Formula: LDPE
Form: Disk
Material: Low Density Polyethylene (LDPE)
CAS Number: 9002-88-4
Commodity: Polymers
The LDPE (low-density polyethylene) Disk is available in a comprehensive range of 154 variations. LDPE is known for properties such as toughness, flexibility, chemical resistance and low moisture absorption. These disks have applications in industries like packaging, consumer goods, construction, and automotive manufacturing, where properties like impact strength, electrical insulation and ease of processing are valued. Thanks to our wide choice of sizes and thicknesses available, Goodfellow's LDPE disks can suit diverse application requirements.
