Impact strength is measured in high impact polystyrene with different layers. In general, butadiene is used to make HIPS polystyrene. This increases the strength of the polystyrene; Because butadiene is a substance that is very resistant to impact and pressure.

It should be noted that HIPS polystyrene is used in various industries. This material is very flexible and resistant to impact and moisture. There are several methods for measuring impact strength in HIPS. In this PETROPROVIDERS article, join us to show you impact strength tests.

HIPS polystyrene and its applications

Introduction of impact strength

Introduction of impact strength

This polystyrene is a kind of impact-resistant grade that is used in various industries. To produce this polystyrene, styrene monomers are combined to form a strong structure. The structural composition of styrene consists of 8 carbon atoms and 8 hydrogen atoms and is represented as (C8H8)n.

It is impact-resistant and is used for various applications. This material is also resistant to temperature and is used for insulation of buildings and construction. HIPS polystyrene is used in the production of various plastic materials such as toys, car parts, home appliances, and electrical insulation.

Introduction of impact strength measurement tests in HIPS

One of the most important tests to measure impact strength in HIPS is the impact test. This test is very simple and has standards; These standards must be met to determine the conditions for testing. In this test, there is a device with different parts that determines the impact resistance of polystyrene.

This device has a pendulum that hits the polystyrene. In this test, one of the important parameters is the energy absorbed by the HIPS sample. In general, this pendulum hits the HIPS sample and its energy is recorded. This energy should indicate the impact resistance of the polystyrene.

In this experiment, the pendulum is removed from the sample and then released. This then strikes the sample and the height of the pendulum and its impact speed are calculated. This indicates the value of impact strength. In this test, if the pendulum energy is higher, the polystyrene material is more impact resistant. But if the energy is low, it means that the material has little impact resistance and breaks easily.

In this test, the angle of impact of the pendulum on the HIPS sample is investigated and the strength of the material is calculated in the form of energy. In this test, if the material has low strength, it is called plastic, and if it has high strength, it is called some kind of elastic.

The higher the energy, the greater the resistance of the material to the impact of the pendulum. Therefore, this test shows how strong the polystyrene material is and whether its material is soft or hard.

The most common methods for measuring resistance in polystyrenes

There are two very common methods around the world. These two methods are the Charpy method and the Izod method. In the Izod method, the HIPS specimen is placed vertically and the notch recorded on the pendulum is hit. But in the Charpy method, the test specimen is placed horizontally and the notch is far from the pendulum.

Another difference between the two methods is that in the Izod method, there is only one type of gap, but in the Charpy method, there are two types of collision gaps. These two tests are used for plastic and composite materials. It should be noted that the Izod method is used to measure impact strength in HIPS. In the following, we will fully explain this method.

Introduction of Izod test to measure impact strength in HIPS

This method is one of the best methods for measuring impact resistance. This method is very simple and its principles are by ISO 180 and ASTM D256 standards. It does not require much equipment to perform this test.

In this system, the pendulum support is measured and recorded according to the sample. This sample can be produced by extrusion, injection molding, and compression molding. The HIPS specimen in this method should be 64 mm long, 12.7 mm wide, and 3 to 12.7 mm thick.

In addition, the sample slit should be of the V type. The HIPS sample should have parallel surfaces and be produced perfectly smooth. This material should not have sharp surfaces or edges or scratches. If a sample does not meet all of these conditions, it cannot enter the impact strength test. To perform the Izod test on HIPS polystyrene, 10 samples must be entered into the device.

In this bribe, the HIPS material enters the system vertically and is held by the bases. Then, the pendulum rises to a certain height and is fixed there. In the next step, this pendulum is released to hit the desired point.

In this test, the height of the pendulum, the type of polystyrene, the type of impact, and the intensity of the impact are determined. After the pendulum collides with the HIPS sample, the absorbed energy is measured. Then, this energy is recorded by the device and its diagram is drawn.
