TPU Raw Material for Reflective Zippers
Product Description
A thermoplastic polyurethane raw material specifically designed for producing high-visibility safety reflective zippers.
Key Characteristics
1. Excellent Weather & Aging Resistance: Long-lasting reflective effect, resistant to UV, washing, and abrasion.
2. Superior TPU Base Properties: Maintains high flexibility, low-temperature resistance, abrasion, and tear resistance.Main Applications
Reflective zippers on outdoor sportswear, safety protective clothing, reflective backpacks, footwear, cycling gear; reflective tapes for traffic safety signs.
Processing Methods
Co-extrusion (Primary, for reflective tape), Injection Molding (for reflective zipper teeth).
Environmental & Safety Certs.
ROHS, REACH, can comply with relevant requirements of EN 20471 (high-performance reflective material standard).
Color
Transparent/semi-transparent base (for covering the reflective layer), or made in gray, silver, etc.
Storage Conditions
Strictly moisture-proof and light-proof. Store sealed in a dry, cool environment (<25°C).
Packaging
20/25 kg/bag

Parameter/Guideline
Drying
95-105°C / 4-5 hours (Mandatory and thorough)
Processing Temperature
180 - 200 °C (Strict control to protect the reflective structure)
Critical Precautions
1. Protection of Reflective Layer: During co-extrusion or subsequent processing, prevent high temperature and pressure from damaging the reflective beads or prismatic structure.
2. Weathering Tests: Finished products must undergo rigorous washing, abrasion, and UV aging tests to ensure the durability of reflective performance.Purge Suggestion
Purge thoroughly with transparent-grade ABS or HIPS. More thorough purging is required after processing different colors or filled grades to prevent contamination.
