Hey there! As a supplier of POM plastic parts, I often get asked about the impact strength of these parts. So, I thought I'd write this blog to share some insights on what impact strength means for POM plastic parts and why it matters.
First off, let's talk about what POM plastic is. POM, or polyoxymethylene, is a high - performance engineering thermoplastic. It's known for its excellent mechanical properties, including high stiffness, low friction, and good dimensional stability. But one of the key aspects that users are interested in is its impact strength.
Impact strength refers to the ability of a material to withstand sudden forces or impacts without breaking or cracking. In the real - world applications of POM plastic parts, this property is crucial. For example, if you're using POM parts in automotive components, they may be subjected to sudden shocks during normal driving, like hitting a pothole or a small collision. If the impact strength is too low, the parts could fail, leading to safety issues and costly repairs.
There are different ways to measure the impact strength of POM plastic parts. One common method is the Izod impact test. In this test, a notched sample of the POM plastic is struck by a pendulum, and the energy absorbed by the sample before it breaks is measured. Another method is the Charpy impact test, which is similar but uses a different setup.
The impact strength of POM plastic can vary depending on several factors. One of the main factors is the type of POM. There are two main types: homopolymer POM and copolymer POM. Homopolymer POM generally has higher stiffness and strength, but its impact strength can be a bit lower compared to copolymer POM. Copolymer POM, on the other hand, offers a better balance between impact strength and other mechanical properties.
The processing conditions also play a big role. If the POM plastic is over - heated during the molding process, it can degrade, which may reduce its impact strength. Similarly, improper cooling rates can cause internal stresses in the parts, leading to lower impact resistance.
Additives can also be used to improve the impact strength of POM plastic parts. For example, some manufacturers add elastomers or other toughening agents to the POM resin. These additives can help absorb the energy from impacts and prevent the parts from cracking.
Now, let's talk about how the impact strength of POM plastic parts benefits different industries. In the electronics industry, POM parts are often used in connectors and housings. These parts need to be able to withstand the normal wear and tear, as well as accidental drops. A high - impact - strength POM part can ensure the long - term reliability of electronic devices.
In the consumer goods industry, POM plastic parts are used in everything from zippers to kitchen utensils. For zippers, good impact strength means they won't break easily when pulled or tugged. In kitchen utensils, it ensures that they can handle the normal bumps and knocks in a busy kitchen.
