Transparent thermoplastic composition containing polytetrafluoroethylene particles |
摘要 |
The thermoplastic composition according to the invention for shaped light-scattering articles, based on a transparent thermoplastic formed from (meth)acrylic (co)polymer and on light-scattering particles, comprises polytetrafluoroethylene (PTFE) particles or a mixture of PTFE particles and particles of a mineral and/or organic substance, these light-scattering particles having a mean size of 0.5 mum to 200 mum and a refractive index which differs from that of the transparent thermoplastic by at least ±0.05 and being used in an amount, with respect to the total composition, of 5 ppm to 2000 ppm by weight. Application to light display devices and to flat light screens comprising a sheet obtained from the composition.
