Polyester - DMC; Low Profile

Advantages

Very low mould shrinkage, improved surface appearance and lowest density compared with other polyester DMC’s.

Disadvantages

Lowest tensile strength, heat distortion temperature, maximum operating temperature, flexural modulus and dielectric strength compared with other polyester DMC’s.
