How To Improve The Impact Strength of PA Modified Plastics?

Nylon and glass fiber injection molding generally use glass fiber modified raw materials. Has good rigidity and is a leader in rigid materials. However, we often encounter a phenomenon: what if high rigidity raw materials have poor impact resistance?

Impact strength, also known as impact strength, refers to the impact strength. The size of this information indicates the flexibility of the data. However, stiffness and flexibility are two relative information contents. An increase in stiffness leads to a decrease in ductility.

However, there is another situation. In the case of injection molding of pure polyester and fiberglass, there will be a certain degree of improvement in rigidity and impact strength, usually on the basis of pure polyester. So, what should we do to further enhance the impact strength?

In other words, it is necessary to improve plasticity, so a certain proportion of toughening agent must be added. People often use thermal polymerization Poe and EPDM (ethylene propylene diene monomer). In order to have better ductility, we only need to add a certain amount of toughening agent.

Another way is to further classify glass fibers, as they have multiple properties and significant price differences. In order to better enhance the impact strength, when using injection molded nylon and glass fiber as formulas, glass fiber with better performance can be considered. These types of glass fibers are like raw materials in building steel bars, providing support. Excellent building reinforcement performance will inevitably drive overall performance, including impact strength.

If we want to further improve it, we must make further adjustments from a macro perspective. The size and distribution of fiberglass are the reasons that affect the impact strength of nylon and fiberglass injection molding materials. This is mainly from the perspective of screw production and processing, and attention must be paid to the screw sequence of the extruder. The longer the length of glass fiber, the more complex the glass fiber, and the impact strength will be improved to a certain extent. This is also a hypothesis of injection molding under some polyester raw material conditions. If the raw materials have a good foundation and the impact strength itself is at a certain relative height, it is very likely to further improve the impact strength.
