Polystyrene (PS), abbreviated as PS, refers to a polymer synthesized by free radical addition reaction of styrene monomer, with the chemical formula (C8H8) n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.

The English name for polystyrene is Polystyrene, abbreviated as PS. PS is a thermoplastic non crystalline resin that is polymerized from styrene monomers and can be synthesized through various synthetic methods. In industry, bulk polymerization and suspension polymerization are mainly used. PS is mainly divided into general grade polystyrene (GPPS, commonly known as transparent benzene), impact grade polystyrene (HIPS, commonly known as modified benzene), and foam grade polystyrene (EPS).
General grade polystyrene is a thermoplastic resin that is colorless, odorless, odorless, and glossy, transparent, bead like or granular solid.General grade polystyrene is a thermoplastic resin that is colorless, odorless, odorless, and glossy, transparent, bead like or granular solid. It is soluble in Aromatic hydrocarbon, chlorinated hydrocarbons, aliphatic ketones and esters, but can only swell in acetone. It can withstand the action of certain mineral oils, organic acids, alkalis, salts, lower alcohols, and their aqueous solutions. Low water absorption, able to maintain its mechanical properties and dimensional stability in humid environments. The optical performance is second only to acrylic resin. Excellent electrical performance, high volume and surface resistivity, and unaffected by temperature and humidity changes, as well as corona discharge. The radiation resistance is also very good. Its main drawbacks are brittle and easy to crack, low impact strength, poor heat resistance, and inability to withstand boiling water. It can only be used at lower temperatures and loads. Poor sunlight resistance and flammability. When burning, it emits black smoke and has a special odor.
The 68# industrial white oil produced by WJWAX is very suitable for the production and processing of PS(Polystyrene), and customer feedback has been very good. If you need to purchase similar white oil products, you can contact our factory for a quotation, with first-hand supply and excellent quality.
Here are a few key points about using white mineral oil as a plasticizer for polystyrene (PS):
White mineral oil is a paraffinic mineral oil that is commonly used as a plasticizer for polystyrene. It helps make the polystyrene more flexible and workable.
The white mineral oil needs to meet specifications for use in PS. A common grade is White Mineral Oil NO.68, which has a viscosity of about 68 cSt at 40�°C.
Product Application
The mineral oil is typically added at 10-15% by weight to the polystyrene resin before processing. Too much oil can make the PS too soft while too little may not provide enough plasticization.
The mineral oil does not chemically react with the PS. It works by embedding between the polymer chains, spacing them apart. This increases chain mobility and flexibility.
After processing, the mineral oil may slowly migrate out of the PS over time, resulting in embrittlement. This may limit use of mineral oil for long-term flexible PS products.
Proper mixing and temperature control is needed when adding the mineral oil to ensure uniform plasticization without degrading the PS.

FAQs
What are the typical usage levels of white mineral oil when plasticizing polystyrene?
White mineral oil is typically used at 10-15% by weight relative to the polystyrene resin. Lower levels may not provide enough plasticization while higher levels can make the polystyrene too soft.
Does the mineral oil react chemically with the polystyrene?
No, the mineral oil does not chemically bond to the polystyrene. It works by embedding between the polymer chains and spacing them apart. This increases mobility and flexibility but means the oil can migrate out over time.
What grade of mineral oil is commonly used as a plasticizer for polystyrene?
White Mineral Oil NO.68 is a common choice. It has a viscosity of about 68 cSt at 40C. The grade needs to be selected to provide the desired level of plasticization at typical processing temperatures.
Polystyrene (PS) plastic is a naturally transparent thermoplastic that is available as both a typical solid plastic as well in the
form of a rigid foam material. PS plastic is commonly used in a variety of consumer product applications and is also particularly
useful for commercial packaging.
Polystyrene (PS) for Prototype Development on CNC Machines and 3D Printers: Polystyrene is available in sheet stock, rod stock,
and in various shapes. It is a great candidate for subtractive machining processes on a CNC machine. Colors are usually limited to
clear, white, and black although colors can be added and it is an excellent candidate for external painting.
Polystyrene (PS) for� Injection Molding:
General Purpose Polystyrene (GPPS) and High Impact Polystyrene (HIPS) are probably the most commonly used PS resins for injection
molding. GPPS is clear, but brittle (think of a CD jewel case) while HIPS is opaque and much less brittle.
