RTP Company Introduces Glass Reinforced, Non-Halogen, Flame Retardant PTT Material


WINONA, MINNESOTA, USA - December 3, 2001- RTP Company, www.rtpcompany.com, in conjunction with Epcos AG -a German manufacturer of electronic components, has developed a commercial line of glass reinforced, non-halogen, flame retardant polyester compounds. Based on PTT (polytrimethylene terephthalate), this product line is available with glass levels of 10 to 33%.

RTP Company developed this compound in response to both the industry's and Epcos' call for a halogen free, eco-label compliant polyester compound for their coil former (bobbin) application. "We had started research and development on an eco-friendly, flame retardant, reinforced polyester prior to our work with Epcos. Although RTP Company has observed demand for such a product, no strong candidates are currently available on the market today." Stated Paul Killian, Product Manager of Flame Retardant Materials at RTP Company. " When we found a customer that was interested in sampling our research, we found the type of industry feedback that you cannot get with laboratory trials."

Used in many modern, high performance technologies, these applications have specific performance requirements. The result was an RTP 4700 series material. Boasting a Flexural Strength of 23,000-psi (158 MPa) and a Dielectric Strength of 500 V/mil, this product successfully passed Epcos' internal testing. Quality evaluations included an Epcos crush test and stringent electrical tests. The exceptional strength and stiffness properties, as well as a HDT of 410°F(210°C) @ 264(1.82 MPa) gave Epcos the performance their application required.

"We were looking for a halogen-free composite with a UL 94 VO listing. We were also looking for the technical competence of RTP Company." Commented Josef Sedlmeier, Director of Product Marketing and Design Accessories at Epcos AG. "RTP Company gave us fast response, competent technical people, flexibility, and they sampled material according to schedule. We chose RTP Company on a third party recommendation and would chose them again.
