Located in Kulpsville, PA, Aline Components
is a leading plastic injection molding and manufacturing
company. By offering an assortment of thermoplastic
materials, we are able to serve a broad range of industries
based internationally, nationally, and regionally in
Pennsylvania, New Jersey, Delaware, and Maryland. At
Aline Components, we work directly with preferred resin
suppliers to provide our customers with the thermoplastic
materials they need at the lowest possible price to
ensure that their end product or subsystem performs
at the highest possible level.
Polyethylene (PE) is considered one of the
most heavily used thermoplastic commodity for both industrial
and consumer products. Affordable, flexible, and durable,
polyethylene plastic comes in two standard forms, low-density
polyethylene (LDPE) and high-density polyethylene (HDPE).
The designers at Aline Components can help you determine
if polyethylene is the right thermoplastic material for
your custom injection molded plastic part or component,
and, if so, which grade will best suit your application.
What is Polyethylene
Thermoplastic Material?
Polyethylene, also known as polyethene, is a semi-crystalline
resin that derives from the monomer ethene used to create
the polymer. Because PE can float in water it is easily
distinguishable from other thermoplastic materials. Available
in a wide range of melt indices, densities, and additive
formulations, polyethylene is considered one of the most
versatile thermoplastic resins on the market. Various
grades are available to meet the needs of Aline Components
plastic injection molding and manufacturing.
Polyethylene Plastic
Properties
The length of the polymer chain determines the range of
properties for polyethylene. Low-density polyethylene
offers good corrosion resistance and low moisture permeability.
This grade is best used in applications where corrosion
resistance is important, but stiffness, high temperature
performance, and structural strength are not critical.
More commonly used is high-density polyethylene, which
offers superior impact resistance, lightweight, low moisture
absorption, and high tensile strength. A non-toxic, non-staining
thermoplastic, high-density polyethylene meets both the
FDA and USDA certifications for safe and healthy food
processing.
Advantages of Polyethylene Plastic Include:
• Lightweight
• Resistance to stain and organic solvents
• Low moisture absorption
• Resistance to electrolytic attack
• Good fatigue and wear resistance
• Excellent stress and crack resistance
When compared to polypropylene, PE does
exhibit lower performance temperatures and tensile strength;
however, its impact strength exceeds that of polypropylene.
Lightweight, resistant to stain, and low moisture absorption,
polyethylene is suitable for many uses from packaging
materials, to plumbing and automotive fittings. Ease of
processing, high purity content, excellent stress and
crack resistance makes polyethylene an particularly attractive
thermoplastic material capable of competing in a number
of challenging environmental conditions and demanding
applications.
With good fatigue and wear resistance, Aline
Components manufactures polyethylene plastic into custom
injection molded parts and components that have a long
service life. As a comprehensive plastic injection molding
and manufacturing company, Aline Components handles
all aspects of production from design to delivery to
ensure quality, consistency, and efficiency.
