Polyamide 610 (Nylon 610) is a premium synthetic polymer derived from sebacic acid, which is extracted from natural castor oil. As a bio-based material, PA610 offers a lower carbon footprint compared to traditional petroleum-based Nylon 6 or 66.
PA610 bristles maintain their stiffness and "flick" longer than PA6. With significantly lower water absorption, these filaments stay hygienic and effective even in the humid environments of bathrooms.
Ideal for oral care, PA610 is resistant to toothpastes, essential oils, and mouthwashes, ensuring the bristles do not degrade or lose structural integrity during their 3-month lifespan.
Modern procurement directors at companies like P&G, Unilever, and emerging eco-conscious brands are moving away from virgin plastics. PA610 represents the "sweet spot" between high-performance mechanical properties and environmental responsibility. By choosing Wholesale PA610 manufacturers, enterprises can claim 30-40% bio-based content in their brush components.

Unlike middle-men, Jiasheng integrates the production of raw filaments and finished products. This allows for unparalleled quality control from the resin pellet to the final tufted toothbrush.
Based in Shenzhen, the heart of global logistics, we ensure rapid lead times. Our upcoming expansion into Thailand and Vietnam (2024) ensures duty-free access and supply chain resilience against geopolitical shifts.
Every batch of PA610 filament is tested for FDA, REACH, and RoHS compliance. Our laboratories focus on "Tapered Filament" technology, providing a "feather-soft" feel that global consumers demand.

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.
In 2008 we joined forces with downstream manufacturers to start the production of hair brushes, toothbrushes, makeup brushes, and finished false eyelashes.
Innovation & Sustainability: We are continuously increasing the use of recyclable, degradable and other environmentally friendly materials. In response to global geopolitical uncertainties, we are building production bases in Thailand and Vietnam in 2024.
Decades of mastery in polymer extrusion and brush manufacturing.
Expanding footprint across China, Thailand, and Vietnam.
Leading the industry in biodegradable and bio-based filament application.
Customization: We can customize products according to customer needs, including design, material selection, and functional configuration.
Due to high-frequency vibration, electric toothbrushes require filaments with high fatigue resistance. PA610 bristles maintain their shape even after millions of sonic cycles.
Safety is paramount. PA610's smoothness and chemical purity make it the preferred choice for pediatric toothbrushes in the US and EU markets.
Beyond oral care, PA610 is used in massage hairbrushes for its perfect balance of rigidity and flexibility, providing scalp stimulation without irritation.
