Polyester - SMC; High Impact

Advantages

Highest notched izod impact strength, tensile strength and elongation at break compared with other polyester SMC’s.

Disadvantages

Lowest flexural modulus, surface hardness and heat distortion temperature, highest mould shrinkage and density compared with other polyester SMC’s.
