METALLIZATION AND SURFACE COATING SOLUTION ON GLASS FILLER HIGH PERFORMANCE AMORPHOUS POLYMER COMPOSITIONS

摘要

Provided are a product comprising a substrate, a first layer disposed on the substrate ,and optionally a second layer disposed on the first layer and a producing method thereof. The substrate comprises a polymer composition comprising: a) 35 -85 wt % of high- heat amorphous polymer having a glass transition temperature of at least 180 degrees Celsius; b) 10- 50 wt % filler selected from glass fiber, glass flake , glass bead and the combinations; and c) 0- 10 wt% at least one additive selected from a flow promoter , a thermal stabilizer , a mold release agent. The first layer and the second layer are independently selected from a metallized coating and a polymeric coating. The product has a Liquid Particle Count less than 1, 500 particles / cm2 and an EMI shielding effect higher than 30 dB.
