-EB-S type block polymer grafted with MAH. It can improve impact strength as well as enhances the compatibility between different engineering plastics, such as POM, PPO, PPS and COC. Recommended dosage level of ST-MS19 is 5%, that can be adjusted to 5-25% according to requirement and cost.
