Styrene is the monomer of the polystyrene, which is a well-known thermoplastic polymer. Elastic (Young's, Tensile) Modulus, GPa: 1.9: 1.9 to 2.9: Elongation at Break, % 40: High-impact polystyrene is a polystyrene resin that’s used in lower heat applications. on average for XPS vs. 0.93 lbs. HIPS is naturally a white color and has a matte finish, and while it’s not naturally transparent, HIPS can be painted on and glued easily for excellent aesthetics. Polystyrene foam presents unique management issues because of its lightweight nature, floatability, and likelihood to be blown from disposal sites even when disposed of properly. While there are some key differences between high-impact and general-purpose polystyrene resins, they do share several characteristics. Several HIPS grades are designed to have exceptional resistances for specific end-use, such as in refrigeration liners, toilet seats and tanks, or disposables that require high environmental stress crack resistance. Main Difference – Styrene vs Polystyrene. PS is widely used to produce high impact styrene sheets which are further used for producing models, prototypes, signs, displays, enclosures and more. GPPS is clear, but brittle (think of a CD jewel case) while HIPS is opaque and much less brittle. This makes HIPS something we call and immiscible blend of polystyrene and polybutadiene. HIPS (High Impact Polystyrene ) HIPS stands for high impact polystyrene. Not all the chains in HIPS are branched like this. for EPS). Polystyrene Chemical Resistance Chart, Inorganic Acids, Organic Acids, Alkalies, Alcohols, Ketones, Esters, Ethers, Hydrocarbons, Miscellaneous Success! Mechanical Properties. These methods of processing include injection molding, extrusion, blow molding and thermoforming. Monomers bind with each other via covalent bonds to form a polymer. High Impact Polystyrene (HIPS) and Rigid Vinyl (sometimes referred to as PVC or RPVC) are often the main films considered for a variety of lower cost applications such as point-of-purchase signage, shelf danglers, membership and loyalty cards, and tags to name a few.

Where a blowing (or expanding) agent is added to the polystyrene, the product is referred to as an expandable polystyrene. High impact polystyrene (HIPS) provides impact resistant solutions for a variety of applications, including printed graphics, refrigerator interiors, and bathware. HIPS is a modified material of PS, divided rubber composition containing 5-15%, the toughness of PS increased about four times the impact strength is greatly increased. Easy to fabricate, this resilient material costs little to produce and offers applications in many industries. General Purpose Polystyrene, also known as crystal-clear polystyrene, is fully transparent and rigid, and is widely used in food packaging applications or jewel cases. General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS) are probably the most commonly used PS resins for injection molding. High Impact Polystyrene sheet is available in the following sizes, with custom sizes available by custom order. Back in the day, the most common application of GPPS was seen in the cases that enclosed CDs. PS, High Impact (HIPS) Static. High Impact Polystyrene, on the other hand, is impact resistant at the cost of not being naturally clear or transparent. The lightweight and buoyant polystyrene travels easily through gutters and storm drains, eventually reaching the ocean. How Is General Purpose Polystyrene (GPPS) Different from High Impact Polystyrene (HIPS)? Click here to request free samples of our clear polystyrene plastic boxes.

Polyethylene is remarkably dense and available in sheets, film, and fibrous forms. Polystyrene foodservice packaging typically insulates better, keeps food fresher longer and costs less than alternatives. While they share many core characteristics, there are distinct pros and cons to each. Each has unique properties that should be taken into account before deciding which one is best for your project and end-user. 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). Early production processes for HIPS were based on mixing PS moulding materials with a rubber component. The key difference between polystyrene and polypropylene is that the monomer for polystyrene is styrene, while the monomer for polypropylene is propylene.. Polymers are large molecules, which have the same structural unit repeating over and over. Polystyrene is used for the housing and other parts for televisions, computers and all types of IT equipment, where the combination of form, function and aesthetics are essential.

Both ABS and HIPS are thermoplastics. GPPS is brittle and has low-impact strength as well as less dimensional stability than HIPS. Inquiring about the different types of plastics is as good as asking how many varieties of cheese are out there. The key difference between styrene and polystyrene is that it is the polymerization of styrene that forms polystyrene, a synthetic thermoplastic elastomer. It is commonly understood that XPS offers more initial R-value per inch than EPS but because of its lower cost, EPS offers more R-value per dollar. It is worth noting that both polypropylene and polystyrene tubes are commonly used in scientific and medical research, and meet both domestic and international regulation.
