Today we’re going to discuss the difference between Polyurethane body kits and ABS plastic body kits. A lot of you wonder the difference between these two things.

Polyurethane, or commonly referred to as urethane, is a very popular material for car body kits. This material is more difficult and costly to produce, therefore it is a bit more costly, but like we’ve mentioned in previous blogs, it is much more flexible than fiberglass meaning that it’s easier to install and more durable. Also, the as-delivered fit and finish of polyurethane is superior than fiberglass. It’s much easier to ‘coax’ polyurethane into position during installation without fear of cracking or breaking the body part. One thing to remember is that polyurethane is heavier than fiberglass so you may not want to put it on a car that you’re racing.

With ABS plastic, you get a thermoplastic that’s made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The result of this is a material that combines the strength and rigidity of acrylonitrile and styrene polymers with the ruggedness of the polybutadiene rubber. When you use ABS plastic, you get a material that is impact, chemical, and heat resistant. Plus, ABS plastic is very widely used by OEM for body panels. Much like polyurethane, ABS plastic also has superior fit and finish that is found to be more expensive than fiberglass. It’s a little less flexible than polyurethane, but it’s found to be easier to paint.
