The main impact absorbing material in a cycling helmet is, therefore, a moulded block of polystyrene foam, usually with a polycarbonatecovering. These materials are easily shaped - cycling helmets often have striking shapes to improve their aerodynamic performance. Manufacturing.
14/4/2020, · ABS plastic also has applications outside of the toy industry. It is a favorite material for children's clarinets and recorders, protective helmets and canoes. Its considerable shock-absorbent properties also make ABS plastic ideal for luggage, laptop cases and similar protective items.

There are several types of thermoplastics. ABS (Acrylonitrile Butadiene Styrene) ABS plastic is a thermoplastic blend which combines the strength and rigidity of certain polymers with the ruggedness of polybutadiene rubber. Because ABS plastic is chemical- and heat-resistant and offers good protection against dents, it's widely used in helmets.
Helmets made with PET shells will typically have smaller vents, because the lower strength shell material does not permit opening up larger vents and still maintaining the required level of impact protection. Hard shell helmets may have ABS plastic or fiberglass shells. We don't think those have been implicated as possible sources of problems.
Acrylonitrile Butadiene Styrene (ABS) is an opaque thermoplastic and amorphous polymer. “Thermoplastic” (as opposed to “thermoset”) refers to the way the material responds to heat. Thermoplastics become liquid (i.e. have a “glass transition”) at a certain temperature (221 degrees Fahrenheit in the case of ABS plastic).
10/7/2019, · Both ABS and polycarbonate are plastic, like much of the rest of your helmet. They Are Good Engineering Materials There are a few physical properties that make both ABS and polycarbonate useful for engineering. What makes them great for helmets is that they are resilient to impact, and can survive a wide range of temperatures.
