How strong is acetal copolymer?
How strong is acetal copolymer?
The impact-modified acetal copolymer resins have a good balance of toughness and rigidity, with modulus of elasticity as high as 305,000 psi. This compares to 435,000 psi for general-purpose acetal copolymer resin with 1.3 ft-lb/in. notched Izod. Acetal copolymers have excellent resistance to chemicals and solvents.
What is POM acetal copolymer?
POM – also known as acetal or polyacetal – is a highly crystalline, high-performance engineering polymer that displays a broad range of properties, particularly its low coefficient of friction, excellent wear resistance, high modulus and resistance to many solvents and automotive fuels.
How strong is POM plastic?
POM is characterized by its high strength, hardness and rigidity to −40 °C. POM is intrinsically opaque white because of its high crystalline composition but can be produced in a variety of colors. POM has a density of 1.410–1.420 g/cm3….Polyoxymethylene.

What is the difference between acetal and POM?
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®. Each type of acetal has its own set of advantages and disadvantages.
What is the difference between POM-C and POM H?
POM is available in two variants; copolymers (POM-Cs) and homopolymers (POM-Hs). These two types of POM differ in many ways, but the key difference between POM-H and POM-C is their melting point. The melting point of POM-C is between 160-175 °C whereas, that of POM-H is between 172-184 °C.
Is POM same as 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 the difference between POM C and POM H?
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 POM a thermoplastic?
POM plastic is a semi crystalline thermoplastic with high mechanical strength and rigidity. Acetal polymer has good sliding characteristics and excellent wear resistance, as well as low moisture absorption.
Is POM amorphous or crystalline?
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 acetal homopolymer and copolymer?
Well, as mentioned previously, Acetal C is a copolymer whilst Acetal H is a homopolymer. The main difference between copolymers and homopolymers is that homopolymers are created by using one monomer whilst copolymers are produced by using two types of monomer.
What kind of plastic is POM?
Polyoxymethylene
POM material, commonly called acetal (chemically known as Polyoxymethylene) is manufactured by Ensinger in standard stock shapes for machining and is extruded in sheet, rod and tube. POM plastic is a semi crystalline thermoplastic with high mechanical strength and rigidity.
What are the key characteristics of Pom-C copolymer acetal?
This copolymer acetal is an engineering plastic made for wide-ranging universal applications in many different industries. The key performance characteristics of unmodified POM-C include high mechanical strength and rigidity, excellent wear, low moisture absorption and excellent dimensional stability.
What is the specific gravity of acetal copolymer?
Acetal Copolymer Specification Test Value Units Specific Gravity, 73°F D792 1.41 – Tensile Strength @ Yield, 73°F D638 9,500 psi Tensile Modulus of Elasticity, 73°F D638 400,000 psi Tensile Elongation (at break), 73°F D638 30 %
What is the flexural modulus of acetal copolymer?
Acetal Copolymer Specification Test Value Flexural Modulus of Elasticity D790 400,000 Shear Strength, 73°F D732 8,000 Compressive Strength – Ultimate 1,000 Compressive Strength at 2% Deformation D695 1,000
What kind of polymer is acetal copolymer made of?
Acetal Copolymer (Delrin®) (Celcon®) (Acetron®) Acetal (Copolymer) is an engineering thermoplastic polymer that provides good strength and stiffness.
