Thermoforming is the process of moulding huge sheets of thermoplastics around a specialised tool to get the required output. Choosing the proper plastic materials for custom plastic products and components is critical to achieving the best results for our customers. These soften and can be melted into a fluid when heated, but because no chemical changes occur, they can be moulded and recycled without affecting the plastic's qualities.
Best-known Raw materials
1. PVC (Polyvinyl chloride):
It's a different type of plastic with the properties crucial for effective thermoforming. It's a low-cost material with a wide range of applications, depending on the additives employed.
2. HIPS:
For numerous reasons, high impact polystyrene, or HIPS, is the most commonly used thermoforming material. HIPS is a low-cost material with a high melting point and is particularly malleable due to the addition of rubber additives, making it easy to shape and mould. Once formed and cooled, this smooth, glasslike material is impact resistant too.
HMPWE –
This material has strength, is chemically resistant, and can withstand punctures.
KYDEX (Blend of PMMA/PVC) –
It is an excellent all-purpose material for general application. Chemicals and strong blows do not harm it. It comes in a variety of colours and patterns.
ABS:
ABS (acrylonitrile, styrene, and butadiene) is a tough, impact-resistant plastic that can withstand chemical and UV exposure. Furthermore, it is remarkably elastic and flexible. Because of these characteristics, as well as its low cost and ease of manufacture, it is a widely used thermoplastic.
Acrylic-
Acrylic is a thermoformable, transparent, flexible, and damage-resistant substance. It softens at high temperatures but doesn't become liquid until around 320 degrees, making it an excellent heat shaping material. Because it's an excellent substitute for glass.
LEXAN –
There is a lot of flexibility, is fire, blemish, and can withstand a variety of environmental conditions.
Royalite –
This material is long-lasting, with strong impact and tensile strength. It also performs well at both high and low temperatures.
RPET-
It is Reprocessed Polyethylene Terephthalate. This is a common material used in food packaging. It is simple and inexpensive. If necessary, FDA certification can be obtained.
TPO (Thermoplastic PolyOlefin) –
This is a material with high-gloss finish and has good impact properties. It is good for outdoor applications. However, it is difficult to form, particularly for those applications where we require deep draw shapes and structures.
PC (Polycarbonate) –
The impact strength of this material is remarkable. It is transparent and highly resistant to very high temperatures.
Pennite –
It is glass filled nylon. This is cost-effective, tough and sturdy substance.
PETG (Polyethylene Terephthalate Glycol) –
This material is transparent and has high impact resistance. It also takes any shape beautifully. In the event that medical-grade material is required, it is readily available too.
PEI (Polyetherimide Ultem) –
This is a substance that can withstand extremely high temperatures. It has a natural amber tint and can be easily autoclaved.
PET (Polyethylene Terephthalate) –
This is a common material for the food packaging business. It is simple and is dirt cheap. And if necessary, FDA certification can be obtained.
PP (Polypropylene) –
This material is chemically resistant to a high degree. It is robust and has high impact resistance. It performs well at higher temperatures, although it is not as dimensionally stable as other ones.
