Vacuum forming is a process that involves heating a sheet of plastic until it becomes pliable, and then using a vacuum to form it over a mold. The most commonly used materials for vacuum forming include:
- Acrylic (also known as polymethyl methacrylate or PMMA)
- Acrylonitrile butadiene styrene (ABS)
- Acrylonitrile-styrene-acrylate(ASA)
- Polyethylene (PE)
- Polypropylene (PP)
- Polystyrene (PS)
- Polyvinyl chloride (PVC)
- High-impact polystyrene (HIPS)
- Thermoplastic elastomers (TPEs)
- Fluoropolymers (such as PTFE and FEP)
- Polycarbonate (PC)
- Polyethylene terephthalate (PET)
It is worth noting that vacuum forming is generally used for thermoforming thermoplastic materials, rather than thermosetting materials like epoxies or polyurethanes. These materials do not become pliable when heated and cannot be formed using the vacuum forming process.
Acrylic (also known as polymethyl methacrylate or PMMA)
Acrylic is a popular choice of material for vacuum forming because of its excellent optical clarity, strength, and durability. It is also easy to work with and can be molded into a wide range of shapes and sizes.
There are many advantages to using acrylic for vacuum forming, including:
- Excellent optical clarity: Acrylic is known for its excellent clarity, which allows for the creation of transparent or translucent products. This makes it ideal for applications where visibility is important, such as display cases, signage, and lighting fixtures.
- Strength and durability: Acrylic is a strong and durable material, making it suitable for applications where the finished product will be subjected to heavy use or outdoor conditions. It is also resistant to UV light and chemicals, which helps to extend its lifespan.
- Easy to work with: Acrylic is easy to cut, drill, and shape, making it suitable for a wide range of applications. It can also be easily glued or solvent welded, allowing for the creation of seamless joints and finishes.
- Wide range of color options: Acrylic is easy to dye or paint, which allows for a wide range of color options. It can also be produced in a variety of different shades and tints, including clear, frosted, and opaque.
- Versatility: Acrylic is a versatile material that can be used for a wide range of applications, including prototypes, custom parts, and large-scale production runs. It is also suitable for use in a variety of industries, including medical, retail, automotive, and more.
Despite these advantages, there are also some potential drawbacks to using acrylic for vacuum forming. One potential disadvantage is that it has a relatively high melting point, which may require longer heating times and higher temperatures. It is also more expensive than some other types of plastic, such as polystyrene or PETG.
Despite these potential drawbacks, acrylic is still a popular choice for vacuum forming due to its excellent properties and versatility. Whether you are looking to create prototypes, custom parts, or large-scale production runs, acrylic is a reliable and effective material for vacuum forming.
ABS (Acrylonitrile Butadiene Styrene)
ABS (Acrylonitrile Butadiene Styrene) is a type of plastic that can be used in vacuum forming. Vacuum forming is a process in which a sheet of plastic is heated until it is pliable, and then a vacuum is used to suck the heated plastic onto a mold. ABS is a good choice for vacuum forming because it is a strong, durable material that can be easily molded into various shapes and sizes. It is also resistant to UV light, water, and chemicals, which makes it suitable for outdoor use. However, ABS has a relatively low melting point, so it may require higher heating temperatures and longer heating times to make it pliable enough for vacuum forming. It is also not as optically clear as other plastics such as acrylic, so it may not be suitable for applications where clarity is important.
There are several advantages to using ABS for vacuum forming, including:
- Strength and durability: ABS is a strong and durable plastic that is resistant to impact and stress. It is also resistant to UV light, water, and chemicals, making it suitable for outdoor use.
- Easy to work with: ABS is easy to cut, drill, and shape, making it suitable for a wide range of applications. It can also be easily glued or solvent welded, allowing for the creation of seamless joints and finishes.

- Good machinability: ABS can be machined using a variety of methods, including milling, turning, and grinding. This makes it suitable for applications where precise dimensions and tolerances are required.
Despite these advantages, there are also some potential drawbacks to using ABS for vacuum forming. One potential disadvantage is that it has a relatively low melting point, which may require higher heating temperatures and longer heating times to make it pliable enough for vacuum forming. It is also not as optically clear as other plastics such as acrylic, so it may not be suitable for applications where clarity is important.
Despite these potential drawbacks, ABS is still a popular choice for vacuum forming due to its excellent properties and versatility. Whether you are looking to create prototypes, custom parts, or large-scale production runs, ABS is a reliable and effective material for vacuum forming.
Acrylonitrile-styrene-acrylate(ASA)
ASA, or acrylonitrile-styrene-acrylate, is a type of thermoplastic polymer that can be used for vacuum forming. It is known for its resistance to UV radiation, which makes it an attractive material for outdoor applications. ASA also has good impact resistance, chemical resistance, and dimensional stability, making it suitable for a variety of applications in industries such as automotive, construction, and packaging. It is often used as an alternative to ABS (acrylonitrile butadiene styrene) because it has improved weatherability and color stability. However, ASA can be more expensive than ABS and may require more specialized processing conditions.
ASA (Acrylonitrile Styrene Acrylate) is a type of plastic that can be used in vacuum forming. ASA is similar to ABS plastic, with the main difference being that it has improved weather resistance due to the addition of an acrylate group.
There are several advantages to using ASA for vacuum forming, including:
- Weather resistance: ASA has improved weather resistance compared to ABS due to the presence of an acrylate group, which makes it more resistant to UV light, water, and chemicals. This makes it suitable for outdoor use and applications where the finished product will be exposed to the elements.
- Strength and durability: ASA is a strong and durable plastic that is resistant to impact and stress. It is also resistant to UV light, water, and chemicals, making it suitable for outdoor use.
