Major industrial polymers | Types, Examples, & Facts
In plastic (thermoplastic and thermosetting resins), polymers are divided between those that are soluble in selective solvents and can be reversibly softened by heat (thermoplastics) and those that form three-dimensional networks which are not soluble and cannot be softened by heat without decomposition (thermosets).
Polymers and Plastic Resins Selection Guide
Polymers and plastic resins are compounds comprised of two or more repeating organic or synthetic base molecules. They are widely used as raw materials in plastics molding and fabrication operations. Polymerization Synthetic polymer chains are formed by reacting two or more organic monomer molecules together.
Specialty Polymers & Compounds | Dow Inc.
Polymers are large molecules consisting of a repeating series of linked smaller molecules, called monomers. Synthetic polymers are generally made from petroleum, and yield a range of plastic materials such as polyethylene, rubber and nylon. Polymers derived from two or more different monomers are known as copolymers.
Polymer | Description, Examples, Types, Material, Uses
Polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids. Moreover, they constitute the basis of such minerals as diamond, quartz, and feldspar and such man-made materials as concrete, glass, paper, plastics, and rubbers.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- 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.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- 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:
- Why are plasticizers used in electrical insulating materials?
- In specific applications, plasticizers can influence the dielectric properties of polymers. This makes them suitable for use in electrical insulating materials. Plasticizers can enhance compatibility between polymers and various additives or fillers. This results in more homogeneous and stable formulations.
- What is the Ultimate Guide to plasticizers in 2024?
- Welcome to the Ultimate Guide to Plasticizers in 2024. This comprehensive resource provides an in-depth exploration of plasticizers, crucial additives that enhance the flexibility and processability of polymers. The guide will outline their classifications, delve into their applications, and compare different types.
