A new foaming agent masterbatch for a broad range of volume thermoplastics has been launched by CAI Performance Additives, the sole North American distributor of high-performance additives produced by China’s Starbetter Chemical Materials. ST-BA13MB is said to improve the efficiency and environmental sustainability of various foaming processes. It is a single-dose, formulated granule that combines a carrier, eco-friendly foaming agent, nucleating agent, dispersant and antioxidant.

According to CAI, this unique composition ensures consistent and reliable foaming results across various thermoplastics, including PP, LDPE, HDPE, HIPS, GPPS, ABS, ASA, TPE and TPO. ST-BA13MB is said to offer a solution for manufacturers seeking to enhance product performance, reduce material consumption and minimize environmental impact. Its superior foaming capabilities and ease of use is poised to grow the adoption of this form of plastics production.

Key benefits of ST-BA13MB include:

• Free from harmful substances such as azo and formamide (which can cause respiratory issues or irritate the skin, eyes, nose and throat)
• Suitable for extrusion, injection molding and blow molding processes
• Delivers uniform cell structure and adjustable decomposition speed
• Reduces shrinkage and enhances product performance
