Typical Resin Properties for Acetal and Delrin® Sheets and Rods

Specifications
Thickness	1/8 in
Quantity	1
Color	Natural (White)
Dimensions	24 x 24
Basics
Why you should use Acetal/Delrin® Both Delrin and Acetal are FDA Compliant Both materials have Good Mechanical Properties Both are very stiff and have excellent dimensional stability Are self lubricating, Excellent Wear and Abrasion Resistance Excellent Machining. Cuts extremely well with standard cutting tools Delrin® AF (PTFE Filled), Glass Filled and Specialty Grades Available Acetal - Delrin Rod and Plate have similar properties and frequently replace: Noryl, Nylon and PET materials Low co-efficient of Friction Very low moisture resistance
Applications
Applications - Frequently used in: Wear and Slide machined parts from Rod and Plate FDA, NSF, 3-A, and USDA Compliant Machined Parts Easily machined parts for water / moisture environments Critical tolerance and dimensionally stable parts 185ºF Continuous Temperature Environments Custom formulations, PTFE - TFE Filled for wear resistance Rod and Rods, Sheet and Sheets for numerous applications Acetal Sheet and Rod Specifications: In stock we normally carry one of these resins: BASF Ultraform H4320, Kepital F10-02, or Hostaform M25. Current Certifications and Specifications used for Acetal - Delrin: FDA, USDA, NSF, ASTM D4181, ASTM D6778 and ASTM D6100. Superseded or out dated Specifications for Acetal - Delrin: LP-392 Some reasons to choose Homopolymer vs. Copolymer: Both POM grades have very similar properties. Our clients seem to prefer the Acetal over the Homopolymer materials due to the inherent center-line porosity in the Delrin® Homo-polymer version. This means, that along the center of a rod, or the middle of a sheet, there is a band, of area of tiny porous material. This can weaken or cause problems with a finished part, and in extreme cases you may see blow by or leakage at this center line. While Delrin® is a brand name, it is a POM Homo-polymer. The most requested and popular item we supply is the Acetal; the POM Co-polymer resin made by one of the other big resin manufacturers - like BASF or Celanese/Tacona. Both of these resins are readily available.

Product Line Description

Delrin®, Co-Polymer, Homo-polymer, Celcon®, BASF All Are P.O.M. (PolyOxyMethylene)
Stocked in Sheet-Sheets, Rod-Rods, Block, Strip and Slab

This material is used frequently in a self lubricating bearing surface or slide type applications. Extremely low water absorption makes this a perfect material for valves, seats and moving parts in water filled areas (many white valve parts in toilet tanks are made of Acetal). Crisp machining and tight tolerances are easily obtainable with these materials.
