thermoplastic

A

bends when heated and retains bent shape (no plastic memory)

26
Q

thermoplastic
becomes brittle with age
may cause allergies
higher quality coated to seal surface and contain a UV inhibitor to prevent color fading
when left uncoated, plastic may absorb allergic substances

A

better for injection molding than cellulose acetate
less color stability
25% lighter than cellulose acetate

A

propionate

29
Q

epoxy resin
thermoelastic
30% lighter than cellulose acetate
might be an option for patients allergic to other plastic materials

A

Optyl

30
Q

bends when heated and returns to its original shape when reheated (plastic memory)

A

Thermoelastic
