Resin is a solid or highly viscous substance that is typically convertible into polymers which are then used to make plastics. While some resins occur naturally others can be synthesized depending on the end product.

When it comes to plastic manufacturing there are many resins that can be used, in this two-part post we’ll share five of the most common types.

Acetal

Acetal is a thermoplastic that is well known for its strength and stiffness. Some of its common characteristics include good fatigue life, low moisture sensitivity, high resistance to solvents and chemicals and good electrical properties. Acetal is most commonly used in automotive applications, gears, bearings, handles, business equipment etc.

Polyester

Polyester is another material popular in the clothing world but it also has applications for plastic products. There are two classes of polyesters, thermoplastics such as polybutylene terephthalate (PBT) and polyethylene terephthalate (PET), and thermosets. This type of resin is commonly found in sheet moulding, and it is often used in kitchen and restaurant settings where surfaces require periodic washing.

Copolyester

Copolyester are formed when polyesters are modified using diacids and diols. Copolyesters are well known for their strength, clarity, versatility and flexibility. They can be used in a wide variety of applications. Copolyester resins are effective for packaging applications, and they are frequently used in the manufacture and packaging of consumer goods such as toys and pens. The medical packaging, home appliances and cosmetics industries, among others, rely quite heavily on copolysters.
