Diallyl Isophthalate - DAIP Mineral Filled

Aug 16 2001

Advantages

Better flow properties and more uniform shrinkage; hence lower warpage than with glass-reinforced grades of DAIP.

Disadvantages

Lower tensile strength, flexural modulus, notched izod impact strength and heat distortion temperature compared with the glass fibre modified grades of DAIP.
