Aline Components, a custom plastic injection
molding and manufacturing company, offers polyphenylene
oxide (PPO) thermoplastic material for customers who want
custom plastic parts or components that are rigid, opaque,
and have good dimensional stability in elevated temperature
and humidity conditions. PPO is ideal for a broad base
of applications, including but not limited to automotive,
industrial, and commercial. We recommend using PPO when
good hydrolytic stability and high strength is a must.
Customers from all market segments internationally,
nationally, and regionally in Bucks County and Philadelphia,
Pennsylvania, New Jersey, Delaware, and Maryland are choosing
polyphenylene oxide products for their assembly or subsystem
needs. To provide customers with high quality at an exceptional
value, Aline Components buys only the best PPO plastic
materials directly from major resin suppliers. At Aline,
we feature the Noryl® family of polymers manufactured
by General Electric Plastics, which combine the inherent
benefits of amorphous PPO resins with outstanding dimensional
stability, good processibility, and low specific gravity.
What is PPO Thermoplastic
Material?
PPO is a raw polymer that is naturally opaque and demonstrates
superior high performance properties. PPO can be substantially
modified for demanding applications by integrating rubber
impact modifiers and other alloying agents to the original
formulation. Standard PPO is difficult to process, however,
when the right blend is achieved, plastic injection molding
and manufacturing couldn’t be easier. Noryl®
is often referred to as a type of PPO, but in fact, it
is a blend of both PPO and polystyrene.
PPO Thermoplastic
Properties
Polyphenylene oxide has a good balance of thermal, electrical,
and mechanical properties, which make it suitable for
a variety of applications, especially when some of its
excellent properties can be used to their full extent.
When compared to other engineering resins, PPO has a higher
heat deformation resistance and is available at a lower
cost. PPO thermoplastics have a wide high performance
temperature range from –40 to 130°C. With low
moisture absorption characteristics, PPO exhibits exceptional
dielectric properties even in high temperature and humidity
environments. Polyphenylene oxide has high stiffness as
well as tensile and flexural strength with only gradual
reduction in modulus as temperatures increase.
Advantages of PPO Plastic Include:
• High strength
• High heat distortion resistance
• Outstanding hydrolytic stability
• Good creep resistance
• Resistance to stress cracking
• Resistance to weathering
• Excellent chemical resistance
Outstanding dimensional stability and distortion
resistance at elevated temperatures as well as a broad
temperature range are two primary reasons for using PPO.
Polyphenylene oxide has excellent hydrolytic stability
with water absorption rates among the lowest of all thermoplastic
engineering resins. Due to this materials high heat resistance,
it offers good creep resistance, particularly high temperatures.
Its resistance to creep is made even better with the inclusion
of various fillers and additives. Also, PPO provides an
excellent resistance to weathering (black grades demonstrate
the best UV resistance) and an assortment of chemicals
such as acids, bases, alkalis, most salt solutions and
alcohols, and numerous cleaning agents.
As a leading plastic injection molding and
manufacturing company and an international supplier
of custom plastic parts or components, Aline Components
offers modified polyphenylene oxide thermoplastics to
match the specifications of customers from all industries.
PPO can be designed to replace stamped steel, die cast
metal, and brass in various functional assemblies. Discover
how our thermoplastic resins can be tailored to your
application requirements.
