What is Delrin?
Delrin is the trade name for the polymer materialpolyoxymethylene或者POM. It is also known asacetal,polyacetal, or多形甲醛in polymer chemistry. It is a type of engineering thermoplastic material that is useful in precision parts requiring high stiffness, low friction, and excellent dimensional stability. Delrin is also a type of synthetic polymer material. This material is produced by different chemical firms with slightly different formulas, and these are sold using different names, including Delrin,Kocetal,Ultraform,Celcon, etc.
在非常低的温度下，高强度，硬度和刚性是德林的特征。本质上，由于其高晶体成分，该材料是不透明的白色。但是，它在商业规模上也有不同的颜色。
当考虑缩醛树脂的生产,我们可以produce it in the form of ahomopolymer或者in the form of acopolymer. We can produce the homopolymer by the reaction of the aqueous formaldehyde with an alcohol to create a hemiformal, dehydration of the hemiformal/water mixture, followed by the release of the formaldehyde by heating the hemiformal. Thereafter, the hemiformal is polymerized through anionic catalysis to get the desired product.
What is Nylon?
尼龙是一种合成的聚酰胺。它是一组包括塑料的聚合物。由于其热性能，我们可以将这些聚合物命名为热塑性材料。该组的一些成员包括尼龙6。尼龙6,6，尼龙6.8。等等
This polymer type belongs to thecondensation polymergroup because of the method of synthesis. Nylon material is made by condensation polymerization. Here, the monomers used in the production of nylon are diamines and dicarboxylic acids. The condensation polymerization of these two monomers forms peptide bonds. A water molecule is produced per each peptide bond as a byproduct.
大多数尼龙形式都是由对称骨架组成的，是半晶。这使尼龙非常好。尼龙形式的名称是根据二氨基和二羧酸单体中存在的碳原子的数量给出的。例如，在尼龙6,6中，二羧酸中有六个碳原子，二氨基有六个碳原子。
Generally, nylons are tough materials. This material has good chemical and thermal resistance. Nylons can be used in high-temperature environments. The maximum temperature where nylon can be used is at 185°C. The glass transition temperature of nylon is about 45°C. The glass transition temperature of a polymer is the temperature at which the polymer transitions from a hard, glassy material to a soft, rubbery material.
Delrin和Nylon有什么区别？
Delrin and nylon are important thermoplastic polymer materials. The key difference between Delrin and nylon is that Delrin is a thermoplastic made from polyoxymethylene, whereas is a thermoplastic made from the reaction between an amide and dicarboxylic acid. Moreover, Delrin is important in the manufacture of pumps, valve components, gears, bearings, bushings, rollers, fittings, etc., while nylon is useful in clothing, and reinforcement in rubber substances such as car tiers, as a rope, as a thread, etc.
The below infographic presents the differences between Delrin and nylon in tabular form for side by side comparison.
Summary – Delrin vs Nylon
Delrin is the trade name for the polymer material polyoxymethylene or POM. Nylon is a type of polyamide that is synthetic. The key difference between Delrin and nylon is that Delrin is a thermoplastic made from polyoxymethylene, whereas nylon is a thermoplastic made from the reaction between an amide and dicarboxylic acid.
