The Basics: Polymer Definition and Properties
Here you’ll learn the definition and properties of polymers, another name for plastics. The simplest definition of a polymer is a useful chemical made of many repeating units. A polymer can be a three dimensional network (think of the repeating
Polymers are all created by the process of polymerization wherein their constituent elements called monomers, are reacted together to form polymer chains, i.e 3-dimensional networks forming the polymer bonds. The type of polymerization mechanism

4. Polypropylene (PP) This plastic material is a thermoplastic polymer and the world’s second-most widely produced synthetic plastic. Its widespread use and popularity are undoubted because polypropylene is one of the most flexible
These are among the most effective antiperspirants, but can cause skin irritation if instructions aren’t followed precisely. Typically, aluminum chloride hexahydrate concentrations of 10% to 15% are recommended for excessive sweating of the
Basic chemicals
Basic chemicals, produced in large quantities, are mainly sold within the chemical industry and to other industries before becoming products for the general consumer. In this group of units, each chemical is described in the same way, in three
A few things: Types 1 and 2 plastics may be tossed into standard recycling bins. Other plastic types may not be permitted in your bin, depending on your municipality’s guidelines. Hard-to-recycle plastics – including Styrofoam, shrink wrap and
Specifying Engineer- Selecting pipe and piping materials
Just as the properties of different pipe materials vary widely (see Table 1), the importance of these properties varies widely between projects. The piping material chosen depends on the application and the water quality. For example, heating
Here’s a detailed list of the different types of plumbing pipes and tubing used in residential house plumbing systems. We include an explanation for what each type is used for along with a photo example of each. At the end check out a pipe size
What is Polymerization? - Definition, Types & Examples - Video & Lesson Transcript | Study
Draw a structure of a polymer formed from 3 molecules of sebacoyl chloride and 3 molecules of ethylene glycol. Vinylidene chloride, CH_2 = CC1_2, is copolymerized with vinyl chloride to make Saran

How to Recognize Different Types of Pipes - dummies
There are two common types of copper pipe: Rigid copper, which comes in three thicknesses. Type M is the thinnest but is strong enough for most homes. Types L and Type K are thicker and used in outdoor and drain applications. To cut rigid
Basic Forms of PVC Polyvinyl Chloride is widely available in two broad categories: Flexible and Rigid. But, there are more types like CPVC, PVC-O and PVC-M. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm 3): Flexible PVC is formed by the
- What methods are used to treat electroplating industry wastewater?
- This article examines and assesses new approaches such as coagulation and flocculation, chemical precipitation, ion exchange, membrane filtration, adsorption, electrochemical treatment, and advanced oxidation process (AOP) for treating the electroplating industry wastewater.
- Can electro-coagulation remove heavy metals from electroplating wastewater?
- The application of the electro-coagulation process proved to be an efficient treatment technology for the removal of metals from electroplating wastewater. Combination of lime and ferric chloride was more efficient for the precipitation of heavy metals from industrial electroplating wastewater than other chemical coagulants.
- What is electroplating industry wastewater?
- Electroplating industry wastewater involves highly toxic cyanide (CN), heavy metal ions, oils and greases, organic solvents, and the complicated composition of effluents and may also contain biological oxygen demand (BOD), chemical oxygen demand (COD), SS, DS, TS, and turbidity.
- Where is industrial electroplating wastewater collected?
- Industrial electroplating wastewater effluent was collected from Candilars metal electroplating plant, Cairo. This plant consumes about 100 m 3 of water daily in the electroplating process, 80% of wastewater is reused after treatment for rinsing the electroplated pieces.
