POLISHING AND COMPOUND KIT

The polishing and compound kit is designed to be used with metals and thermoset plastics. The kit includes solid base polishing compounds that are transferred onto the polishing buff with the help of friction (high speed).

In the manufacturing process consisting of injection moulding, the type of plastic used is a thermoplastic. Thermoplastics have a low melting temperature compared to metals and thermoset plastics.

Common types of synthetic polymers found in thermoplastics (these plastics cannot be buffed using solid polishing compounds that involve friction):

• Low Density Polyethylene (LDPE) – Squeese bottles, toys, flexible pipes, insulation cover (electric wires)
• High Density Polyethylene (HDPE) – Bottles, plastic bags
• Polypropylene (PP) – Automotive parts, dishware
• Polyvinyl Chloride (PVC) – Lawn chairs, hand bags, raincoats
• Polystyrene (PS) – Petri dishes, CD case, plastic cutlery
• Teflon Polytetrafluoroethylene (PTFE) – Non-stick pans, membrane filters, thread seal tape
• Thermoplastic Polyurethanes (TPU) – Automotive instrument panels, caster wheels, power tools
• Nylon – Instrument strings, car components

Thermoset plastics (formed by means of a chemical reaction that cannot be melted) that can be polished using the kit:

• Epoxies
• Silicone
• Vulcanized rubber
• Polyester
• Polyurethane

To be able to remove hairline scratch marks from a thermoplastic’s surface, a liquid type polishing compound should be used.

We recommend using the Flexipads Liquid shine – Fine cut range together with a microfiber cloth or a polisher to polish the surface using very low friction.
