Blow Molding Materials

HDPE

HDPE is a prime candidate for blow molding due to its high strength-to-density ratio, chemical resistance, and processability. HDPE is lightweight, durable, and recyclable and is well suited for large volume usage. HDPE is used extensively for milk, detergent, and household chemical bottles, industrial drums and pails, and containers. Its impact strength and environmental stress cracking resistance deliver long-term performance in hostile applications.
