The term is usually brought up when we discuss benzene derivatives. These derivatives were called aromatic because of their pleasantly sweet smell. Aromatics compounds have a configuration of six carbon atoms, which is called the benzene ring. However, there are compounds that are non-benzene but still aromatic.
Based on their network structure, Polymers are divided into four groups
These contain polymer chains that are long, linear, and one-dimensional and are kept together by weak forces such as intermolecular interactions. They become formable and free-flowing when they are exposed to a certain amount of heat, but when they are cooled down, their rigid behavior returns. This process can be repeated as many times as required, as it is purely physical.
Duromers are tightly cross-linked polymers that have the behavior of not melting under raised temperatures and can retain their network structure. At room temperature, they remain hard and brittle.
Example: Epoxy resin
Elastomers, as the name suggests, are incredibly elastic and are also cross-linked chemically. Vulcanization doesn’t make them formable. The temporal deformity is expressed by these materials when specific external forces are applied. Upon removal of the forces, however, they retain their original structure. They are also called rubbers.
These elastomers are different since they contain thermoplastic end blocks along with an elastic midblock making the material free-flowing and formable. When cooling happens, physical cross-links take place which forces flexible blocks into rigid three-dimensional networks. This makes thermoplastic have the properties of elastomers, but the behavior it shows enables it to be processed just like thermoplastics.
Our supply of polymers include:
- Polyethylene (PE)

- Polypropylene (PP)
- Acrylonitrile butadiene styrene (ABS)
- Polyvinyl chloride (PVC)
- Polyethylene terephthalate (PET)
Fertilizer is a material that could be natural or made synthetically that is applied to plant tissues such as leaves and soils so that the fertilizer can supply plants with the nutrients it needs to grow.
Fertilizers are an essential component when it comes to soil fertility as they are the reason that we see them, over the past few decades, an increase in crop yields in European countries.
Olefin, which is also known as an alkene, is a compound that consists of hydrogen and carbons where one or more carbons are held together by a double bond. Olefins are unsaturated hydrocarbons, compounds that have at least a double or a triple bond and consist of only hydrogen and carbon.
They are divided further into two groups called cyclic or acyclic (aliphatic) olefins. These have double bonds that are placed between carbon atoms forming part of a cyclic (closed-ring) or of an open-chain grouping, respectively, just like monolefins, diolefins, triolefins, etc. In all of them, the number of doubles bonds per molecule is, respectively, one, two, three, along with other numbers.
