polymers
-
urea formaldehyde
rigid,hard,brittle,heat resistant,excellent insulator.
powder,granules and preforms
-
polyester resin
ridgid,brittle,good insulator and good chemical resistance
Thick liquid,usually used with a catalst to harden resin and can be cloured through use of pigments,
Can be used with glass fibres to make lightweight and strong products. can be polished to a high finish and can chip if dropped.
-
Biopol
forms are fibre,granules and sheet.
lightweight,good insulator,degrades over time when in contact with soil.
degrades in soil,can be injection molded and vacuum formed expensive and low resistance to impact.
