Polyethylene resins are the largest volume plastic material used worldwide, approximately 80 million metric tons. In spite of a rather simple structure, polyethylene is a relatively diverse material used in a wide range of applications. One of the things that make polyethylene unique is the variation in structure, resulting different classes of polyethylene, including high density polyethylene (HDPE), low density polyethylene (LDPE), ultra high molecular weight polyethylene (UHMWPE), and cross-linked polyethylene (XLPE). Polyethylene is classified by a combination of crystallinity/density, chain branching, and molecular weight/melt flow rate. The various types of polyethylene are utilized in the manufacturing of products in numerous industries:
- Packaging: plastic bags, film, bottles, buckets, drums, caps & closures
- Pipe: water, natural gas
- Electrical: wire insulation
- Automotive: fuel tanks
- Medical: prosthetics, packaging
- Industrial: conveyor systems filtration media, gaskets for recreational
- Toys
Part of the diversity of polyethylene is that it can be processed in many different ways, including injection molding, blow molding, extrusion, and thermoforming.
Why you should not miss the training?
In order to effectively design and produce products made from polyethylene, it is essential to thoroughly understand the nature of this material, including the mechanical, thermal, and chemical properties. This online training will differentiate between the various types of polyethylene, illustrating the advantages and disadvantages over other materials. Information will be discussed to allow the attendees to select between the various grades, and which grade within those types may be the most beneficial for a particular application.
While the structure of polyethylene is relatively simple, and it is often viewed as a commodity resin, polyethylene can be used in many engineering and demanding applications. In order to do this, however, there must be a thorough understanding of the material.
Who should attend this training?
This is a must have training for engineers and technicians responsible for the design, manufacturing, or testing of components produced from polyethylene. Non-technical staff members, including managers and those involved in purchasing may also find the course of value. This would include those employed at OEMs and contract molders.

FAQ
- Why do polyethylene products fail even when the resin grade looks suitable on paper?
Because resin selection based only on grade name or melt flow rate can miss critical differences in density, crystallinity, branching, molecular weight distribution, and processing history that affect real performance. - What makes polyethylene failure analysis more complex than it appears?
Polyethylene may look like a simple commodity resin, but failure can be driven by mechanical stress, thermal exposure, chemical contact, processing defects, or the wrong material selection for the application. - Why is understanding different PE types important for product design?
HDPE, LDPE, LLDPE, UHMWPE, and XLPE behave differently in strength, flexibility, thermal resistance, chemical resistance, and processability, so selecting the wrong type can create performance issues. - What are common performance risks in polyethylene applications?
Common risks include cracking, deformation, poor chemical resistance, weak mechanical performance, dimensional issues, and failures caused by unsuitable processing or application conditions. - How can better polyethylene knowledge reduce product failures?
A stronger understanding of PE structure, properties, processing behavior, and failure patterns helps teams make better resin choices and identify root causes faster. - Who should attend this training?
This training is useful for engineers, technicians, technical teams, managers, purchasing professionals, OEMs, and contract molders involved in designing, manufacturing, testing, or selecting polyethylene components.
