capability of APC plus was proven at German molder Baumgarten automotive technics GmbH, which helped develop the new functionality.
Although bio-based polymers are a big trend in thermoplastics, Gotro points out that it is relatively new in thermoset
. "This is because with bio-based polymers it is much harder to make the cross-linked network required for thermosets
," he says.
In order to prepare the flame retardant epoxy resins thermosets
, the PPBAP with different composition, epoxy resins, and the curing agent (m-phenylenediamine) were mixed homogeneously by a mechanical stirrer at 90[degrees]C with an equivalent ratio of epoxide/N-H= 1/1.
In this role, Arnold is responsible for planning and implementing sales and product development programs targeted towards existing and developing thermoset
markets within the Americas.
Wilczewski agrees that thermosets
are suitable for contemporary molding processes, but notes that rejection molding may not be the best fit for all appliance applications.
He led development of key proprietary technologies currently sold in the coatings and thermoset
Patent 8,653,150 (February 18, 2014), "Method for Decomposing Thermoset
Resin and Recovering Decomposition Product," Takumi Izumitani, Takaharu Nakagawa, Masaru Hidaka, Keishi Shibata, and Junko Matsui (Panasonic Corporation, Osaka, Japan, and International Center for Environmental Technology Transfer, Mie, Japan).
"And now, by transferring technology and expertise from our other locations, we've entered a class of suppliers who can offer certified thermoset
and thermoplastic operations, which is especially hard to find in Mexico markets."
Determination of rheological parameters of thermoset
material under process-like conditions is introduced.
The major challenges with this approach are to achieve suitable mixing/compatibility of the thermoset
components throughout the thermoplastic prior to curing and to avoid significant phase separation during crosslinking of the thermoset
components (kinetic control).
Patent 8,404,310 (March 26, 2013), 'Thermoset
Dampener Material," Martine Rousse and Ludovic Valette (Dow Global Technologies LLC, Midland, Michigan, USA).
Besides up to 70% weight savings compared to metals such as stainless steel, aluminum, and titanium, the innovative composite manufacturing process used by Tri-Mack provides several benefits leading to faster part manufacturing cycle times compared to thermosets
composite parts typically take several hours to complete," said Tom Kneath, Director of Sales and Marketing at Tri-Mack.
