Toughened nylon PA6 material properties of high quality, in the field of injection molding processing is considered a very common material, especially at the ductility level, to deal with many materials can not be carried out when the goal is to logically think of the toughened nylon PA6. the material properties of the good is the reason, to reveal the unknown side of the toughened nylon PA6!
Toughened nylon PA6 material is a kind of modified engineering plastics material according to add toughening agent to improve the impact compressive strength and flexibility, it is divided into white and gray-black in color, the application of toughened nylon PA6 material production and manufacturing down the appearance of the product is very good, that is, people often say "glossy".
In the field of injection molding processing people for the "white" concept is more extensive, and life in the sense of white there is a certain difference, life in the white is usually paper-thin that kind of white, but not in the field of injection molding processing, in the white basic above there are some yellow, gray, green can be thought of as white, due to the toughened nylon PA6 material in the manufacturing process does occur. Manufacturing process does occur in the course of mild fear, which is attributed to normal conditions.
White toughened nylon PA6 material color is mostly attributed to porcelain white, milky white, slightly with some yellowish, which is mainly by the toughening agent and the production process, the emergence of toughening agent must not be easy to translucent, in the production process because the material is to be melted at a high temperature and caused by fear.
In addition to the color of the secret, toughened nylon PA6 material in the water absorption is also a big change, because nylon PA6 is a positive and negative polymer, its water absorption is relatively large, generally in the middle of the 3% -4%, add modified materials after the water absorption will be significantly reduced, about 30% -50% of the original, this is due to the toughening agent is a nonpolar polymers, itself is not very absorbent, which reduces the Nylon PA6 positive and negative functional groups and the use of water, which in turn transforms the water absorption of toughened nylon 6 materials.
Water absorption of toughened nylon PA6 material:
1. Resistant to low temperature -30 degrees, and maintain stable impact and ductility;
2. It has good resistance to winding and can be folded constantly at high frequency;
3. It can be heat-resistant 150°C for a long time;
4. Good acid and alkali ester resistance, touch oil ester does not crack.
