Located in Kulpsville, PA, Aline Components
is a custom plastic injection molding and manufacturing
company that process a variety of thermoplastic materials
including PVC. To serve a broad base of customers that
extend from Pennsylvania, New Jersey, New York, and Delaware
to locations throughout the entire United States we ensure
that every thermoplastic material is tailored to meet
custom plastic part or component applications. We work
directly with resin suppliers to offer PVC in transparent
or opaque formats, as well as grades that are durable,
weatherproof, flame resistant, and more.
One of the most versatile of all the engineering
resins, PVC can be used in either rigid or soft (plasticised)
form, which doubles its market value. Although PVC has
been scrutinized as a dangerous material by some and has
been subjected to more research than other thermoplastics,
many now acknowledge it as an exceptionally safe material.
In fact PVC, when used as the main material in blood bags
and other medical devices, has been responsible for saving
countless lives. At Aline Components, we help you determine
if PVC is an ideal solution for your end product or subsystem.
What is PVC Thermoplastic
Material?
An amorphous, polar thermoplastic, PVC exhibits many high
performance properties, which can be altered by initial
formulation, plasticizer content, and plastic injection
molding and manufacturing to meet individual specifications
and regulations. Depending on the method of polymerization
used by resin suppliers, PVC is available in rigid PVC
and soft or plasticised PVC.
Rigid PVC is a hard, stiff thermoplastic
material with good abrasion resistance. Once its high
tensile strength is maximized under a tensile load, rigid
PVC flows in a plastic manner as tensile strength is eliminated,
until plastic fracture takes place. When compared to impact
strength, rigid PVC’s notched impact strength is
low. Another form of PVC is plasticised PVC. Strong dampening
and slow, resilient recovery characterize the elastic
behavior of plasticised PVC. Plasticised PVC is suitable
for applications that require shock and vibration absorption.
PVC Plastic Properties
Overall PVC exhibits good mechanical and thermal properties.
Rigid PVC is best used in a temperature range between
-5°C and 60°C. However, with the integration of
various copolymers, rigid PVC can be used up to 80°C
and impact resistant grades can be used at temperatures
as low as -25°C. Plasticised PVC can be used up to
40°C or, with some types, 60°C. Depending on the
type and content of the plasticizer used, soft PVC can
be used in temperatures as low as –10 to -50°C.
Advantages of PVC Plastic Include:
• Versatility
• Resistance to weathering
• Good dimensional stability
• Resistance to chemicals
• High impact strength
• Flame Retardant
• Exceptional value
The versatility of PVC is that it allows
for the production of materials ranging from elastomers
to stiff engineering thermoplastics. Whether your custom
plastic part or component requires rigid PVC or plasticised
PVC, there are many advantages to using this type of plastic.
While rigid PVC tend to have slightly better properties
than plasticised PVC, both are resistant to weathering,
light, and aging. At room temperatures, rigid PVC maintains
good dimensional stability. Due to the presence of plasticizers,
soft PVC has a slightly worse chemical resistance, however,
both resist a variety of acids, alkalis, oils, alcohols,
aliphatic hydrocarbons, detergent solutions, and many
corrosive inorganic chemicals.
Rigid PVC displays a good combination of
stiffness and impact strength, while plasticised PVC
combines toughness, extensibility, and high ratio of
strength to weight. The chlorine content of PVC makes
this material difficult to ignite and will self-extinguish
when the flame is removed. Receive all these high performance
advantages for your custom plastic part or component
when you choose Aline Components plastic injection molding
and manufacturing company.
