In the world of engineering plastics, the demand for high-purity and eco-friendly materials is rising. Mass polymerization ABS (Bulk ABS) stands out due to its excellent thermal stability and gloss-free wastewater discharge. As a direct distributor for Sinopec, Qingdao Prime Union Trade Co., Ltd. is proud to introduce a top-tier Mass ABS grade from Sinopec Shanghai Gaoqiao Petrochemical.

This grade is designed for demanding applications in the automotive, electronics, and construction sectors. Below are its key physical properties:
| Property | Test Standard | Value | Unit |
|---|---|---|---|
| Melt Flow Index (220℃ 10kg) | ISO 1133 | 9.5 | g/10min |
| Tensile Strength (Yield) | ISO 527 | 31 | MPa |
| Charpy Impact (23℃) | ISO 179 | 10 | kJ/m² |
| Gloss (60°) | ASTM D523 | 15 | % |
| Vicat Softening Temp (50N) | ISO 306 | 97.5 | ℃ |
While several companies have announced Mass ABS capacity in China (totaling 670,000 tons by 2024, according to JLC), stable mass production remains a challenge for newcomers.
New Players: Companies like Guangxi Changke (focusing on transparent ABS/AS/HIPS) and Xinyu Chemical (producing HIPS after restart) have yet to achieve stable qualified mass ABS output.
Stable & Reliable Producers: The market relies on established giants like Gaoqiao Petrochemical, North Huajin, Chimei, and Zhangjiagang Styron.
Sinopec’s mass ABS, produced by Gaoqiao, benefits from decades of process optimization, resulting in extremely low odor—a critical factor for automotive interior applications.
Qingdao Prime Union Trade Co., Ltd. is not just a trader; we are your material solution partner.
Tier-1 Authorized Distributor: We hold official agency status for CHIMEI, Hyosung, and Hanwha.
Direct Cooperation: We have built strong partnerships with Sinopec, Double Elephant, and Kingfa.
