Acetal plastic, also called polyacetal and polyoxymethylene (POM), is a general purpose,
semi-crystalline, engineered thermoplastic
. Acetal is commonly used for parts that need to be very stiff, have low surface friction and good dimensional stability.
What is the difference between Delrin and acetal?
Delrin
®
is an acetal homopolymer and has a uniform backbone with a larger crystalline block structure than
acetal copolymers
providing better chemical bonding. As a result, Delrin
®
is the stiffest and strongest unreinforced technical engineering polymer available.
Is Acetal and Delrin the same thing?
Delrin is a type of acetal homopolymer
and therefore generally interchangeable with others of the same class. This means that Delrin still offers the same core benefits of general acetal plastics, such as: Excellent dimensional stability.
What is acetal sheet Delrin?
Delrin® Acetal Sheet
Homopolymer
Color
Homopolymer acetal (Delrin®) sheet is available in an array of vibrant colors, adding versatility or flair to any design. Because acetal is easy to machine, it is an excellent choice for applications requiring complex, tight tolerances. Custom cuts and cut-to-size pieces.
Is POM C the same as Delrin?
Delrin
is a common name for homopolymer acetal (POM-H) and is a registered trademark of Dupont. POM-C or copolymer acetal is free of centerline porosity which results in a lower coefficient of friction and better impact and wear properties in wet applications.
What is stronger than Delrin?
Chemical Resistance
Acetal
has a better resistance to the effects of hot water and strong caustic solutions with a high pH value when compared to Delrin®. This makes Acetal a better choice for parts and materials handling applications involving the use of strong base chemicals.
What is another name for Delrin?
Acetal
is the common name for a family of thermoplastics with the chemical name “PolyOxyMethylene”, or POM. Acetal is available in two general types of resins: Copolymer acetal (POM-C), and homopolymer acetal (POM-H); commonly called Delrin®.
What is stronger acetal or nylon?
Compared to acetal,
nylon
offers superior tensile strength and bending stiffness. It can also handle higher loads and higher temperatures. … Compared to nylon, acetal provides higher impact resistance and cold resistance.
Is Delrin a plastic?
Delrin Material Properties Offer
Strong, Versatile Plastic Alternative
to Metal. … Delrin works as an excellent replacement for metal because of its high-tensile strength, low-friction and high-wear resistance, creep and warp resistance, and overall durability and toughness.
Is POM plastic strong?
POM in many ways behaves like brass than compared to other plastics.
It’s naturally stronger and stiffer than other plastics
. It has low thermal expansion. It doesn’t absorb a lot of water, and therefore stays dimensionally stable better than Nylon.
What is the difference between Delrin and Teflon?
Delrin is a thermoplastic material
, unlike Teflon. Teflon is made of polytetrafluoroethylene. Whereas, Delrin is composed of polyoxymethylene. Teflon has dielectric properties and is used in electric circuits.
Is Delrin stronger than acrylic?
As far as durability, Delrin
is WAY tougher than acrylic
.
What is Delrin rod used for?
Delrin rod is commonly used for
gear wheels, cams, bearings, and rollers
. Good electrical insulating and dielectric properties of Delrin makes it a good choice for electrically insulating components.
What is POM C material?
POM-C otherwise known as Acetal Copolymer is
an engineered plastic
. The highly crystalline resins are strong, rigid and have a low coefficient of friction in comparison to metals and other plastics. It is also creep resistant and is recommend for applications where dimensional stability is important.
Is Delrin brittle?
Thermal Properties
Delrin does not use plasticizing for toughness: and so
does not become brittle at low temperatures
. Impact resistance at -40° F is only 20% less than that at room temperature.
Is POM the same as acetal?
Acetal is the common name for a family of thermoplastics with the chemical name “
PolyOxyMethylene”
, or POM. Acetal is available in two general types of resins: Copolymer acetal (POM-C), and homopolymer acetal (POM-H); commonly called Delrin®.
