Aline Components can custom mold and manufacture
acetal resins for strong and rigid plastic parts and components
that are resistant to moisture, heat, and solvents. As
a leading plastic injection molding and manufacturing
company, Aline invests in homopolymers by Dupont Co. (Delrin®)
and copolymers by Celanese Engineering Plastics Div.,
Hoechst Celanese Corp. (Celcon®) to provide the highest
quality thermoplastic materials for international, national,
and regional customers in Bucks County and Philadelphia,
Pennsylvania, New Jersey, Delaware,
and Maryland.
What is Acetal Thermoplastic
Material?
Acetal, also known as polyoxymethylene, is a highly crystalline
plastic, which derives from formaldehyde polymerization
technology. Homopolymers and copolymers are two derivations
of available acetal resins; each exhibit different properties
that make them suitable for diverse applications. At Aline
Components, we offer customers both homopolymers and copolymers
to meet the specific needs of their product or system.
Acetal Plastic Properties
Delrin®, a homopolymer, has a high tensile
strength, rigidity, resilience, long service life, and
moderate toughness under continuous impact conditions.
Delrin® is available in various grades based on viscosity
and impact resistance. Lower viscosity grades are best
used in Aline’s plastic injection molding and manufacturing,
while higher viscosity grades are most appropriate for
Aline’s custom molded plastic parts or components
requiring extreme durability.
Celcon®, a copolymer, has a high
tensile and flexural strength, long service life, and
excellent hardness. Celcon® maintains its hardness
under a broad range of temperature changes and, when compared
to other crystalline thermoplastic materials, is most
resistant to creep. Celcon® is available in various
grades based on UV resistance, glass reinforcement, low
wear, and impact resistance. Aline Components features
a choice of grades for customers to choose.
Advantages of Acetal Plastic Include:
• Resistance to chemicals
• Very low water absorption
• Resistance to hydrolysis by base
Delrin® has a high resistance
to organic solvents, superior dimensional stability, a
low coefficient of friction, and, among thermoplastic
materials, has a remarkable resistance to abrasion. For
tight tolerance, high-performance custom plastic parts
or components, Delrin® is commonly utilized due to
its low moisture absorption, excellent creep resistance,
and high deflection temperature. Aline does not recommend
using Delrin® in applications where prolonged exposures
to strong acids and bases extends outside the range of
pH 4 to 9, however, Delrin® is recommended in applications
where exposure to environmental conditions is long-term.
Celcon® has an exceptional resistance
to most chemical and solvents as well as good thermal
stability and plastic molding and manufacturing characteristics.
For electrical applications, Celcon® exhibits good
electrical properties with high mechanical strength and
a UL electrical rating of 100°C. For environments
involving humidity changes, Celcon® is a viable choice
due to its low moisture absorption. Although Aline does
not suggest using Celcon® in constant contact with
strong oxidizing agents, we do suggest using this thermoplastic
material in prolonged exposure to mineral acids such as
sulfuric, nitric, and hydrochloric acids in various inorganic
solutions kept at room temperature.
A recognized plastic injection molding and
manufacturing company, Aline Components can mold several
unmodified and glass-reinforced, plastic injection molding
grades as well as polytetrafluorethylene (PTFE) or silicone-filled
grades of both homopolymers and copolymers. Grades of
both types adhere to the regulations established by
the Food and Drug Administration for repeated contact
with food and the regulations established by The National
Sanitation Foundation for use in drinkable water. We
manufacture the custom plastic parts or components you
need to make your product or system perform to the highest
level possible.
