AKROMID® A28 LGF 50 9 black (7705)
PA66
安科罗/开德阜(AKRO-PLASTIC)
产品描述
AKROMID® A28 LGF 50 9 black (7705) is an easy flowing PA6.6 with 50% long glass fibre reinforcement which leads to an extraordinary high stiffness and strength even at high temperature. The material distinguishes itself due to its isotropic mechanical properties as well as increased creep resistance and higher heat deflection temperature.
The excellent fatigue performance, high energy absorption in the event of a crash and low shrinkage make it the product of your choice for technical parts e.g. oil pan.
