Properties and Applications of Thermoset Plastics

1.Phenol-Formaldehyde (PF)

Polics are thermosetting resins which are typically stiff and brittle. Phenolic resins were first tigated in the 1880s by Otto Bayer. In 1909, Dr. Bakeland produced the first commercial phenolic ing compound. But it was Harry H Dent founder general Plastics, who in 1921 developed the first nuous process for making phenolic moulding pounds. Phenolic resins are manufactured by plining phenol and formaldehyde. Two types of polic resin namely resols and novolaks are manuactured. Resol refers to a phenolic resin made acting 1.2 to 1.5 moles of formaldehyde with one of phenol in basic medium. Novolak is the resin the by reacting 0.8 mole of formaldehyde with one of phenol in acidic medium. The approximate tures of resols and novolaks are shown below:


  • Hard, stiff & brittle

2. Amino Plastics

Urea-formaldehyde (UF) and Melamine-formaldehyde (MF) are called as amino plastics. These resins are derived from ammonia and hence they are referred as amino plastics. Urea formaldehyde was first produced in 1920s by Kurt Ripper & Firtz Pollac in Germany. Urea formaldehyde was commercialised in the year 1932 in America by the American Cyanamid Co. Melamine formaldehyde was commercialised in 1939 at American Cyanamid Co. When Urea or melamine is reacted with formaldehyde a clear thermosetting resin of urea formaldehyde or melamine formal dehyde is produced.

3. Epoxy Resins

Chemically, the term "epoxy" means a three membered ring containing one oxygen and two carbon atoms.

The molecules of 'epoxy resins are low in molecular weight and when cured they are joined together to form large cross linked structures. These final products are thermosets. Epoxy resins were first developed in 1930s in Germany. But the material was commercialised in 1946. Epoxy resins are manufactured by reacting polyhydric alcohols with epichlorohydrin. The largest produced epoxy resin called Diglycidyl Ether of Bisphenol-A (DGEBA) is produced by reacting bisphenol-A with epichlorohydrin.

Epoxy resins are cured with different curing agents like amines, amides, acids, acid anhydrides and amine aducts. Also, they are catalytically cured using tertiary amines. By selecting a suitable resin and a curing agent we can get a range of properties for different applications.

4. Unsaturated Polyester Resins

Unsaturated polyesters are very versatile materials. They can be rigid, resilent, flexible, corrosion resistant and weather resistant. These resins were first synthesised in the year 1936 by Carleton Ellis and commercialised in 1941.

Unsaturated polyesters are usually manufactured by batch process. They are the condensation products of unsaturated dibasic acids (usually maleic anhydride), saturated dibasic acids and glycols. The glycols used may be ethylene glycol, propylene glycol or diethylene glycol. Important saturated acids used are phthalic anhydride and m-phthalic acid. The most common cross linking monomer used is styrene but vinyl toluene, methyl methacrylate and diallyl phthalate can also be used. Structure of Isophthalic acid polyester resin is given below:

5. Polyurethane

Polyurethanes are a wide variety of polymers with quite different compositions and correspondingly different properties. The characteristic structural element of almost all of these polymers is the urethane group formed in the course of polyaddition. In 1937, Otto Bayer and co-workers discovered the diisocynates addition polymerization that resulted in the preparation of many different types of polyurethanes. Although such polymers can be formed by a number of different chemistries, the most common method is by the reaction of a polyisocyanate with an organic polyhydroxy material (Polyol).

Polyurethanes are the most important class of polymers playing a vital role in many industries from ship building to footwear; construction of cars. They appear in an astonishing variety of forms. The various types of unsaturated polyurethanes are foams (Low density flexible foams, low density rigid foams, high density rigid foams), solid polyurethanes, adhesive, binders, coatings and paints. Plastics as such are harmless and environmental friendly. Among the various waste management options, plastics recycling is more ecofriendly and energy saving. Mechanical recycling is widely adopted in India ever since the manufacturing of plastic raw materials. Due to economic reasons recycled plastic materials find various applications from small gem clips to large pallets.

In general, polyurethanes are addition polymers manufactured by the reaction of di-or poly-isocyanates with polyols.

The reaction is exothermic. The rate of the polymeriation reaction depends upon isocyanate and the polyol.


In addition to isocyanates and polyols a wide range of chemicals may be added to control and modify both the polyurethane reaction and the properties of the final polymer. They include:

  • Catalyst
  • Chain extenders
  • Crosslinking agents
  • Surface active materials
  • Flame retardants
  • Colourants and
  • Fillers


Polyurethanes have found wide application in virtually every industry because of their characteristic general properties, the most important of which are :

  • High elasticity over the entire hardness range
  • Flexibility over a wide temperature range
  • Good weather resistance
  • Good resistance to oil, grease and many solvents

6. Silicones

Silicones may be defined as synthetic compounds containing alternating silicon-oxygen backbone. This inorganic backbone is chemically modified with pendant organic groups to add flexibility and reactivity. Modern developments in silicone chemistry have sprung from Kipping's researches.

Silicon is manufactured by the reduction of silicon dioxide in electric furnaces. The elemental silicon is reacted with gaseous methyl chloride in the presence of copper catalyst to provide methyl chlorosilanes which are fractionated and the resultant dichlorodimethyl silane is hydrolysed with water to form linear and cyclic poly siloxanes.

Polyorganosiloxanes are normally referred to as 'silicones' and are polymeric substances with the structure given above. A wide variety of silicone resins are available commercially. The properties of the individual types differ somewhat depending upon the use for which they are designed. Silicones form the basis of a wide range of industrial products which may commercially be classified as fluids, resins and elastomers or rubbers.

Silicone forms

Silicone Fluids

A large number of silicone fluids have been synthesised and studied. Dimethyl silicone fluids and other silicone fluids belong to this category.

Silicone Resins

They are highly branched polymers that cure to solids


Silicone Elastomers

These are based on linear polymers of very high molecular weight which are analogous to the silicone fluids. Mechanical strength is imparted by the addition of suitable inorganic fillers and elastic properties are obtained as a result of intermolecular cross linking in the presence of an oxidising curing agent.

Silicone elastomers are manufactured in several forms: heat-cured rubber, liquid injection moulding elastomers, one-component room temperature vulcanizing sealants (RTV), two component RTV products and speciality fluorosilicones.


Silicone fluids

  • Transparent to visible light and UV radiation
  • Low pour point
  • High temperature stability
  • High compressibility
  • General inertness
  • Relatively constant viscosity over temperature
  • Unstable towards concentrated mineral acids

Silicone Resins

  • They resemble glass but are somewhat softer and usually soluble in solvent until cured.
  • Degree of hardness depends on the extent of cross linking
  • Very good heat resistance
  • Highly water-repellant
  • The resins are good electrical insulators particularly at elevated temperatures and under, damp conditions.
  • Have good resistance to most aqueous chemical reagents
  • Good inherent weatherability
  • Resistance to many organic solvents is poor

Silicone fluids

They are used in vinyl polishes and high temperature greases. Their most important application in relation to the plastics industry is as mould release agents. They are used as additives in polishes and waxes, heat-transfer fluids, electrical transformer fluids, textile fibre lubricants, antifoaming agents in chemical processes & carriers and softness in cosmetics.

(b) Silicone Resins

Silicone resins are employed in a wide and increasing range of industrial applications. These include surface coatings, high temperature paint additives, electrical moulding compounds, masonry water repellants, abrasion resistant coatings for plastics, tackifiers for silicon adhesives and for electrical applications.

Abrasion resistant silicone coatings are used to protect transparent plastics against scratches, chemical attack and UV degradation. Silicone is widely used as the release coating on plastic film label stock.

The use of silicone resins in paints and other surface coatings depend on their heat resistance, water repellency and resistance to chemical reagents. A blend of silicone and organic resins pigmented with aluminium powder is used in applications such as coatings for metal chimneys, exhaust pipes and furnace doors involving exposure to temperatures upto 500°C.

Silicone resins form useful release agents and although more expensive initially are more durable. To release confectioneries from baking pans, these resins are used.

Silicone laminates are used in electrical applications such as slot wedges in electric motors, terminal boards, printed circuit boards and transformers.

Silicone Elastomers
