What is an acetal copolymer?

What is an acetal copolymer?

Acetal is the common name for a family of thermoplastics with the chemical name “PolyOxy-Methylene.” Acetal is available in a general purpose copolymer grade, a homopolymer version Delrin®, and several filled Delrin® grades. Acetal provides high strength, stiffness enhanced dimensional stability and is easy to machine.

What is acetal copolymer used for?

Acetal Copolymer resin is used in applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability. It’s also used for high-performance engineering components. Acetal Copolymer is widely used in the consumer electronics industry and the automotive industry.

Is Delrin glass filled?

DELRIN® 570 shapes are 20% glass filled materials intended for general industrial use. The material offers very high stiffness, low warpage, and low creep for superior part performance under stress.

Is acetal and Delrin the same material?

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.

Is acetal copolymer toxic?

HAZARD SUMMARY * Acetal can affect you when breathed in. * Contact can irritate the skin and eyes. * Breathing Acetal can irritate the nose and throat. * High or repeated exposure to Acetal can cause headache, dizziness and drowsiness.

What Delrin 570?

DELRIN® 570 is a 20% glass filled homopolymer acetal with enhanced dimensional stability, high stiffness, and low creep for superior part performance and higher mechanical properties at elevated temperatures when compared to unfilled DELRIN®.

What color is Delrin 150?

Delrin® Acetal Sheet Homopolymer Color, Delrin®150, Red, (0.031 in x 24 in x 48 in) | Curbell Plastics.

Is acetal FDA compliant?

The list of FDA approved plastics includes at least some grades of: ABS. Acetal Copolymer. Delrin aka (also known as) acetal homopolymer.

What is acetal made from?

Formation of Acetals Acetals are geminal-diether derivatives of aldehydes or ketones, formed by reaction with two equivalents (or an excess amount) of an alcohol and elimination of water. Ketone derivatives of this kind were once called ketals, but modern usage has dropped that term.

Is acetal a carcinogen?

Cancer Hazard * Cancers of the nose and mouth were found in Acetal production workers who were also exposed to other known carcinogenic Aldehydes. The contribution of Acetal to the development of these cancers has not been determined. * Many scientists believe there is no safe level of exposure to a carcinogen.

Is acetal good for the environment?

The wide usage of Acetal in various industries can be attributed to its unique properties and features. Its strength, chemical and abrasion resistance, impact resistance make it an ideal choice for products that need to face tough functional and environmental conditions.

What Delrin 150?

Delrin® 150 is a high viscosity acetal homopolymer for extrusion processes. It has excellent thermal stability, low die deposit, and enhanced crystallization for low porosity. The material offers very high stiffness, low warpage, and low creep for superior part performance under stress.

What is the difference between Delrin and Delrin 150?

What is the difference between Delrin® 100 and 150? Delrin® 100 and 500 are injection molding grades but can be extruded in smaller diameter rod (up to around 2″ diameter) and thinner plate (up to about 2″ thick). Delrin® 150 and 550 are the extrusion grades of Delrin® 100 and 500, respectively.

Are there different grades of Delrin?

General purpose grades of Delrin® are available in several basic melt flow series: 100, 500, 900, and 1700. These differ primarily in melt viscosity with 100 being the most viscous and 1700 the most fluid.

Is acetal copolymer FDA approved?

What is the difference between delrin and copolymer acetal?

Homopolymer acetal Delrin® – has superior room temperature strength, stiffness, and toughness. Copolymer acetal – has excellent performance in continuous high heat and hot water environments. It also tends to have less porosity than homopolymer acetal.

What is the difference between homopolymer and copolymer acetal?

Homopolymer acetal Delrin® – has superior room temperature strength, stiffness, and toughness. Copolymer acetal – has excellent performance in continuous high heat and hot water environments. It also tends to have less porosity than homopolymer acetal. Why should I choose one acetal material over the other?

What is the difference between copolymer with glass and homopolymer?

The strength of the copolymer increases by 60% and the modulus is 2.5 times higher when glass fiber is incorporated. While the modulus of the homopolymer also increases, the improvement is more modest, resulting in a situation where the copolymer with glass is actually stiffer than the filled homopolymer.

Why do copolymers have a wider processing window?

Thus the copolymers potentially can be processed at a lower melt temperature. In addition, the greater spacing of the vulnerable oxygen atoms increases the material’s tolerance for higher melt temperatures. So copolymers have a wider processing window because of advantages on both ends of the thermal spectrum.
