What are the properties of high impact polystyrene?
High Impact Polystyrene (HIS) sheet is a tough, low cost, easy to thermoform, fabricate, and machine plastic material. It has high impact strength and is easy to glue, paint, and print. Typical uses for HIS are POP displays, indoor signs, and check sockets for orthotics and prosthetics.
Is high impact polystyrene heat resistant?
They are used in many applications have been able to compete with expensive engineering resins in the field. The outstanding characteristics of impact-resistant polystyrene are easy processing, excellent dimensional stability, high impact strength and high rigidity. HIPS is only in heat resistance.
What are the properties of polystyrene?
Polystyrene Characteristics Unmodified polystyrene is clear, rigid, brittle and moderately strong. Its electrical properties as a dielectric material are good, though it has relatively low heat resistance. Polystyrene is soluble in most chlorinated and aromatic solvents, though not in alcohols.
What is the melting point of high impact polystyrene?

What is the difference between polystyrene and high impact polystyrene?
High impact polystyrene is a low cost, tough plastic material that easily undergoes thermoforming and fabrication. The key difference between polystyrene and high impact polystyrene is that polystyrene generally has comparatively low impact strength, whereas high impact polystyrene has very high impact strength.
Is high impact polystyrene flexible?
High Impact Polystyrene, otherwise known as HIPS, is a flexible material that can be molded, cut, bent, vacuumed, easily printed on, and fabricated. HIPS has a very low heat deflection temperature, a very low chemical resistance, it does not absorb moisture, and it is relatively stable dimensionally.
Is high impact polystyrene waterproof?
High-Impact Polystyrene, more commonly known simply as styrene or HIPS, is a low-cost, very rigid, and easy to work with plastic for a wide range of applications where customers need something that is stiff, durable, and water resistant.
What is high impact polystyrene made of?
High impact styrene sheet, often known as HIPs, is a type of material that is made from plastic polymers. Like all thermoplastics, the plastic polymers in the bonds allow the material to melt, cool and solidify when exposed to certain temperatures.
What is the glass transition temperature of polystyrene?
about 100 °C.
Introduction. The glass transition temperature (Tg) of syndiotactic polystyrene (sPS) is about 100 °C.
What temperature does styrofoam Leach?
Styrofoam has a maximum safe temperature of 175 degrees Fahrenheit, and it will start to warp at around 22 degrees Fahrenheit, which is boiling point.
What is the melting point of styrofoam?
410-480 °F
What are the properties of PS?

What is meant by high impact polystyrene?
HIPS (High Impact Polystyrene), also known as PS (Polystyrene), is an amorphous thermoplastic material, used in lower heat applications. It is categorized as a standard material, and offers ease of processing, high impact strength, and stiffness.
Why choose high impact polystyrene (his)?
We’re here to help. High Impact Polystyrene (HIS) sheet is a tough, low cost, easy to thermoform, fabricate, and machine plastic material. It has high impact strength and is easy to glue, paint, and print. Typical uses for HIS are POP displays, indoor signs, and check sockets for orthotics and prosthetics.
What is the flammability of polystyrene?
In expanded polystyrene, these are usually hydrocarbons such as pentane, which may pose a flammability hazard in manufacturing or storage of newly manufactured material, but have relatively mild environmental impact.
What are the characteristics of polystyrene?
Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year.
What is the strength of extruded polystyrene?
Extruded polystyrene is about as strong as an unalloyed aluminium but much more flexible and much less dense (1.05 g/cm 3 for polystyrene vs. 2.70 g/cm 3 for aluminium). Polystyrene is an addition polymer that results when styrene monomers interconnect ( polymerization ).
