Guinness Officially Certifies Japan Company's Breakthrough Transparency Technology

The company's new high-performance clarifying agent, Transparex, enables polypropylene to achieve a haze as low as 2.2% (1mm thickness), resulting in a glass-like clarity.

In addition to peculiar records such as "the most consecutive jumps by a cat in one minute (9 times)" and "the most live snails placed on a human face (43 snails)," the Guinness World Records has recently added a new member. Japanese additive supplier Adeka has announced that its next-generation high-performance transparent agent, Transparex, has officially received the Guinness World Record certification for "the best transparency agent for polypropylene" for the year 2025.

Achieving low haze with low additive levels.

Transparex, as a new type of high-performance clarifying agent, can achieve a haze of 2.2% in polypropylene (at a thickness of 1mm), significantly improving compared to the best value of 3.2% from similar products. Notably, Transparex can achieve this level of haze with an extremely low addition amount and possesses excellent extractability resistance. This product can also provide transparency and functionality to recycled polymers without being affected by residual additives, effectively promoting the material recycling process.

At the recent K Show in Germany, Adeka, in collaboration with South Korean polypropylene composite manufacturer CEPLA, showcased a transparent homopolymer PP bumper prototype developed with Transparex, highlighting the product's potential applications beyond the rigid packaging sector.

"Transparex optimizes the light diffusion effect, allowing designers to integrate LED lighting systems into automotive components such as bumpers," explained Chotaro Kijima, Vice President of Adeka's Polymer Additives Division in Europe.

Since its launch in November 2024, Transparex has received positive feedback from customers across various fields. The company plans to achieve sales of over 5 billion yen (approximately 328 million USD) for this product by fiscal year 2030, a significant increase from 3 billion yen in 2024, and aims to capture over 60% of the market share by then, up from just 14% in 2024.
