The polyester resin is then said to be ‘cured’. It is now a chemically resistant and usually hard solid. The cross-linking or curing process is called ‘ isation’. It is a non-reversible chemical reaction. The ‘side-by-side’ nature of this cross-linking of the molecular chains tends to means that polyester laminates suffer from brittleness when shock loadings are applied.【Get Price】

Density measures the mass per unit volume.It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity loss of plasticizers absorption of solvent etc. It is important to note that density varies with temperature.
