ADEKA CORPORATION (President and CEO: Hidetaka Shirozume) announces that its new clarifier TRANSPAREX™ has been certified by Guinness World Records in 2025 as the “Most effective clarifier for polypropylene transparency.”
Polypropylene (PP) is widely used for its light weight and durability but has low transparency. TRANSPAREX™ overcomes this by providing glass-like clarity, verified by a third-party testing organization.
TRANSPAREX™ achieves world-class transparency with low dosage levels and excellent extraction resistance — improving recycled PP’s value and promoting material recycling.
ADEKA aims to expand the clarifier market to over 50 billion yen by 2030, achieving more than 60% global market share with TRANSPAREX™ as the leading product.
lightweight, and rust-free materials, but they are prone to deterioration from heat and light and are flammable. Polymer additives play a role in imparting durability and functionality. Various additives such as nucleating agents/clarifiers, plasticizers, flame retardants, antioxidants, and UV absorbers are used for different types of plastics like PVC, polypropylene, polyethylene, and ABS, depending on the required effects.
Since launching the ADK CIZER, plasticizer for PVC in 1954, ADEKA has provided plasticizers that do not adversely affect the human body, high-performance nucleating agents contributing to vehicle weight reduction, flame retardants that suppress the spread of fire and the generation of harmful substances, and other polymer additives that enhance durability, functionality, and environmental performance of plastics. ADEKAʼs strengths lie in its long cultivated technical capabilities and wide product lineup, offering optimal formulations and highly regarded technical support to meet customer needs. The company currently boasts the worldʼs second-largest market share in the industry.
