Dongjin Semichem, a world-class foaming agent manufacturing company, has been synthesizing foaming agents since 1967 and is continuously developing new products. UNICELL, Dongjin Semichem’s unique brand name for chemical foaming agents and foaming catalysts, is recognized internationally for its excellent quality, accounting for 30% of the global market. UNICELL foaming agents are added to plastic or rubber and thermally decomposed or expanded at a specific temperature and pressure for a specific time to form a microscopic foam. This foam structure is lightweight, thermally insulating, soundproof, elastic, and shock-absorbing—thus the material is widely used for automotive and building interiors, shoes, wallpaper, flooring, packaging, and flotation devices. It is also expected to reduce the usage of major raw materials such as plastics and rubber. UNICELL foaming catalysts, either urea- or zinc-based, accelerate the chemical decomposition of foaming agents, thereby increasing productivity and lowering energy usage. Main products 1. ADCA : UNICELL-D series Azodicarbonamide, currently the most widely used foaming agent for plastic and rubber in the world, is supplied in particle sizes of 2 to 25 micrometers. It meets the requirements for a chemical foaming agent by being non-toxic and self-extinguishing, storing stably and safely, and generating high amounts of gas. 2. Hydrazide : UNICELL-OH, UNICELL-H, UNICELL-BSH series P,p’-oxybis(benzenesulfonyl hydrazide), p-toluenesulfonyl hydrazide, and p-benzenesulfonyl hydrazide are characterized by their absence of staining, discoloration, toxicity and their efficacy of nitrogen gas discharge. Thus, they are widely used for foaming rubber or PVC plastisol.
