What does (ER) stand for?
Epoxy resin, thermosetting
What does (UF) stand for?
Urea Formaldehyde, thermosetting
What does (PF) stand for?
Phenol formaldehyde, thermosetting
What does (MF) stand for?
Melamine formaldehyde, thermosetting
Define thermoforming
plastics that can be re- heated and therefore shaped in various ways, can be recycled
Define thermosetting
Once ‘set’ these plastics cannot be reheated to soften, shape and mould, can’t be recycled
What are some polymer additives?
Plasticisers, Pigments, Stabilizers, Fillers.
What is a plasticizer?
Plasticizers are substances added to plastics to make them softer and easier to shape.
What is a stabilizer?
Additives used to prevent degradation or deterioration of materials, typically by inhibiting reactions such as oxidation or UV degradation.
What is a filler?
Inert materials added to plastics to improve properties such as strength, stiffness, or density, or to reduce cost by displacing more expensive polymer materials.
What is a stock form?
the standard shapes and sizes in which a material is available
What are some different polymer stock forms?
What is anodising?
Anodising is a process that adds a protective layer to metals like aluminium to improve corrosion resistance and can also change its color.
What is electroplating?
Electroplating is a process where a metal object is coated with a thin layer of another metal using electricity. It’s used to improve appearance, corrosion resistance, or other properties of the object.
What is staining?
Staining is applying a colored finish to wood or concrete surfaces to enhance their appearance while preserving the natural texture and grain of the material.
What are vinyl decals?
Vinyl decals are adhesive stickers made from vinyl material. They are used for decorative purposes, branding, or signage on various surfaces like vehicles, windows, and walls.
What is galvanizing?
Galvanizing is coating steel with zinc to prevent rust and corrosion
What is plastic powder coating?
Plastic powder coating is a way to apply a durable and decorative finish by spraying and heating dry plastic powder on a surface.
What is polyurethane varnish?
Polyurethane varnish is a clear, durable coating applied to wood surfaces to protect them from scratches, moisture, and UV damage while enhancing their appearance.
What is spray paint?
Spray paint is a type of paint packaged in a pressurized can that is applied by spraying a fine mist of paint onto surfaces for quick and even coverage.
What is teak oil?
Teak oil is a protective finish made from natural oils that is applied to teak wood to enhance its natural beauty, provide moisture resistance, and protect it from the elements.
What is brush-on metal paint?
Brush-on metal paint is a type of paint designed for applying with a brush or roller to metal surfaces. It provides a protective and decorative coating, enhancing the appearance and durability of the metal.
What would staining be used on?
Wood or concrete surfaces in construction.
What would vinyl decals be used on?
Vehicles, windows, walls for decorative or branding purposes.
What would galvanizing be used on?
Steel structures and components to prevent corrosion
What would plastic powder coating be used on?
Metal surfaces for a durable and decorative finish.
What would polyurethane varnish be used on?
Wooden furniture, floors, and trim for protection and enhancement.
What would teak oil be used on?
Teak wood furniture and outdoor structures for protection and enhanced appearance.
What would brush-on metal paint be used on?
Metal surfaces like fences, gates, and machinery for protection and decoration.
What would anodising be used on?
Aluminium products like cookware, window frames, and automotive parts.
What would electroplating be used on?
Jewelry, automotive trim, and household fixtures.
What is a piezoelectric material?
Piezoelectricity, electrical charge built up in response to mechanical stress.
Phosphorescent
something that glows or emits light without heat after being exposed to light.
Photochromic
These are materials that change color when exposed to light.
Thermochromic
This refers to materials that change color with temperature fluctuations
