Vinyl and nylon are two common chemical materials that are widely used in our daily life and insulated terminals. Vinyl and nylon insulated terminals have different characters so that have different functions in different use.Therefore, how to select and evaluate vinyl and nylon insulated terminals correctly in real practice becomes much more necessary. In this short article, we will show you the differences between them and the conditions suit them respectively, hoping it could help you to make decision to some extent.

The introduction of vinyl and nylon terminal connector
Vinyl/PVC Terminal Connectors
Polyamide, commonly known as Nylon, with an English name of Polyamide (referred to as PA) and a density of 1.15g/cm3, is a general term for thermoplastic resins. Vinyl connectors have a sheath made by Polyvinyl Chloride plastic, most commonly known as PVC. While the insulation on these terminals is able to protect against short circuits, there is little other benefit to choosing this connector when making a repair. The wires being repaired remain exposed to the elements and can quickly corrode. The strength of this connection is dependent on the strength of a single crimp. Not only that, the insulation becomes brittle and cracks as it ages, a process accelerated by sun exposure. These connectors are the least expensive choice, providing a quality reflective of the price.
Nylon Terminal Connectors
Most household plastics are made of carbon and hydrogen. PVC differs in that it contains chlorine (about 57 percent by weight) in addition to carbon and hydrogen. Like vinyl connectors, nylon terminals do not protect the wires from corrosive elements, but nylon terminals are usually designed to be crimped twice. Therefore, nylon terminals are stronger than vinyl connectors as the double-crimp delivers additional tensile strength and strain relief against wire pull-out. The nylon itself is also a much more durable insulation than PVC. However, without a seal, the tougher insulation does nothing to pro-long the life of the wire.
The pros and cons of vinyl and nylon terminal connector
Vinyl Insulated Terminals:
Pros:
-Easy crimp on installation
-Usually the cheapest insulated option
-Wide selection of options
-Commonly available
Cons:
-Not a sealed connection so they can be prone to corrosion
-Wires can be prone to pulling out
-Crimp area is not visible, so it can be hard to determine if you achieved a good crimp
Nylon Insulated Terminals:
Pros:
-Easy crimp on installation
-Nylon insulation is more flexible and less prone to cracking than Vinyl
-More chemical resistant than vinyl
-Most can be 'double-crimped' on the wire and the insulation, providing a stronger connection.
-Semi-Translucent insulation makes it easier to see if you’ve made a good connection
-Wide selection of options
Cons:
-Wires can be prone to pulling out
-More expensive than vinyl
-Not a sealed connection so they can be prone to corrosion
The choosing when in real practice
The hardest choice a technician has when joining two wires together is choosing the right insulation for the wiring application.
l Vinyl/PVC connectors have insulation that is able to protect against short circuits, but there is little other benefit to choosing this connector when making a repair.
l Nylon terminals are more durable than vinyl/PVC connectors and are stronger as the double-crimp delivers additional tensile strength and strain relief against wire pull-out.
In a word, we generally compare these two different materials of terminal connectors, figuring that both have their own advantages and disadvantages. Therefore, you also need to pay more attention to the choose of the materials. Hope through this article, you make the correct determinations about which insulated terminal is more suitable when joining two wires together.
