ECO-FRIENDLY FLAME RETARDANTS
A great deal of effort has been made to develop environmentally friendly flame retardants (FRs), which can replace halogen compounds . Phosphorus-based flame retardants are gaining attention as a nonhalogen-based flame-retardant system to resolve the environmental issues. Recently, another type of aromatic polyester, poly (1,4-cyclohexylene dimethylene terephthalate) (PCT), has received much attention as an engineering plastic having higher heat resistance and hydrothermal stability than PET and PBT. In the present work, we investigated the pyrolysis and fire behaviors of PCT by employing FRs. We showed technology of PCT resin composition with high color-resistance and heat-resistance comprising a nonhalogen FRs and a non-halogen FRs aid.
HIGHLY THERMALLY CONDUCTIVE POLYMERS
Thermal management is one of key technologies required to develop high end electric and electronic products. High thermal conductivity is quite demanding in order to ensure product reliability in semiconductors, electronics packaging, and thermal interface materials. One of the feasible practical methods to achieve high thermal conductivity along with good processability is to combine inorganic filler particles with a polymeric binder and construct a robust composite. The thermal conductivity of inorganic material primarily falls in 30-500 W/m K. On the other hand, the thermal conductivities of polymers are extremely low compared to those of inorganic fillers: normally 0.1-0.5 W/m K is found for the thermal conductivities of polymers. Therefore, it is essential to develop a polymer material exhibiting high thermal conductivity for solving the thermal management issues.
