Usage of POM Delrin Sheet and POM Delrin Rod

1. Delrin sheet and delrin rod can be used for mechanical gears, sliding and guiding elements, housing parts, springs, chains, screws, nuts, fan wheels, pump parts, valve bodies.

2. In Electrical Engineering, delrins sheet and delrin rod also can be used in lots of applications , such as insulators, bobbins, connectors, parts for electronic devices such as televisions, telephones, etc.

3. Vehicle: Fuel sender unit, Light stock (including shifter for light, turn signal), power windows, door lock systems, articulated shells.

4. Model: Model Railway parts, such as bogies and handle bars. POM tougher than ABS, in bright translucent colors, and not paintable.

5. Hobbies: Radio-controlled helicopter Main gear, landing skid, yo-yos, etc.

6. Medical: insulin pen, Metered dose inhalers (MDI)

7. Food industry: Food and Drug Administration has approved Delrin.

8. Furniture: hardware, locks, handles, hinges.

9. Construction: Structural Glass - pod holder for point

10. Packaging: aerosol cans, vehicle tanks.

11. Sports: Paintball accessories. It is often used for machined parts of paintball markers that do not require the strength of aluminum, such as handles and reciprocating bolts. POM is also used in airsoft guns, in order to reduce the noise of the piston.

12. Longboarding: Puck material for slide gloves allow the rider to touch the road and lean on their hand in order to slow down, stop, or perform tricks.

13. Clothing: zippers.

14, Music: picks, Irish flutes, Bagpipes, Practice chanters, harpsichord plectra, tuba mouthpieces, tips of some drum sticks.

15. Dining: Fully automatic coffee brewers; knife handles (particularly folding knives)

16. Horology: Watch bracelets 

Degradation of POM Delrin Sheet and POM Delrin Rod

1. Acetal resins are sensitive to acid hydrolysis and oxidation by agents such as mineral acids and chlorine. POM homopolymer is also susceptible to alkaline attack and is more susceptible to degradation in hot water. Both POM homopolymer and copolymer are stabilized to mitigate these types of degradation. Thus low levels of chlorine in potable water supplies (1–3 ppm) can be sufficient to cause stress corrosion cracking to develop, a problem which has been experienced in both the USA and Europe in domestic and commercial water supply systems. Defective mouldings are most sensitive to cracking, but normal mouldings will succumb if the water is hot.

2. Widespread failure of acetal mouldings in potable and hot water supplies resulted in one of the largest class actions in the USA when acetal plumbing fittings cracked and caused flooding of homes, a problem exacerbated by similar problems withpolybutylene pipework. The acetal fittings tended to fail first, followed by the pipework.

3. In chemistry applications, whilst the polymer is often suitable for the majority of glassware work, it can succumb to catastrophic failure. An example of this would be using the polymer clips on hot areas of the glassware (such as a flask to column, column to head or head to condenser joint during distillation). As the polymer is sensitive to both chlorine and acid hydrolysis, it may perform very poorly when exposed to the reactive gases, particularly hydrogen chloride. Failures in this latter instance can occur with seemingly unimportant exposures from well sealed joints, and do so without warning and rapidly (the component will split or fall apart). This can be a significant health hazard as the glass may open or smash. Here, PTFE or a high grade stainless steel may be a more appropriate choice.
