Diallyl Phthalate - DAP Long Glass Fibre Reinforced

Mar 30 2001

Advantages

Best tensile strength, flexural modulus, notched impact strength and heat distortion temperature compared with other modified grades of DAP.

Disadvantages

As with other glass filled DAP mouldings, can be anisotropic with a tendency to warp. Expensive compared with other filled grades of DAP.
