Overmolding for soft-touch designs
The medical industry has a great and growing demand for innovative soft-hard designs in devices, housings, and other equipment. A recent advance in liquid silicone rubber (LSR) technology makes it easier to satisfy this demand with medical grades of Eastman Tritan™ copolyester.
The advantages of Tritan are well-known to readers of this blog. Medical grades of Tritan offer a unique combination of properties including:
• Outstanding resistance to medical disinfectants and solvents
• Excellent impact strength and durability
• Made without BPA and halogens
• Excellent clarity and color retention after sterilization by ethylene oxide (EtO),
e-beam, and gamma irradiation
Polymer selection for durables applications
Brand owners and design engineers continue to find new ways to use Eastman Tritan™ copolyesters in a wide range of food contact and non-food contact applications.
Its unique combination of clarity, durability, hydrolytic stability, and heat and chemical resistance makes Tritan ideal for many applications, including:
Food contact applications
Non-food contact applications
Starting with your specific needs, Eastman can provide technical expertise and support to help determine the best grade of Tritan for your application.
Why specify medical grade polymers
It is critical for designers of innovative medical devices and packaging to have access to high-performance medical grade materials.
To ensure patient safety and long-lasting reliability, manufacturers depend on medical grade material suppliers like Eastman—not only to provide advanced, high quality raw materials but also to have capabilities and systems that help comply with medical protocols and regulations.
Manufacturers who specify medical grades of clear or opaque Eastman Tritan™ copolyester* know that Eastman will provide a high level of support throughout the regulatory journey to commercialization of a new product. Eastman’s world of experience helps ensure confidence and compliance in the areas of:

Many Medical hardware housing complaints. One new technology solution.
The increased use of aggressive cleaners, medical disinfectants, and disinfectant wipes is taking its toll on traditional plastics. Many handheld and bedside devices are becoming sticky, wearing thin in high-touch areas, or even cracking, crumbling, or shattering after only a few months of service.
The problem is that device housings that were designed just a few years ago are often made with materials that lack the right combination of impact strength and chemical resistance for today’s demanding medical environments.
In one of our most popular webinars, from November 15, 2016, we discussed the chemistry and stress behind these premature failures as well as how Eastman Tritan™ copolyester for medical housings is helping to prevent costly repairs and replacements. By replacing traditional housing materials with Tritan, you can improve patient safety and customer satisfaction.
Hot runner molding systems #2
False starts are costly-especially when setting up a hot runner system. Making changes after a hot runner mold is released for building are difficult, extremely expensive, and can have lasting effects on system efficiency.
Early collaboration between Eastman and OEMs, part designers, tool designers, molders, and the hot runner supplier is one of the greatest benefits of molding with Eastman Tritan™ copolyester. This teamwork helps:
- Reduce product development time
- Ensure processing efficiency
- Improve end-product quality
Food Industry and Chemical Resistance
Food for thought—compatibility with cleansers and disinfectants used in the food industry
Chemical cleaning and disinfecting are critical steps to guarantee food products have safe, below threshold levels of microorganisms that can reduce product shelf life and cause foodborne illness if too high.
Food contact parts are generally cleaned before disinfecting. This helps reduce microbial contamination but serves the more important purpose of increasing the effectiveness of the powerful disinfectant that follows.
Both sanitizing steps rely on chemicals that can crack and break plastic parts and even lead to their premature failure. Chemical attack also can cause surface etching that creates a favorable environment for microbe growth.
Testing demonstrates Eastman Tritan™ copolyester is significantly more compatible with cleansers and disinfectants than other polymers used in the food industry.
In case you missed our small appliance acoustics webinar—it’s now available on demand.
This 1-hour webinar shows where noise comes from and how a material change can help reduce it.
Noise is a turn-off. Quiet is a value-add. Consumers are willing to pay a premium for small appliances that provide robust performance-and do it with less noise.
