The plastic industry has always lagged behind the most exciting modern innovative products. Plastics enable us to develop advanced medical skills, more efficient vehicles and high-tech aerospace products.

However, many of the changes brought about by plastics are not so attractive, but are equally important. adopt Electric vehicle helmet A recent study by Rebecca Ivers, a researcher at the George Global Health Institute in Australia, found that electric vehicle helmets generally made of various plastics can reduce the risk of head injuries by 63-88%.

Epitome of plastic industry

Electric vehicle helmet Today's focus is the epitome of the overall history of the plastic industry: innovative companies have made use of plastic materials and the continuous progress of production companies to produce more and more effective products.

Pre plastic era: fashion, not safety

Before plastic entered the helmet scene (in the mid-1970s), riders proposed some methods to maintain themselves (most of which were ineffective). The most popular sweater, known as the driver's sweater, is just filled with leather strips, one of which is wrapped around the head, and two of which are covered on the top. These helmets have no effect, and are more used as fashion items and the origin of mind assurance.

Polystyrene EPS helmet

The innovation to truly transform the helmet industry is the use of expanded polystyrene (EPS) foam. Although helmets had hard plastic shells as early as the 1960s, innovators did not have the idea of maintaining non disposable human skulls with destructible plastic materials until the mid-1970s. These plastic materials will be the first to be affected. Whereas EPS can reach 98% of the market.

Helmet shell: overweight or need reinforcement?

For most of the 1970s, helmets were made of EPS foam inside Lexan plastic housings. The housing provides a lubricated, consolidated outer surface that can convey impact throughout the helmet. However, it is difficult for Lexan to develop a ventilation system. This puts manufacturers in a dilemma - creating safer helmets with heavy housings.

In 1990, the manufacturer of this solution began to use PET (milk jug plastic) to make lightweight but effective helmet shells. Since then, helmet manufacturers have continued to innovate and develop EPP foam materials, which can heal after slight impact and add overall durability.

I hope this brief summary indicates that the characteristics of electric vehicle helmet manufacturers are synchronized with the innovation of the entire plastic industry.
