Application of Fine-Blend? in PBT and PBT alloys
Polybutylene terephthalate(PBT) hasgained animportant position amongthefivegeneralengineeringplastics because of its versatile and broad range of applications.However,it alsohas limitations, such as sensitive to notch, poor heat resistance under loads, easy to warp and so on. Generally, these limitations can be overcome by tougheningmodification,glassfiberreinforcementandblendwithotherpolymers.
Fine-blend products have many advantages in improving the toughness, heat resistance and processing stability for PBT and PBT Alloys.And alsoFine-blendprovides many application cases for customer reference.
1.Fine-blend? applied in PBT and PBT/GF system
1.1 How to improve the impact strength and flowability of pure toughened PBT system
SOG-02 is a kind of Glycidyl Methacrylate (GMA) functionalized polyolefin elastomer (POE-g-GMA). The introduction of epoxy groups could enhance the reactivity of POE with PBT, and then the high toughness POE chains could get a super-toughened PBT system. Compared with the traditional toughener, such as EMA-co-GMA and EBA-co-GMA, SOG-02 shows a relativity high toughening efficiency and excellent flowability at the same time (Fig1.1) in toughened PBT system. The spiral length in Fig1.2 further proved the higher flowability of toughened PBT system with SOG-02.
SOG-02 not only shows relativity high tougheningefficiency and excellent flowabilityin pure toughened PBT system compared with traditional toughener, but also shows relativity high toughening efficiency (Fig1.4) and excellent flowability(Fig1.3) in 30% glassfiberreinforcedPBTsystem(PBT/GF).
The injection spline of PBT/GF composites with different toughener underthe same injection conditions in Fig1.5 showed that the PBT/GF composites with SOG-02 need only a lower pressure to complete the injection molding.
Similarly, SOG-02 also shows an equal toughness and mechanical property in flame retardant PBT/GF (FR-PBT/GF)system compared withEMA-co-GMA and EBA-co-GMA.
From the above Fig 1.1-1.6, we can conclude that Fine-blend?SOG-02 can be used as a conventional substitute for EMA-co-GMA and EBA-co-GMA no matter in pure toughened PBT system, PBT/GF system or in FR-PBT/GF system.
1.3 How to improve the processing stability of pure toughened PBT system
SOG-03 is a upgrade POE-g-GMA based on SOG-02 that has higher grafting ratio and lower monomer residual. SOG-03 can be completely used as substitute for EMA-co-GMA and EBA-co-GMA in PBT and PBT alloys, and also showsabetterthermalstabilityandprocessability.
The SEM photograph of PBT with different toughener in Fig 1.7 showed that the disperse phase size were greatly reduced with the addition of SOG-03 compared with pure POE, and the disperse phase size of PBT with EMA-co-GMA is relativity smaller than that with SOG-03. This is because EMA-co-GMA has a higher GMA content, normally at 8wt%.
For PBT and PBT alloys, the grafting ratio of toughener is not the higher the better, higher grafting ratio may cause poor processability.TheMFR of PBT with EMA-co-GMA in Fig 1.8 was significantly decreased after multi-extrusion process,while the MFR of toughened PBT withSOG-03keeps very stable that indicatea good processability.
From the molecule structure of POE and EMA,POE hashigher thermal stability and impact performance than EMA. As shown in Fig 1.9, the impact strength of pure toughened PBT system with SOG-03 after long term thermal ageing is higher than that with EMA-co-GMA, even after the thermal ageing is more than 800h.
Similarly, the notched impact strength (Fig 1.10) and unnotched impact strength (Fig 1.11) of PBT/GF system with EMA-co-GMA and SOG-03 after long-term thermal ageing shows almost the same, even after the thermal ageing is morethan800h.
For further improve the thermal stability of PBT/GF system to meet the requirement of more harsh condition, Fine-blend? provides a solution of adding a small amount SAG-008. The solution and results in Fig 1.12 showed that the thermal stability of PBT/GF system can be greatly improved with the addition of 1wt% and 2wt% SAG-008.
From the above Fig 1.7-1.11, we can conclude that Fine-blend?sOG-03 can be completely used as substitute for EMA-co-GMA and EBA-co-GMA in PBT andPBT alloys,and also shows abetter thermal stability and processability The thermal stability of PBT/GF can be further improved with a small mount addition of SAG-008.
2.Fine-blend? applied in PC/PBT alloy
2.1 How to improve the impact strength of PC/PBT alloy
SOG-03 also can be used as toughener in PC/PBT (70/30) alloy. As shown in Fig 2.1, when the addition of SOG-03 is more than 3wt%, the PC/PBT alloy reaches brittle-to-ductile transition. The impact fracture surface of super toughenedPC/PBTalloyshowsatypical elastomertougheningmechanism.
2.2 How to improve the process ability of PC/PBT alloy
The process ability of PC/PBT alloy, such as the change of color, MFR and impact strength, with different toughener was evaluated by multi-extrusion process. As shown in Fig 2.2, the E value of PC/PBT alloy with SOG-03 is the smallest after different multi-extrusion time,EMA-co-GMA take the second place,andEvalue and colorof PC/PBT alloywithMBSwereobviouslyworse.
The MFR value of PC/PBT alloy with different toughener after multi-extrusion process inFig 2.3 showed that the MFR of PC/PBT alloy with MBS rapidly increased during the multi-extrusion process, while the MFR change of PC/PBT alloy withSOG-03is smallerthan with EMA-co-GMA.These resultsindicate that thePC/PBTalloy withSOG-03shows abetterprocessability.
Similarly, the impact strength variation tendency of PC/PBT alloy with different toughener in Fig 2.4 is the same as \triangle E and MFR. The results in Fig 2.4 showed that MBS has the lowest toughening efficiency compared with EMA-co-GMA and SOG-03, and the impact strength dramatically decreased during the multi-extrusion process, while the PC/PBT alloy with SOG-03 keep a higher impact strength during the whole multi-extrusion process, EMA-co-GMA takethesecondplace.
2.3 How to improve the heat resistance properties of PC/PBT alloy
The long-term thermal ageing property of PC/PBT alloys with different toughener was shown in Fig 2.5. Results showed that MBS has the lowest toughening efficiency in PC/PBT alloy compared with EMA-co-GMA and SOG-03, and also the impact strength decreased rapidly after different thermal ageing time. While EMA-co-GMA and SOG-03 shows similar impact strength in PC/PBT alloys when the thermal ageing time less than 40oh. However, when the thermal ageing time is more than 60oh, the impact strength of PC/PBT alloy with EMA-co-GMA was decreased very fast comparedwithSoG-03.
2.4 How to improve the thermal stability of PC/PBT alloy
Fine-blend also provides a solution for preparing flame retardant PC/PBT (FR-PC/PBT) alloy with higherthermal stability.The recipes of high thermal stability FR-PC/PBT alloys were shown in Tab 1.

The MFR of FR-PC/PBT before and after melt thermal ageing in injection molding machine were shown in Fig 2.6. The MFR of FR-PC/PBT alloy with EMA-co-GMA and SOG-O3 were both significantly increased after melt thermal ageing.However, with addition of 0.8wt% SAG-005, the MFR of FR-PC/PBT alloys with EMA-co-GMA and SOG-03 increasedslower.
Similarly,the impact strength of FR-PC/PBT before and after melt thermal ageing was also shown in Fig2.7. The impact strength of FR-PC/PBT alloys with EMA-co-GMA and SOG-03 both significantly decreased after melt thermal ageing, while the impact strength of FR-PC/PBT alloys with SOG-03 decreased slowly than that with EMA-co-GMA. However, with the addition of 0.8wt% SAG-005, the impact strength of FR-PC/PBT alloys with EMA-co-GMA and SOG-03bothdecreasedslower.
From the above Fig 2.1-2.7, we can conclude that Fine-blend@ SOG-03 is an ideal toughener in FR-PC/PBT alloy, and also shows a better thermal stability and processability compared with EMA-co-GMA and MBS.The thermal stabilityofPC/PBTalloycanbefurtherimprovedwithasmallamountadditionofSAG-005.
3.Fine-blend? applied in PBT/ABS (ASA) system
3.1 How to improve the impact strength of PBT/ABS alloy
SAG-002 can be used as compatibilizer for ABS type polymer and Polyester, such as PBT and PET. Fig 3.1 showed that the impact strength of PBT/ABS (70/30) alloy can be greatly improved with the addition of 2wt% SAG-002 as compatibilizer.
SAG-002 not only can be used as compatibilizer in PBT/ASA alloy, and also can be used as coupling agent in PBT/ASA/GF system. Fig 3.2 showed that the mechanical properties of PBT/ASA/GF system can be greatly improved withtheadditionof2wt%SAG-002.
Similarly, as showed in Fig 3.3,the impact strength of PBT/ASA/GF system also can be greatly improved with the additionof2wt%SAG-002.
4.Fine-blend? applied in PBT/PPO alloy
4.1 How to improve the mechanical properties of PBT/PPO alloy
Fine-blend@ SG-06 can be used as a compatibilizer between polyester and polyphenylene ether materials. It can be seen from Fig 4.1 that with the increase of SG-06 addition, the unnotched impact strength of PBT/PPO alloy increasedfrom 7k J/m2 to 25\ k J/m2 thetensilestrengthdoubled and theflexuralstrengthincreasedby 40% .It shows that the addition of SG-06 can significantly improve the mechanical properties of PBT/PPO alloy.
4.2 Improvement of phase state of PBT/PPO alloy by Fine-blend? SG-06
It can be seen from Fig 4.2 that PBT/PPO alloy without compatibilizer has large pits and few bulges, and the two-phase dispersion is uneven. However, PBT/PPO alloy with 4wt% SG-06 has more bulges, and the two-phase dispersion is relatively uniform. It can be explained that SG-06 is suitable for increasing the compatibility of PBT/PPO.
