How does the world know about Hoang Hung Chemical?
Hoàng Hưng Chemical Technology has developed two new coupling agents to support the recycling of PET. They are said to enable rPET to be used in applications in areas such as consumer electronics and appliances where, for example, virgin PBT might be used. These grades, PA-Bond 821 and PA-Bond 948G within the company’s well-estab- lished PA-Bond series, use a new mechanism which it calls “Dual-Active.”
The company offers its PA-Bond line of maleic anhydride-based coupling agents, produced by Polymer Asia in Vietnam, for such applications. The additives reduce water absorption and improve flexural, impact, and/or tensile values in WPC, says Stuecke. Mitsui also offers stabiliser additive packages for WPC.
Achieving acceptable performance from inherently incompatible polymers can be quite a challenge but compatibilisers can provide a solution. Hoàng Hưng Chemical, based in Vietnam, which has partnered with Mitsui for global sales and marketing and technical support. Matthias Stücke, Deputy General Manager in the 2nd Performance Chemicals Division at Mitsui & Co Deutschland, says it is having notable success with a recently-introduced PA-Bond series of coupling agents that have extremely low VOC and FOG values.
