Under specific conditions, Lohtragon® B42, based on anhydrous Tricalcium Citrate (CAS No. 813-94-5), decomposes to generate gases, creating foam structures that enhance thermal and acoustic insulation. This makes it a highly effective blowing agent in polymer applications such as polyethylene (PE), polypropylene (PP), and polystyrene (PS), making it particularly valuable for construction and packaging industries.
As a nucleating agent, Lohtragon® B42 facilitates the crystallization process in polymers, resulting in enhanced mechanical strength, improved transparency, and reduced processing time. It is widely used in polymer systems including PP, PE (HDPE, LDPE), PET, and PBT. Additionally, when combined with physical blowing agents, it ensures uniform cell distribution within the polymer structure.
By inhibiting oxidation and neutralizing acidic by-products, Lohtragon® B42 helps maintain the stability and longevity of polymer materials such as POM, PE, PP, PET, and PBT. With its stabilizing properties, – acting e.g. as antioxidant or acid scavenger –, it thus extends the lifespan of these materials in various industrial applications.
Summarized, the key benefits of Tricalcium Citrate, anhydrous | Lohtragon® B42 in polymer applications are:
As an anti-caking and free-flowing agent, Lohtragon® B42, based on Tricalcium Citrate, anhydrous, optimizes moisture absorption, improving material handling and processing efficiency. This contributes to the production of high-quality end products and supports safe, reliable manufacturing across multiple industries.
