Basf To Launch New Ppa Ultramid At Chinaplas
Market Expertz | May 15, 2019
BASF is set to introduce the new PPA Ultramid Advanced T2000 at the Chinaplas 2019 to be held in Guangzhou. The compound group is based on PA 6T/66 and offers a combination of exceptional mechanical and dielectric strength at high temperatures, which is most beneficial for connectors in the electrical and electronics (E&E) sector. The compound also has a partially aromatic chemical structure, which makes it the ideal solution for parts that need high, constant stiffness and strength that can withstand under a broad series of temperature. Ultramid is resistant to heat and humidity and also exhibits some flame-retardant characteristics. These properties make the compound highly suitable for applications in the E&E connector industry where high resistivity is needed and in the transportation sector where it is essential to maintain the strength of the materials under any temperature or in any environment.
The Ultramid is broadly used in several markets from the E&E to the automotive industry. The compound is used in delicate flame-resistant connectors through structural laptop parts, switches, and miniature circuit breakers. Ultramid also offers a high flowability for injection molding that facilitates the thin-wall design and excellent surface quality. It also improves part integrity making structures more durable, making them able to withstand extreme heat. The PPA also displays enhanced impact strength similar to a standard PA66 and a reduced water uptake compared to standard aliphatic polyamides with a high melting point at 310°C and a heat deflection temperature that is less than 280°C. These properties make it the ideal material for lead-free soldering without partial deformation. The compound can be efficiently processed because of its superior flowability that is significantly higher than other high-temperature polyamides without affecting its flexibility or strength. The PPA is also compatible with several post-processing methods including welding and laser marking.
BASF has also developed a unique series of flame-retardant grades reinforced with 30 to 40 percent glass fibers and with UL 94 V-0 rating available in all colors. Additionally, many grades offer reinforcement levels between 30 to 50 percent glass fibers along with improved impact resistance, which is available both uncolored and laser-markable black. The company also provides different heat stabilizers for various requirements of individual applications.
