Case1. Application of SAG-008 in recycled PC
Fig 1. Effect of SAG-008 on melt index of R-PC(260 ℃ × 2.16kg)
Fig 2. Effect of SAG-008 on tensile strength and flexural strength of R-PC
As shown in Fig 1 and Fig 2, the melt index of recycled PC decreases with the increase of SAG-008 content. It indicates that SAG-008 have a good effect on thickening and chain extension. The tensile strength and flexural strength are improved. It shows that SAG-008 can restore the inherent performance R-PC by chain extension in recyclable materials.
Case 2. Application of SAG-008 in recycled PET

Fig 4. Effect of SAG-008 on tensile strength and flexural strength of R-PC
As shown in Fig 3 and Fig 4,the melt index of recycled PET decreased with the increase of SAG-008 content. It indicates that SAG-008 have a good thickening and chain extension effect. However, the tensile strength and flexural strength were raised to some extent. It shows that SAG-008 can restore the inherent performance recycled PET by chain extension.
Fig 5. Effect of SAG-008 on molecular weight distribution of R-PET
As shown in Fig 5, polydispersity index of the molecular weight of R-PET decreases with the increase of SAG-008 content continuously. It indicates that more uniform molecular weight of R-PET.
Case 3. Application of SAG-008 in recycled PA
Fig 6.Effect of SAG-008 on melt index of R-PA66(260 ℃ × 2.16kg)
Fig 7.Effect of SAG-008 on tensile strength and flexural strength of R-PA66
As shown in Fig 6 and Fig 7, the melt index of recycled PA66 decreases with the increase of SAG-008 content. It indicates that SAG-008 has a good thickening and chain extension effect. However, the tensile strength and flexural strength are raised to some extent. It shows that SAG-008 can restore the inherent performance of recycled PA66 by chain extension.
SAG-008 enhanced the molecular weight of recycled PA66
MALDI TOF MS high linearity mode determination, molecular weight results from polymerix software was as following:
As shown in Tab 3, after adding the SAG-008, the molecular weight of recycled PA66 increased and the molecular weight distribution became narrower.
Recommended dosage
1-5%
