In the global dental hygiene market, Nylon 612 (PA612) stands as the gold standard for high-performance toothbrush filaments. As a leading ODM Pa612 Toothbrush Filaments Supplier, we recognize that the selection of filament material is not merely a manufacturing choice but a critical factor in user clinical outcomes. PA612 is a long-chain polyamide synthesized from hexamethylenediamine and dodecanedioic acid. Unlike its counterparts PA6 or PA66, PA612 offers remarkably low moisture absorption (approx. 0.4% at saturation), which ensures that the bristles maintain their mechanical stiffness and "flick" even when submerged in the aqueous environment of the oral cavity.
For global brands and factories, transitioning to PA612 filaments represents a commitment to Information Gain—providing consumers with a product that lasts 30% longer and maintains superior plaque removal efficiency throughout its lifecycle. Our integrated supply chain, established in 1991, provides the technical backbone for this transition.
Years of R&D Expertise

SEA Factory Expansion
Shenzhen Jiasheng Industrial Co., Ltd. was established in 1991. At the beginning of its establishment, we mainly produced synthetic filaments, which were widely used in hair brushes, toothbrushes, makeup brushes, false eyelashes and other fields. After years of research and development, we have accumulated rich experience in the performance of filaments and the development and application of new materials.
In 2008, we joined forces with downstream manufacturers to start the production of finished products. As plastics pollute the environment increasingly, we are looking for ways to continuously improve the service life of our products and continue to increase the use of recyclable, degradable and other environmentally friendly materials.
The industry is moving toward Bio-PA612 derived from castor oil, reducing carbon footprints while maintaining the 100% performance integrity of traditional petroleum-based nylon.
Advancements in chemical tapering allow for ultra-fine 0.01mm tips that reach deep into the sulcus without causing gingival trauma, a key requirement for high-end ODM clients.
Integration of thermochromic indicators in PA612 filaments that change color when the brush head requires replacement, enhancing the user's oral health regime.
Professional and highly efficient service. Flexible and individualized customization.
Since our establishment, we have always prioritized investment in research and development, trying innovative processes and cutting-edge materials to improve quality and efficiency.
In response to the impact of global geopolitical uncertainties and trade barriers, we have begun preparing to build production bases in Thailand and Vietnam in 2024.
We have a strict quality management system from raw materials to finished products, ensuring that product quality meets customer requirements and providing reliable products.
We continue to explore the application of recycling and biodegradable materials to minimize carbon emissions and reduce plastic pollution.
