Diallyl Phthalate - DAP Short Glass Fibre Reinforced Reinforced

Mar 30 2001

Advantages

Good tensile strength, flexural modulus and elongation at break with the best combination of volume resistance and dielectric strength when compared with other modified grades of DAP.

Disadvantages

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