On August 15, the Ecological and Environmental Code of the People's Republic of China officially took effect. The new code explicitly prohibits and restricts the production, sale, and use of non-biodegradable single-use plastic products, such as plastic bags, with fines for non-compliant enterprises reaching up to 100,000 RMB. As a result, transitioning to biodegradable alternatives has become an inevitable trend for green upgrades across industries.

Made from renewable bio-based raw materials, BioFil monofilaments decompose completely into water, carbon dioxide, and natural compost in specific composting environments. The entire process leaves zero residue and zero pollution. By achieving 100% full biodegradability, it completely eliminates the environmental impact associated with traditional plastic filaments.

Pure Natural Degradation: 100% Eco-Friendly and Safe

Unlike traditional petroleum-based filaments, BioFil naturally breaks down into carbon dioxide and water under composting conditions. Its degradation products are completely non-toxic, placing no burden on flora, fauna, or natural ecosystems.

From raw material sourcing to product use and final disposal, BioFil’s entire life cycle seamlessly integrates into the natural ecosystem. It enables brush manufacturers to produce fully degradable products, ensuring end-to-end environmental safety from production to disposal.

BioFil has successfully passed testing by authoritative third-party organizations and complies with major international standards for compostable materials, including European EN 13432 and American ASTM D6400. It has cleared multiple core evaluations—such as chemical substance limits, biodegradation, and disintegration—ensuring its degradation performance is reliable, proven, and fully verifiable.

Chemical Substance Limits: Mandates that compostable materials contain >50% volatile solids, with heavy metals (copper, zinc, nickel, cadmium, lead, mercury, chromium, molybdenum, selenium, arsenic) and fluorine strictly below specified limits.

Biodegradation Testing: Requires controlled compostable materials to convert >90% into carbon dioxide, water, and minerals within a maximum of 6 months under aerobic composting conditions.

Disintegration Performance: Specifies maximum usable material thickness. Under aerobic composting, the material must disintegrate by >90% into fragments small enough to pass through a 2mm sieve within 12 weeks.

Ecotoxicity Testing: Assesses plant survival and biological traits after introducing compost derived from the material, requiring a survival rate of >90% compared to control samples.

Furthermore, building upon European EN 13432 standards, the Australian Standards Committee introduced additional earthworm ecotoxicity testing. Taihing’s BioFil bio-based filament has already successfully passed this earthworm ecotoxicity evaluation through third-party testing.

Comprehensive Performance Upgrade: Overcoming the Limitations of Traditional Degradable Materials

Standard Polylactic Acid (PLA) degradable materials on the market are inherently rigid and brittle. When made into filaments, they suffer from poor flexibility, low impact strength, and a high risk of snapping when bent—severely restricting the practical applications of eco-friendly brushes. Taihing's BioFil directly solves this widespread issue, dramatically improving practical performance without compromising its eco-friendly credentials.

Exceptional Toughness & Fracture Resistance:

BioFil features an optimized material structure that delivers superior impact resistance. By solving the brittleness and snapping issues common in traditional degradable filaments, it is ideal for demanding applications like biodegradable combs and cosmetic brushes, greatly enhancing product durability.

Superior Bend Recovery Rate Exceeding National Standards:
BioFil achieves a significant technical breakthrough, with its monofilament bend recovery rate far exceeding the 60% requirement set by the national standard for toothbrushes. It is one of the few degradable filaments in both domestic and international markets to achieve this benchmark, making it ideal for disposable toothbrushes and high-frequency daily items by delivering both environmental performance and an exceptional user experience.
