What Is High Impact Polystyrene?
High Impact Polystyrene (HIPS) is a thermoplastic polymer made from a combination of polystyrene and rubber (elastomer). The addition of the elastomer gives HIPS its unique properties including improved impact resistance and toughness, making it suitable for a wide range of applications.
As it is a thermoplastic polymer, it means that it softens when heated and hardens when cooled. HIPS has a relatively low melting point, making it easy to process using injection molding, extrusion, and thermoforming techniques. It also has good dimensional stability, meaning it retains its shape and size even when subjected to changes in temperature and humidity.
When Should You Use High Impact Polystyrene?
High Impact Polystyrene (HIPS) can be used in a variety of applications where its unique properties are beneficial. Some examples of when HIPS may be a suitable material choice include:
Packaging: HIPS is commonly used in the manufacture of packaging materials, such as clamshells, trays, and containers. Its high impact resistance and customizable properties make it an ideal choice for protecting fragile items during shipping and handling.
Toys: HIPS is often used in the manufacture of toys due to its durability, impact resistance, and lightweight properties.
Automotive parts: HIPS is commonly used in the manufacture of automotive parts, such as instrument panels, interior trim, and exterior body parts. Its high impact resistance and dimensional stability make it suitable for use in applications where strength and durability are important.
Electronic components: HIPS is used in the manufacture of electronic components and housings due to its good electrical insulation properties.
Signage: HIPS can be easily customized in terms of color, texture, and finish, making it a popular choice for signage applications.
What Are The Benefits Of High Impact Polystyrene?
HIPS is a very popular material, especially within the manufacturing industry. Take a look at just some of the reasons why:
Impact Resistance
HIPS has excellent impact resistance, meaning it can withstand heavy loads and impact without cracking or breaking.
Cost
It is relatively low-cost compared to other thermoplastic materials with similar properties, making it a great choice for cost-sensitive applications.
Processing Ease
HIPS can be easily processed using techniques such as injection molding, extrusion, and thermoforming.
Dimensional Stability
HIPS maintains its shape and size even when subjected to changes in temperature and humidity.
Weight
HIPS is a lightweight material, which makes it suitable for applications where weight is a concern.
Electrical Insulation
HIPS has good electrical insulation properties, making it suitable for use in electronic components and housings.
What Are The Negatives Of High Impact Polystyrene?
While High Impact Polystyrene (HIPS) has several positive qualities, there are also some negative qualities to consider:
Limited temperature resistance: HIPS has a relatively low melting point and may not be suitable for applications where high temperatures are involved.
Limited chemical resistance: HIPS may be susceptible to damage from certain chemicals, such as solvents and acids, which can cause it to become brittle or degrade.
Flammability: HIPS is a flammable material and may not be suitable for applications where fire resistance is required.
Not suitable for outdoor applications: HIPS may not be suitable for outdoor applications as it can degrade when exposed to UV radiation and weathering.
Poor barrier properties: HIPS has poor barrier properties, meaning it may not be suitable for applications where moisture or other environmental factors need to be kept out.
Environmental concerns: HIPS is a non-biodegradable material and can contribute to environmental issues if not properly disposed of or recycled.
