More rigid but more brittle than phenolics. Weaker than allylics and lower resistance to cracking around inserts. Fungus resistant but attacked by alkalis and strong acids. Excellent long term stability. High heat distortion temperature.
Limitations are that applications are confined to electrical or decorative products.
Electrical properties not maintained under severely humid conditions. Low moulding pressures. Good color stability but restricted color possibilities. Lower cost than allylics but more expensive than phenolics and melamines. Trays, boats, sinks and bathroom fittings.
