Polymer Enhancements Flashcards
1
Q
Polymer enhancements
A
- Lubricant
- Thermal antioxidants
- Pigments
- Antistatics
- flame retardants
- Plasticisers
- Fillers
- Biodegradable plasticisers
- Bio-batch additives
- Antioxidants
- UV light stabilisers
2
Q
- Lubricants
A
Makes molten polymer less viscous so moulding is easier
Moulding temp lower - saves energy
3
Q
- Thermal antioxidants
A
Prevent polymer oxidising/discolouring because of heat
4
Q
- Pigments
A
Particles added in molten state to change colour
5
Q
- Anti-statics
A
Reduces static charge
6
Q
- Flame retardants
A
Prevents combustion (eg plug sockets)
7
Q
- Plasticisers
A
Reduces how brittle object is
Eg added to LPDE in food wrap to stretch it
8
Q
- Fillers
A
Sawdust bulks product so less polymer needed
9
Q
- Biodegradable plasticisers
A
Polymers more flexible - inc plasticity
Breaks down easy
10
Q
- Bio-batch additives
A
Oxy/photo / hydro degradable to reduce degredation time
11
Q
- Antioxidants
A
Helps reduce decomposition / discolouration via air
12
Q
- UV light stabilisers
A
Prevent UV light discolouration
Eg outdoor toys
