Why Are Luxury Car Owners Switching To TPE Floor Mats?

In the adult world, apart from family, the longest companion is often the car that provides shelter from wind and rain. Everyone has their own unique emotional connection to their car, and the ways they protect it vary greatly.

Take car floor mats, for example. The original intention is to protect the interior and make cleaning easier. However, as car prices rise, people have become increasingly meticulous about their vehicles. Initially, factory-installed mats were just to prevent dirt, but now fully enclosed mats have become popular in China, to the point where people almost want to wrap the entire cabin.

In the automotive cultures of Europe and America, where car culture is more developed, large enclosed leather mats have never been popular. Instead, rubber or TPE (thermoplastic elastomer) mats are commonly used. Many car manufacturers, such as BMW and Volvo, even develop their own TPE mats.

TPE mats are more environmentally friendly compared to traditional rubber or leather mats. Their design is relatively refined, avoiding interference with the accelerator or brake pedals, and they are easier to clean.

Currently, TPE mats are divided into two manufacturing processes: injection molding and vacuum forming.

In international markets, many TPE mats use vacuum forming, while original car manufacturers exclusively use injection molding.

The cost of developing a mold for vacuum forming is around 10,000 to 20,000 RMB per car model, whereas injection molding costs about 300,000 RMB per model.

First, let’s discuss the differences between injection molding and vacuum forming:

Differences in raw materials
Injection molding requires 100% pure TPE material for production, while vacuum forming often mixes TPO or TPV with TPE-like materials. In terms of material purity, vacuum forming falls short of injection molding.

As a result, one-piece injection-molded TPE mats have a softer, more rubber-like texture and provide better foot comfort.

Vacuum-formed products, on the other hand, tend to be harder, more plastic-like, and can make the heels feel fatigued during long drives.

Differences in durability
Injection-molded TPE mats are resilient. If they deform over time, pouring boiling water over them or leaving them in the sun for a while can restore their original shape and fit.

Vacuum-formed mats, however, may start to curl at the edges after 1–2 years of use, and this deformation cannot be reversed.

The reason for these differences lies in the processes:

Injection molding involves melting granular raw materials at high temperatures in an injection molding machine before shaping them in a mold.

Vacuum forming starts with a flat sheet of material, which is then heated, softened, and suction-formed onto a mold to cool and set.

In other words, injection-molded products inherently have their intended shape, while vacuum-formed products only take shape on one side. Naturally, the latter’s ability to recover is far inferior to the former’s.
