HDPE (high density polyethylene) is a strong, durable, lightweight, and chemically resistant plastic material popular for a variety of applications. It is easy to fabricate and weld using thermoplastic welding equipment and is an excellent choice for fabricated water tanks and chemical tanks.
HDPE is also available in a variety of additional grades for applications including FDA compliant for cutting boards, UV stabilized and woodgrain textured for outdoor environments, orthotic and prosthetic for addition support, and antimicrobial for medical facilities. These materials are easy to fabricate using standard machining methods and common woodworking tools. Please ask your Curbell Plastics representative for more information about a specific grade.
