Tritan for audio

Tritan™ engineered polymers have proven to be durable materials that minimize resonance of cabinets and enclosures, enhancing long-term listening experiences. By reducing housing resonance and interference, Tritan also improves active noise cancellation and prevents feedback and feed-forward systems from becoming unstable.

Advanced housing materials

While continuing to introduce new audio technology, the industry has had to wait for innovative housing materials to keep pace. Here are a few of the ways Tritan and Tritan^™ Renew enhance user experience in audio devices:

Reduce resonance within enclosure
Improve active noise cancellation
Prevent feedback and feed-forward system instability by reducing interference from the housing

These advanced materials also reduce load on digital signal processing (DSP) in high-end speakers by:

Minimizing computational load through resonance removal, leading to longer battery life
Requiring less computing power from the PCB to mitigate costs
Increasing the efficiency of speaker/microphone systems by reducing echo
Allowing for higher sound pressure levels (SPL) in speaker systems that incorporate microphones by reducing echo and reverberation

Plus, Tritan Renew gives discerning music lovers many sound reasons to support sustainability without compromising their high acoustic standards.

Discover Tritan Renew

Tritan Renew from Eastman helps improve acoustic performance with the same noise damping benefits as the original Tritan — but with an emphasis on sustainability. Tritan Renew is the first material made from Eastman’s molecular recycling technology — with up to 50% certified recycled content.* So Tritan Renew reduces the plastic waste going to landfills, incinerators and the environment.

*Certified recycled content allocated using ISCC mass balance.
