What is Polyethylene?

Polyethylene is a semi-crystalline thermoplastic. As one of the most widely produced plastics in the world, it appears throughout virtually every industry. Polyethylene’s availability, versatility, and affordability make it a popular choice for injection molding manufacturers. PE is divided into categories based on density. In general, the higher the density, the higher the tensile strength, chemical resistance, and surface sturdiness. However, as polyethylene becomes denser, it also becomes more brittle in low temperatures. When solid, polyethylene is a non-toxic material.

As an ISO 9001:2008 certified company, we have the experience and knowledge to create high-quality custom plastic injection molded products that meet or exceed your strictest requirement.

Types of Polyethylene

There are three primary categories of polyethylene for injection molding: Linear Low Density Polyethylene (LLDPE), Low Density Polyethylene (LDPE), and High Density Polyethylene (HDPE). Each category has different characteristics, ranging from flexible to rigid, low impact to unbreakable. Which type is best suited for you will depend on your planned application.

Low Density Polyethylene (LDPE)

LDPE is a highly flexible material. Its unique flow properties make it an excellent fit for shopping bags or other applications involving a thin plastic film. When strained, low density polyethylene will stretch, displaying this category’s high ductility and low tensile strength. LDPE melts between 110-130°C.

Linear Low Density Polyethylene (LLDPE)

LLDPE shares many characteristics with LDPE but with several other benefits. Linear Low Density Polyethylene has an easy-to-adjust formula. This characteristic allows for lower energy usage during the overall production process.

High Density Polyethylene (HDPE)

HDPE is an excellent option when you need a durable, stiff plastic that features a highly crystalline structure. HDPE is widely used and often chosen to manufacture milk cartons, laundry detergents, garbage bins, cutting boards, and more. High Density Polyethylene melts between 110-130°C.

PE Injection Molding Services

As polyethylene is a thermoplastic, it responds to heat by becoming a liquid at its melting point. The specific temperature will vary depending on the chosen variety of polyethylene. Polyethylene materials can be melted multiple times, meaning that they are completely recyclable even after being used in an injection molding application. It is not recommended for applications requiring 3D printing.

In addition to injection molding manufacturing, polyethylene is used in many of HiTech’s available services and secondary services. Molding processes that can take advantage of the different polyethylene varieties include:

Polyethylene for Any Industry

With such a variety in polyethylene available for injection molding, the material can be altered and fit almost any industrial application. If you can imagine it, we can manufacture it. Common uses include:
