Styrene - US EPA
Styrene is used predominately in the production of polystyrene plastics and resins. Styrene is also used as an intermediate in the synthesis of materials used for ion exchange resins and to produce copolymers. (1) Sources and Potential Exposure Indoor air is the principal route of styre 3 ne exposure for the general population.
Catalytic Techniques for Upcycling Plastic Waste - ACS Axial
Given the urgent need to improve upon existing plastic recycling methods, more researchers are turning toward chemical routes for plastic reclamation. 1 Closed-loop chemical recycling depolymerizes plastics into their constituent monomers or oligomers, which can be used to resynthesize the same plastics with virgin-like material properties.
Promoting plastic recycling - potential for PS and ABS. - Sesotec
Polystyrene, or PS for short, is one of the standard plastics and is used - either as a thermoplastic material or as foam (EPS) - in many areas of everyday life. Above all, disposable articles made of polystyrene have become established in the scientific field as well as in many economic and household sectors.

- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- How do polystyrene microplastics Leach phthalate acid ester plasticisers?
- Diphenol and phthalate acid ester plasticiser leaching from polystyrene microplastics displayed different leaching dynamics. Polymeric free volume and the hydrophobicity of the plasticiser influenced leaching. Water agitation and temperature enhanced leaching. Smaller microplastics leached more plasticiser.
- Which plasticisers are used in the plastics industry?
- It is estimated that phthalate acid ester (PAE) (such as diethylhexyl phthalate; DEHP and dioctyl terephthalate; DEHT) and diphenol (such as bisphenol A; BPA and bisphenol S; BPS) plasticisers contribute to over 80 % of all plasticisers used in the plastics industry (Marturano et al., 2019; Tiseo, 2021).
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
