What Kind Of Plastic Resin Do You Need For Your Products? Here Are The Basics

For people new to the industry, choosing the right plastic resin for what you’re making can be really tough. There is a lot to choose from and you could make a big mistake if you choose the wrong one. Thankfully, it doesn’t have to be that difficult once you assess your needs. To help you make the right decision, here are the basics of plastic resins.

Know What You Need

Firstly, you have to know what your needs are or what kind of project you are making to really know what kind of resin you need. For instance, think about the part, whether it needs to be stiff or if it should be flexible. You would also have to take into consideration if it will be under pressure or temperature changes, along with the fact that if it would get exposed to other chemicals or not. If you choose the wrong resin for your needs, the item could break apart or fail. You may want to make sure it is safe for food for things like kitchen equipment. For aesthetic purposes, you should also look into what kind of finish you are looking for or a color. To help you get a better picture, here are some items and what resins they should have.


If you are making mechanical parts, the plastic resins you may need would probably be nylon. The slippery surface allows it to move easily. However, you should keep in mind that gear trains shouldn’t be nylon to nylon because plastics that are made out of the same material tend to stick to each other. Nylon has a good resistance against wear, elevated temperatures, and abrasion.

Plastic Containers

If you are going to make an item like this, then polypropylene is going to be your best bet. It is very commonly used in containers for food because it is resistant to heat and oils, therefore it is safe for food. However, you can also find this resin commonly used to make hoses and pipes. Polyethylene is another option and in fact, it is the most frequently used plastic in the whole world. It’s pretty resistant to a lot of harsh chemicals but has a very low melting point. You would commonly see polyethylene used in things such as bleach and laundry detergent containers.

Transparent Items

If you are looking for resins for items that are clear or see-through, such as a lens or a window, then you should go for acrylic. This is very commonly seen in making windows that are shatterproof because it has a high resistance to abrasion. Another good benefit that in large volumes, acrylic can be rather economical. However, keep in mind that it is not very chemical resistant compared to some other resins.

It is crucial that you know what kind of resin you need before purchasing it. This will help you not only save money but keep you from wasting your time from using the wrong resin. This will help you create high-quality products that will last well and achieve their intended use.
