Phenolics are a type of thermosetting polymers that has specific properties. Because of these specific properties, phenolics are used in various application areas. In here, we explained these application areas of phenolics and some of properties about phenolics. Also you can find numeric informations about phenol formaldehyde thermoset.
What Are The Phenolics?
The source chemical of phenolics is phenol. Phenols have chemical structures of C6H5OH and can be reactec with aldehydes which are the dehyrogenated alcohols. From these alcoholos, formaldehydes are the most reactive one. Because of thati phenol formaldehyde is the most important phenolic thermosets.
Phenolics have brittle structure which is also general characteristic of thermoset materials. They have very good thermal and chemical stability. Some of applications that phenolics and phenol formaldehyde are;
- Phenol formaldehydes can be used on brakes and abrasive wheels as bonding material.
- Printed circuit boards are also very important application area for phenol formaldehydes.
- they are also used as adhesives for plywood.
In the production process of phenol formaldehyde, some of fillers must be used. The general fillers are used for phenolics some of minerals, wood flour and cellulose fibers.
General Properties Of Phenol Formaldehyde
Constituent chemicals for phenol formaldehyde are phenol and formaldehyde. These two has chemical formulae of C6H5OH and CH2O respectively. Because of their brittle behaviour, they have very low elongation value according to their original shape which is >1%. Tensile strength of phenol formaldehydes is around 70 MPa and modulus of elasticity is around 7000 MPa. The production method of phenol formaldehyde is step polymerization process.
These are the general characteristics of phenolics and phenol formaldehyde. Do not forget to leave your comments and questions about phenolics and phenol formaldehyde below. Your precious feedbacks are very important for us.
