Polymer Enhancement 3.1.3 Flashcards
What are the reasons for adding Pigments to Polymers?
Added to poymers in molten stage to give colour
What are the reasons for adding Lubricants to Polymers?
Adding Wax or calcium reduces viscosity making it less sticky
moulding temperature becomes lower
What are the reasons for adding Antistatics to Polymers
Reduces the likehood of the poymer building up a static charge
What are the reasons for adding Plasticisers to Polymers
Allos plastic to become less brittle and hard. more elastic
What are the reasons for adding Fillers to Polymers
Bulks the product with materials so less polymers is required
What are the reasons for adding Bio degradable Plasticisers to Polymers?
Makes the polymer more flexible so means it degrades faster
What are the reasons for adding Thermal Antioxidants to Polymers?
Prevents polymer from oxidising due to excessive heat
What are the reasons for adding UV stabilisers to Polymers?
prevents polymer chains from breaking due to sunlight so their is no colour loss and brittleness.
What are the reasons for adding Bio-batch additives to Polymers?
Help reduce the degradation time from hundreds of years to months. e.g oxy dedegradable.
