Polymer
The proper term for a plastic metal
1 of 31
Cellulose
A constituent part of timber. Aprox 55% of a tree is made up of this
2 of 31
Heat treatment
A term given to a range of processes using heat to cause a change in a metal's properties by making changes to the internal structure of the material
3 of 31
Biodegradable
A term given to materials that will break down with the aid of natural processes, such as sunlight and rain
4 of 31
Renewables
Materials that are extracted from managed sources, such as pine from forests where trees are replaced by saplings as they were felled.
5 of 31
Biopol
A polymer made from natural cellulose, which can be used to make biodegradable packaging
6 of 31
Degradation
The deterioration of polymers
7 of 31
Injection moulding
A method of processing thermoplastic materials. Products generally have complex 3D shapes
8 of 31
Blow moulding
A process of manufacturing thermoplastic materials into re-entrant shapes with a single opening. Such as drinks bottles, or detergent bottles
9 of 31
Parison
The extruded tube of thermoplastic material used in the process of blow moulding
10 of 31
Rotational moulding
A method of moulding thermoplastic polymers that involves plastics in powder form taking the shape of a fully enclosed mould as the mould passes through a heating section. The material becomes ridged as the mould is cooled
11 of 31
Thermoforming
A form of vacuum forming. The main differences are that air pressure and an additional female mould assist the forming process, to enable great detail to be achieved
12 of 31
Vacuum forming
A process where sheets of thermoplastic polymer are heated and formed to shape by the application of a vacuum to 'pull' the material down onto the simple mould
13 of 31
Calendaring
A process used to manufacture thermoplastic sheet.
14 of 31
Line (or *****) bending
A method of processing sheet materials, in particular thermoplastics, limited to process simple shapes
15 of 31
Catalyst
A substance that increases the rate of a chemical reaction without itself changing the reaction
16 of 31
Compression moulding
The manufacturing process generally used for processing thermosetting polymers
17 of 31
Cross-link
The fixing together of the long-chain molecules within a polymer
18 of 31
van dee Waals bond
A type of atomic bonding found in thermoplastics, it is this electrostatic bond that allows the re shaping of thermoplastics when heated
19 of 31
Rigid cross-link
Found in thermosetting plastics and elastomers. More rigid bond that van dee Waals bond, and do not react to the application of heat
20 of 31
Fibre optics
Glass fibres that are used to transmit data using pulses of light
21 of 31
Sprue
A vertical channel in a mould through which plastic or molten metal is introduced or out of which it flows when the mould is filled
22 of 31
Fibre-reinforced polymers
Combining woven material, such as carbon fibre, with a polymer resin and a catalyst to make a strong, lightweight material
23 of 31
Fibre-reinforced composite
Material that is made up of resins and fibres.
24 of 31
Particle-based composites
Composites that consist solely of particles of two or more different materials
25 of 31
Warping
Deforming in timber due to uneven drying
26 of 31
Laying up
The act of laminating
27 of 31
Matt
Loosely woven fibres that make up the material once resins have been added
28 of 31
Cermet
A mixture of a metal and a ceramic
29 of 31
Laminate
Building up layers of mateirals
30 of 31
Corrosion
The deterioration of metals
