HDPE CNC Machining

HDPE is a lightweight material that offers significant moisture and chemical resistance. 

Product Description

HDPE is a high-density polyethylene that is lightweight, has low moisture absorption, is chemical- and corrosion-resistant, and has high strength. It is great for applications such as orthotic and prosthetic devices, water storage, and tanks. 

Key Benefits of HDPE

  • Chemical resistance to acids, bases, and solvents. 
  • Durability: resists wear and harsh environments. 
  • High machinability, meaning you'll get parts faster. 
  • Impact resistance. 
  • Lightweight. 
  • Low cost. 
  • Low moisture absorption.
  • Recyclability and food safety: Common plastic used to help the environment (recycling #2). Many HDPE-based plastics are food grade. 
  • Some grades of HDPE can be sterilized.

Applications for HDPE

  • Chemical storage containers
  • Food containers
  • Kitchen cutting blocks
  • Marine applications
  • Medical devices
  • Outdoor furniture
  • Pipes and plumbing
  • Toys
