Generally speaking, the thermal and/or chemical performance of machinable thermoplastics depends on their Tu. It should be noted that the Tu of a thermoplastic is below its melt temperature (Tm), i.e. the temperature at which the material becomes liquid. In terms of physical properties, the glass transition temperature (Tg) of a thermoplastic represents the temperature interval over which the material passes from a rubbery state to a glassy state, i.e. a solid state.
GRANDO requires all its suppliers of thermoplastics to have their products certified according to the two European REACH and RoHS directives concerning the use of hazardous substances.
