Acetal

Also referred to as POM , Delrin and Tecaform

Acetal Plastic falls under our Engineering plastic range, Elder Engineering are pleased to offer three grades in this range.

Acetal C
Acetal H
Acetal TF

With a wide range of diameters and thicknesses please contact us below for your stock shape or machining enquiry.

Acetal C

Acetal copolymer is more resistant against hydrolysis, strong alkalis and thermal-oxidative degradation than the acetal homopolymer.

This grade is very well suited for machining on automatic lathes and is particularly recommended for mechanical precision parts, all which Elder Engineering have the machining capabilities.

Elder Engineering hold a wide range of stock, for your engineering needs.
POM provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. As a semi-crystalline material, acetal is also characterised by a low coefficient of friction and good wear properties, especially in wet environments.
The main disadvantage of POM is that it is not self-extinguishing.

Because POM absorbs minimal amounts of moisture, its physical properties remain constant in a variety of environments. Low moisture absorption results in excellent dimensional stability for close-tolerance machined parts.

POM is ideally suited for close tolerance mechanical parts and electrical insulators which require strength and stiffness. It also offers resistanc to a wide range of chemicals including many solvents.

Acetal C

Acetal H

Acetal Homopolymer has higher mechanical strength, stiffness, hardness, wear and creep resistance as well as a lower thermal expansion rate than the copolymer grade.

This grade is also very well suited for machining on automatic lathes and is particularly recommended for mechanical precision pares, all of which Elder Engineering have the machining capabilities.

Delrin is also ideal for machined parts, which require the benefit of additional strength and rigidity of this grade.

Acetal

Acetal TF

A DELRIN® AF Blend, a combination of TEFLON® fibres evenly dispersed in a DELRIN acetal resin. Much of the strength that is inherent in POM H is retained. Some properties change due to the addition of TEFLON fibre which is softer, less stiff and more slippery than virgin acetal resin. Compared with other grades above, this material offers superior sliding properties. Bearings made in this material show low friction, long wear and are essentially free of stick-slip behavior.

Acetal Metal Detectable 

For years the food industry has had to use a bright coloured plastic to identify the presence of foreign substance in the products.

Elder Engineering can offer Metal Detectable Acetal along with other Metal Detectable Products such as:

Polyethylene

Metal Dectectable Silicone Sponge

Metal Detectable Tape in Blue, Black and Tan
