FREE Report Published: Nanoindentation - An Evaluation of the Effect of Ultraviolet Light on the Surface Properties of Recycled Polypropylene

The Polymer Sector of the Materials Knowledge Transfer Network has produced a report dealing with "nanoindentation - an evaluation of the effect of ultraviolet light on the surface properties of recycled polypropylene". The potential for the use of recycled polypropylene can be heavily influenced by the effect of UV on the surface of the moulded component.

Attempts to quantify the effect have been difficult, since when the UV exposed component is re-ground and re-moulded the surface layer is incorporated into the bulk material.

The possible effect is therefore lost when subsequently the recycled product is tested. Nanoindentation evaluations overcome this problem and UV effects (in the case of this study) on properties such as modulus and hardness are clearly demonstrated.
