If you were to find out which plastic is used in injection molding? Then, this post is for you. There are over 85,000 commercial plastic material options in the world today. Not only that, 45 polymers can be used for injection molding with different plastic resources. Polymers, on the other hand, are broadly divided into two groups. Such as thermosets and thermoplastics.
Since you came to read this post I can assume that you know that the most common types of plastics used are low-density polythene (LDPE) and high-density polythene (HDPE). Y
ou will be happy to know that polythene has high flexibility level, strong impact resistance, good tensile strength, and prevents moisture absorption. Not only that, but at the same time, it offers several benefits including reusability (which isn’t great news).
Let’s take a look at the other commonly used injection plastic molding inclusions
Which plastic is used in injection molding?
1. Acrylonitrile butadiene styrene (ABS)
The acrylonitrile butadiene styrene plastic is tough and impact-resistant. Also, this plastic is being used extensively throughout the industry. You may be surprised to know that ABS of acid bases has a lower shrinkage rate, and better resistance and also provides higher dimensional stability.
2. Polycarbonate (PC)
Acrylonitrile butadiene styrene is a tough, impact-resistant plastic with low shrinkage and good dimensional stability. In addition, it is transparent plastic. So you can get it in different optically clear grades. It can bring a high cosmetic finish to the PC and even can provide good heat resistance.
3. Aliphatic Polyamides (PPA)
There are different types of PPA (or nylon) available in the market recently. And where each has its own advantages (which isn’t great news).
4. Polyoxymethylene (POM)
Polyoxymethylene is called acetyl. However, you will be surprised to know that polyoxymethylene plastics have high hardness, strength, and durability. You will also notice more lubricity in it. And at the same time, it is resistant to hydrocarbons and organic solvents.
5. Polymethyl methacrylate (PMMA)
Polymethyl methacrylate is also called acrylic. Moreover, you can notice the good optical properties, high gloss, and scratch-resistance of polymethyl methacrylate from this plastic.
6. Polypropylene (PP)
Generally polypropylene cheap resin material gives high impact resistance in certain grades. But the interesting thing is that it is brittle at cold temperatures (in the case of propylene homopolymers).
7. Polybutylene terephthalate (PBT)
Only the good electrical properties make polybutylene terephthalate ideal for power components. Not only that, but it also helps to make it ideal for automotive applications. Similarly, depending on the filling of the glass, the range of energy is from medium to high. In addition, it is interesting that incomplete grades are hard and flexible.
8. polyphenyl sulfone (PPSU)
Polyphenylsulfone holo is a dimensionally stable component of high strength, temperature, and heat resistance. And they also make PPSU radiation alkali disinfectants and are resistant to weak acids.
9. Polyether Ether Ketone (PEEK)
Polyether ether ketone provides high-performance or high-temperature resin heat resistance and flame retardancy, excellent strength, and dimensional stability resistance.
10. Polytheramide (PEI)
Polyetherimide has excellent strength and dimensional stability. Interestingly, it usually helps to provide high-temperature resistance and flame retardation along with chemical resistance.
