FREQUENTLY ASKED QUESTIONS (FAQ)
Q1: How does PET spunbond compare to PP in strength?
*A: PET offers 2X tensile strength at identical weights (e.g., 80 gsm PET = 160 N/5cm vs. PP's 80 N/5cm) with superior creep resistance.*
Q2: What recycled content options exist?
A: We provide:
• 30% rPET: Food-contact compliant (FDA 21 CFR 177.1630)
• 70% rPET: Carbon-neutral (ISO 14067)
• 100% rPET: Ocean-bound plastic certified
Q3: Can PET spunbond withstand welding/seaming?
A: Yes. Optimized for:
• Ultrasonic bonding (20 kHz)
• Hot air welding (220°C)
• RF sealing (27 MHz)
Q4: What UV stabilizers do you use?
A: Dual-system protection:
• Hindered Amine Light Stabilizers (HALS)
• *Carbon black (2-4% loading)*
- *Guaranteeing 10-year outdoor service life.*
Q5: Do you offer fire-retardant grades?
A: Certified options include:
• UL 94 V-0 (phosphorus-nitrogen system)
• EN 13501-1 B-s1,d0 (non-halogenated)
• NFPA 701 (theatrical drapes)
Q6: What's your production capacity?
A:
• *Line speed: 400 m/min*
• *Monthly output: 1,200+ tons*
• Widths: 1.6m, 3.2m, 5.4m (custom slitting)
