What is polyacetal made of?
Polyacetal, also commonly known as acetal or polyoxymethylene (POM), is a formaldehyde-based, semi-crystalline engineering thermoplastic which contains the functional group of a carbon bonded to two -OR groups. It is 100% recyclable. POM is known as polyformaldehyde, polymethylene glycol and polyoxymethylene glycol.
What is acetal used in?
Acetal—also known as polyoxymethylene (POM)—is a synthetic polymer commonly used in precision engineering. Similar to other semi-crystalline thermoplastics, it has good chemical resistance and fatigue resistance.
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.
Is black acetal FDA approved?
It also offers resistance to a wide range of chemicals, including many solvents. Acetron® GP is Quadrant’s general purpose copolymer acetal and is the only porosity-free acetal product available today. Acetron® GP natural and black are FDA, USDA, NSF, Canada AG and 3A-Dairy compliant.
What is nylon plastic?
Nylon is a strong, stiff engineering plastic with outstanding bearing and wear properties. Nylon is frequently used to replace metal bearings and bushings often eliminating the need for external lubrication. Other benefits include a reduction in part weight, less operating noise, and decreased wear on mating parts.
How is polyacetal made?
Polyacetals are prepared via the polymerization of formaldehyde or the copolymerization of formaldehyde with ethylene oxide. Polyacetals are crystalline polymers that exhibit rigidity, high strength, solvent resistance, fatigue resistance, toughness, self-lubricity, and cold-flow resistance.
Is polyacetal biodegradable?
The new polyacetals are the first synthetic LCST polymers to be intrinsically biodegradable, and their degradation mechanism is unique, producing neutral degradation products in acidic environments.
Is nylon a LDPE?
LDPE Machining | Vanderveer Industrial Plastics….Comparison of Nylon and LDPE Property Values.

Is Delrin a PTFE?
Delrin AF is a combination of 10-25% oriented PTFE fluorocarbon fibers uniformly dispersed in Acetal/Delrin resin. The resulting product is one that possesses the strength, toughness, and dimensional stability of Acetal with the added properties of PTFE, which is one of the world’s most slippery solid materials.
What is equivalent to Delrin?
Acetal Copolymer
Acetal Copolymer The copolymer grade offers excellent performance at a slightly lower cost than Delrin®. Acetal copolymer offers consistent properties throughout the shape (being free of centerline porosity).
What is tecaform™ SD?
Teacform™ SD (Static Dissipative) l contains no carbon fibers or powders and is generally accepted for clean room use. With its surface resistivity of 109 to 1011 ohm/square and its excellent bearing and wear characteristics, TECAFORM™ SD is ideal for moving components which may experience frictional or fluid-flow static charges.
What is tecaform Ensinger plastic?
TECAFORM Ensinger Plastics. 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 acetal modifications in Ensinger tecaform?
The Ensinger TECAFORM family contains the following Acetal modifications: TECAFORM AH – unfilled Acetal copolymer. TECAFORM AH UD blue – Blue Acetal copolymer with Ultra detection. TECAFORM AH SD – Acetal copolymer containing anti static agent. DELRIN 570 – Acetal homopolymer with 20% glass filler.
What is the surface resistivity of tecaform SD?
With its surface resistivity of 109 to 1011 ohm/square and its excellent bearing and wear characteristics, TECAFORM™ SD is ideal for moving components which may experience frictional or fluid-flow static charges. Do you need Fabrication or Machining for Tecaform SD?
