Engineered with advanced materials and optimized for the changing oral care requirements of the regional Bangladesh market.
The Rajshahi Division in northwestern Bangladesh is experiencing a rapid urban and economic expansion. Improved regional healthcare infrastructure, together with literacy programs from local institutions like the University of Rajshahi, has raised regional hygiene awareness. As a result, consumer demand has transitioned from basic traditional cleaning tools to advanced oral care options, with a focus on ergonomic and hygienic features.
Local businesses and distributors in Rajshahi face the challenge of securing high-quality adult toothbrushes that meet international dental standards. Historically, regional supply chains relied on low-end local production or uncertified imports, which often featured coarse bristles that contributed to gum abrasion. Establishing direct trade channels with integrated manufacturers provides Rajshahi distributors with access to high-performance PBT filaments, BPA-free plastics, and customizable OEM/ODM options.
Shenzhen Jiasheng Industrial Co., Ltd. was established in 1991. At the beginning of our 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.
Because we want to get closer to consumers and understand the market needs in depth so that materials can be used more widely, in 2008 we joined forces with downstream manufacturers to start the production of hair brushes, toothbrushes, makeup brushes, and finished false eyelashes.
As plastics pollute the environment increasingly, we are also 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.
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 to achieve resilient global production capacity.
Our ongoing development in polymer science, bristle tapering technology, and automated manufacturing systems.
Utilizing PBT (Polybutylene Terephthalate) instead of standard nylon. PBT absorbs less water, retains its stiffness when wet, and provides better elasticity. This extends the service life of the toothbrush by up to 50%.
Chemical and mechanical grinding methods taper filament tips down to 0.01mm. This enables effective plaque removal in subgingival areas and tight interdental spaces while minimizing irritation to sensitive gum tissues.
Supporting the transition away from traditional plastics through research into PCR (Post-Consumer Recycled) handles, biodegradable PLA, and natural wheat-straw compounds, helping to reduce carbon footprint.
By integrating filament extrusion directly with our toothbrush assembly line, we maintain control over production costs, material purity, and turnaround times. In contrast to factories that outsource their filament sourcing, Jiasheng handles development from raw polymer formulation to final packaging.
Our facilities use high-speed automated tufting machinery to ensure uniform bristle retention and clean trims. For international shipments destined for South Asian trade hubs like Chittagong, Mongla, and onward transport to Rajshahi, this structural integration translates to consistent supply, minimized shipping delays, and competitive pricing.
Providing multi-level customization options to meet the target market requirements of different customers.











A technical overview comparing standard dental polymers with Jiasheng's advanced formulations.
| Material Classification | Tensile Recovery Rate | Water Absorption Rate | Environmental Classification | Average Lifetime (Months) | Rajshahi Suitability Index |
|---|---|---|---|---|---|
| Standard Nylon 6/6 | ~65% | > 2.5% | Fossil-Fuel Non-degradable | 1.5 to 2 Months | Low (Rapid mold growth in humid weather) |
| Advanced PBT (Jiasheng Grade) | > 85% | < 0.4% | Recyclable Polymer | 3+ Months | Excellent (High stiffness retention in damp environments) |
| Post-Consumer Recycled (PCR) Handle | N/A (Rigid Polymer) | < 0.1% | Recycled Polymer | N/A (Recycled handle shell) | High (Reduces regional waste burden) |
| Polylactic Acid (PLA) / Bio-materials | ~70% | ~1.2% | Industrial Biodegradable | 2.5 Months | High (Eco-friendly choice for sustainable brands) |
