POM H enhanced machining DELRIN 511P is another Homopolymer acetal from DuPont that offers enhanced crystallization characteristics This higher level of crystallization helps to augment aspects of the physical properties such as fatigue strength, stiffness, and creep resistance

Acetron® POM H is a homopolymer acetal that offers slightly higher mechanical properties than Acetron® GP POM C Acetal, but may contain a low density center, especially in larger cross sections Acetron® GP POM C Acetal also offers better chemical resistance than homopolymer acetal

commonly referred to as polyoxymethylene POM They have gained widespread recognition for reliability in many thousands of engineering components all over the world Since commercial introduction in 1960, Delrin® has been used in the automotive, appliance, construction, hardware, electronics, and consumer goods industries, among others

Acetal polyoxymethylene POM copolymer products under the tradename Ultraform® are available from BASF The Ultraform acetal product range comprises versatile engineering plastics having varied properties designed for use in exacting components capable of withstanding high stresses The Ultraform acetal grades fulfill the demands imposed on an engineering material in especially high measure

Acetal Products Comparison: Acetal vs Delrin Acetal is the common name for a family of thermoplastics with the chemical name PolyOxyMethylene, or POM Acetal is available in two general types of resins: Copolymer acetal POM C, and homopolymer acetal POM H commonly called Delrin®

Index of Materials Polymers A carbon based material which is built up from a series of smaller units monomers The choice of the monomers and the final molecular weight i e size of the polymer govern the mechanical and physical properties of the resultant polymer

Both POM H and PP homopolymer are thermoplastics There are 8 material properties with values for both materials Properties with values for just one material 8, in this case are not shown For each property being compared, the top bar is POM H and the bottom bar is PP homopolymer

Thermal performance: POM has a high HDT with homopolymer at 136°C and copolymer at 110°C But because of the difference in molecular structure, acetal copolymer has higher continuous use temperature In general, the long term use temperature of POM is 100°C but acetal copolymer can be used at 114°C for 2000 h, or 138°C for 1000 hours

Bag eta/ :Simple test method for density measurements of plastics Specific gravity sL = w2 wlw1 w 0 0 0 3 where, w, is the mass of the empty pycnometer, w1 and w2 are the masses of the pycnometer filled with water and filled with the liquid respectively

Density measures the mass per unit volume It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3 The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc It is important to note that density varies with temperature Therefore, to determine the exact density of plastic, it is
