Mediprene TPE helps make ears happy

ELASTO, part of the HEXPOL TPE Family, have developed a Mediprene TPE compound which is being used in Happy Ears® - high-quality earplugs which combine a unique design with advanced noise reduction and sound reproduction.

Nowadays we experience a lot of background noise that can soon become an irritation. That is exactly why Happy Ears earplugs were created, to fulfil the needs of today without foregoing comfort, design and, first and foremost, function. Happy Ears are earplugs that are suitable for all individuals who spend time in places where noise-levels can be disturbing.

Ordinary earplugs can often muffle both lower and higher frequencies which can lead to a tinny, muddy sound. Happy Ears, on the other hand, give an average noise-reduction of around 20 dB at all frequencies. This means that the earplugs protect the ears from harmful noises as well as retaining sound quality and feeling   The unique construction – with a hardened “foot” at one end and a soft “leg” at the other – helps to preserve sound-quality whilst providing high levels of protection and comfort. Happy Ears are made from ABS in the core and Mediprene thermoplastic elastomers (TPE) on the outer surface.

Mediprene TPEs have been engineered to address the demands of the medical device industry. Representative grades have passed cytotoxicity tests according to ISO 10993-5 and biocompatibility tests according to USP Class VI. The materials are latex free, which reduces the risk of allergic reactions; Mediprene TPEs have been classified as non-sensitizers. This was a key factor in the decision to use Mediprene TPE in Happy Ears.

The softness of the Mediprene TPE compound means that when the earplug’s soft hat is placed in the outer ear, it automatically moulds itself according to the shape of the ear, becoming almost round. The soft material then tries to return to its original oval state and it is this which creates pressure against the outer ear canal. This pressure means that the Happy Ears earplug fits securely, thus preventing sound from reaching the eardrum.

Happy Ears combination of unique design and advanced materials helped them win the Swedish design competition ‘Object of the Year’ in 2012.
