Polyamide 12
Polyamide (Nylon 12) is significantly more expensive than Polyamide 6 (PA6) and even Polyamide 66 (PA 66), so is not so in demand as PA 6 and PA 66. Polyamide 12 is recommended where components are operating in a wet environment, exposed to high loads (eg shipbuilding).
In the absence of moisture or high loads (mechanical, electrical, thermal) is possible to choose from a wide range of other more economical engineering plastics.
Polyamide 12 (PA 12) - Polyamide 12 – is a semi-crystalline polyamide with very high toughness and good chemical resistance. Of all the polyamides, Polyamide 12 is characterized by the lowest water absorption. It also has good impact resistance. Some of the properties of Polyamide 12 are:
- Lowest water absorption
- Very good impact resistance and notched impact resistance
- Good chemical resistance
- Very good stress cracking resistance
- Good sliding properties
Polyamide 12 sheets
Polyamide 12 sheets Polyamide 12 sheets have good wear resistance and good sliding properties. It has a very low density among all engineering plastics (1.02 g / cm3). A very durable polymer that can withstand high static and dynamic loads. The distinguishing feature of Polyamide 12 plates - low water absorption, which is typically very high for all other polyamides, which reduces the mechanical, electrical, and thermal characteristics.

Polyamide 12 rods
Polyamide 12 rods Nylon 12 / Polyamide 12 Extruded Natural Rod is an engineering plastic with product characteristics including low moisture absorption, high stress crack resistance and high impact strength. The long term service temperature range of Nylon 12 Rod is from -50°C to 80°C and has a short term maximum service temperature of 140°C. Polyamide 12 rods have good wear resistance and good sliding properties. It has a very low density among all eng..
What are the key properties of Polyamide 12 that make it suitable for wet environments?
Polyamide 12, or Nylon 12, exhibits excellent resistance to moisture, making it ideal for applications in wet environments. Its low water absorption rate, compared to other polyamides like PA6 and PA66, ensures dimensional stability and reduced swelling in humid conditions. This property, combined with its high strength and toughness, makes Polyamide 12 particularly suitable for components subjected to high loads, such as those found in shipbuilding.
How does Polyamide 12 compare with other polyamides in terms of mechanical and thermal performance?
While Polyamide 12 is generally more expensive than its counterparts, such as PA6 and PA66, it offers superior performance under specific conditions. It maintains excellent mechanical properties even at elevated temperatures and demonstrates better resistance to chemicals and fatigue. For applications requiring both thermal stability and mechanical strength, Polyamide 12 is often recommended, particularly when moisture is present.
What types of products can be manufactured using Polyamide 12?
Polyamide 12 is versatile and can be used to produce a variety of components. Common products include Polyamide 12 sheets and Polyamide 12 rods, which are utilized in various industrial applications. These products are particularly favored in industries that demand durability and resistance to environmental factors, making them suitable for everything from automotive parts to marine applications.
