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.


Nylons are one of the most common polymers used as a fibre. Most people know Nylon for its applications in clothing but it is also found in other places in the form of a thermoplastic. It is well known for being stable and adaptable with two main types used throughout the automotive and electrical appliance industry.

Nylon 6 is well known for its high impact strength and as such is used in compounds that will later be used for items like engine covers, radiator grills, wall plugs, electric tool casings and turn signal indicators. Nylon 66 on the other hand has a higher heat resistance and stiffness making it suitable for applications that include gear box parts, coolant hoses, cable straps, oil pan parts etc.


Polycarbonate plastics are a naturally transparent, easily mouldable thermoplastic. Polycarbonate polymers are used to produce a variety of materials. It is particularly useful for items that need to be impact resistant and transparent. It is commonly used for plastic lenses in eyewear, medical devices, automotive parts, protective gear, digital disks etc.

As mentioned before polycarbonate is very mouldable. It can typically be formed at room temperature without cracking or breaking. The most well-known polycarbonates are manufactured by SABIC under the name Lexan and Bayer Material Science under the name Makrolon.
