- Ultra-Fast Defoaming Efficiency
- Nano-sized defoamer particles (≤100nm) achieve ≥95% foam reduction within 30 seconds of melt contact (ISO 8217), eliminating surface blisters, cloudiness, and voids in plastic products.
- Surface tension reduction technology (Δγ ≥30mN/m) disrupts bubble stability, even in high-viscosity resins like PC and PA.
- Low Migration & Food Safety
- compliant formulations (21 CFR 178.3297) ensure ≤0.01ppm migration in food packaging applications, ideal for HDPE milk bottles and PP food containers.
- Heavy metal content ≤5ppm (EN 1122), suitable for medical device components (USP Class VI).
- Multi-Resin Compatibility
- Compatible with PE, PP, PS, ABS, PC, and engineering plastics, performing optimally in extrusion (180-300℃), injection molding (220-280℃), and blow molding processes.
- Customizable for low-odor applications (VOC ≤10ppm) in automotive interiors and electronics.
- Thermal Stability
- Withstands processing temperatures up to 300℃ (IEC 60216-1), maintaining defoaming efficacy in high-temperature resins like PPS and PEEK.
- UV-stabilized variants resist yellowing under 5000+ hours QUV aging (ISO 4892-3), suitable for outdoor applications.
Applications
- Packaging
- HDPE/LDPE films with haze reduction (≤2%) and optical clarity for premium packaging.
- PP/PS food containers with FDA-compliant defoaming for hot-fill applications.
- Automotive
- PP/ABS dashboard panels with surface finish RA ≤0.8μm (ISO 4287) and UV resistance.
- PA6/PA66 engine components with high-temperature stability (≥280℃).
- Medical
- PP syringes and PE IV bags with low extractables (≤0.1mg/kg) and USP Class VI compliance.
- PC medical lenses with bubble-free transparency for optical devices.
- Industrial
- PVC pipes with reduced extrusion pressure fluctuations (±5% variance).
- PET strapping tapes with improved tensile strength (≥200MPa) through void elimination.
