HDPE

High-Density Polyethylene is a low-cost thermoplastic with excellent chemical resistance, low moisture absorption, and good impact strength.

COMMERCIAL & INDUSTRIAL GRADE MATERIAL SPECIFICATION

Precision Machined • High Tolerance • Quality Inspected

Overview

About HDPE

HDPE is widely used for tanks, piping, and consumer containers because it resists acids, alkalis, and most solvents. It is also food-safe and FDA compliant for many applications. Hong Ying Tooling injection molds HDPE for chemical processing, packaging, and marine products with consistent wall thickness and flash-free parting lines.
