III. Chemical Properties
Casfil-PA1010 stands out with its excellent chemical performance, making it a reliable choice for diverse working environments while adhering to green principles.
1. Low Water Absorption: It effectively minimizes performance changes caused by water absorption, ensuring a stable shape and consistent performance even in environments with varying humidity levels. This stability guarantees long-lasting usability and reliability in different scenarios.
2. Strong Chemical Resistance: The filament can resist erosion from a variety of chemical substances, significantly expanding its application scope in various cleaning scenarios—especially those involving chemical cleaning agents. It maintains its integrity and performance even when in contact with harsh chemicals.
3. 100% Castor Oil Composition: Casfil-PA1010 is made from 100% castor oil, completely free from dependence on traditional fossil resources. This 100% castor oil-based formula not only embodies the concept of environmental protection from the source of raw materials but also ensures excellent biocompatibility, making it extremely safe for oral contact—especially suitable for interdental brush production that requires direct contact with oral soft tissues.
4. Green & Low-Carbon: Derived entirely from 100% castor oil, Casfil-PA1010 achieves true environmental sustainability from raw material selection to production. Its 100% castor oil composition ensures it is non-toxic, harmless, and fully biodegradable, further reducing environmental impact. It is an ideal material that combines excellent performance with significant environmental value, aligning with global low-carbon development trends, and its safety and stability make it a perfect choice for interdental brushes.
Physical Performance (Ideal for Interdental Brushes)
Casfil-PA1010’s excellent physical properties, combined with its 100% castor oil composition, make it perfectly tailored to interdental brush applications. Its superior straightness (★★★★★) ensures the filament can easily reach deep between teeth to remove food residues and plaque; high tensile strength prevents breakage during use, while good bending recovery rate allows the filament to return to its original shape after bending, ensuring long service life. These properties, paired with its 100% castor oil, non-toxic and eco-friendly features, make it the most reliable material for interdental brush manufacturing.
Specifically, Casfil-PA1010’s physical properties are perfectly optimized for interdental brush production, with the following key features:
- Melting Point Temperature: 210±10℃, which ensures stable performance during the manufacturing process of interdental brushes, avoiding deformation due to high temperature during processing.
- Bending Strength (★★★★): Moderate bending strength balances flexibility and hardness—flexible enough to avoid damaging oral soft tissues when inserted between teeth, while hard enough to effectively remove food residues and plaque.
- Straightness (★★★★★): Superior straightness allows the filament to easily reach deep between teeth, ensuring thorough cleaning of hard-to-reach areas without bending or collapsing.
- Tensile Strength (★★★★★): High tensile strength prevents the filament from breaking during use, ensuring the interdental brush remains intact even when used to clean tight gaps between teeth.
- Bending Recovery Rate (★★★★★): Excellent bending recovery rate enables the filament to quickly return to its original straight shape after bending, maintaining consistent cleaning performance and extending the service life of the interdental brush.
- Carbon Footprint: For PA11 (a material similar to Nexfil™1010), Arkema has reduced its carbon footprint to 1.3kg CO₂e/kg by using renewable energy and energy-saving technologies. Adopting the same green production process, Nexfil™1010 (100% castor oil-based) also achieves a low carbon footprint, further enhancing its environmental advantages.
