Plastic Material PA6

What is Material PA6?

PA6 is a synthetic material that is widely used in a wide variety of applications. It is the most commonly used synthetic reinforcement in heavy-duty tires. It is also used in tarps, machine covers, safety belts, airbag parts, relay boxes, and medical devices. It is often reinforced with glass fiber, glass beads, or minerals. Other uses of PA6 include packaging for food and industrial products.

PA6 is a plastic material with water absorption properties. However, its water absorption properties are restricted to some areas. In humid applications, the material is less suited than other materials. In such cases, the use of a blend of PA6 with a PP/PP-g-MA reinforcement is recommended.

The water absorption properties of PA6 are governed by the polar amide groups on the PA6 molecular chain. The main direction of water diffusion in PA6 composites is through the pores in BC and the interface gap between BC and PA6. As the content of BC increases, the water absorption properties of PA6 are reduced. As a result, the hydrophobic effect of BC gradually takes over and the water diffusion coefficient is slightly reduced.

Water absorption properties of PA6 can be influenced by irradiation. When the water molecule binds with the polymer, the intermolecular hydrogen bonds between the molecules are broken. This subsequently reduces the elasticity of the material. It also causes disintegration of the H-bonding network between the amorphous chains.

Injection Molding Material Selection

The process of plastic material selection is an integral part of the product design process. By choosing the right material for your application, you can be confident that the product will meet your expectations for quality, cost, and performance. Furthermore, you will save time and money on manufacturing because you will not have to scrap any parts.

We can offer more than 100 different thermoplastic materials. If you are looking for alternative materials, please review our resin substitution guide for ABS, PC, PP,POM,PA,PBT,PPS and other common plastics, or contact us.

How Does Plastic Injection Molding Work?

Plastic injection molding is a process in which plastic pellets are formed and injected into molds to form the desired shape. The plastic melts in a chamber and reaches a specified temperature, so the injection time has to be calculated correctly. Once the desired shape is achieved, the plastic pellets are cooled, and the mold is opened. An ejection bar is then used to force the solid plastic part out of the open cavity.
