Chevron Phillips Marlex 4571 LDPE Reain
Chevron Phillips Marlex 4571 is a low density polyethylene (LDPE) for cast film, enabling high-speed extrusion for industrial, textile, and agricultural use.
Physical Properties
- Density: Measured per ASTM D-1505, the density is 0.924 g/cc (0.0334 lb/in³), influencing material weight and formability.
- Water Vapor Transmission: For 1.25 mil blown film (ASTM F-1249), the rate is 13.0 g/m²/day (0.837 g/100 in²/day), indicating moderate moisture barrier.
- Oxygen Transmission Rate: At 1.25 mil blown film (ASTM D-3985), the rate is 6100 cc/m²/day (393 cc/100 in²/day), suitable for non-hermetic packaging.
- Melt Index of Compound: As per ASTM D-1238, it is 4.1 g/10 min at 190°C under 2.16 kg, ensuring good processability for extrusion.
- Antiblock/Slip Levels: Both at 0.00 ppm, meaning no additives are included to prevent sticking or reduce friction.
Polymer Properties:
- Base Material: Low Density Polyethylene (LDPE)
- Modification Features:
- Tailored for cast film with high-speed extrusion capability to meet industrial throughput.
- Provides dimensional stability and consistent film quality at high speeds.
Applications:
- Personal Care and Hygiene Films:
- Marlex® 4571 is exceptionally well-suited for the production of films used in the personal care market, such as the backsheet for diapers, adult incontinence products, and feminine hygiene products.
