Urea-Formaldehyde Properties Flashcards
High tensile strength
maximum stress that a material can withstand while being stretched or pulled before breaking.
High flexural modulus
The ratio of stress to strain that a material can endure while bending before it yields.
High heat-distortion temperatures
At what temperature the material will begin to “soften” when exposed to a fixed load at elevated temperatures.
Mould shrinkage
When the volume of the molten plastic filled inside the cavity of a mold shrinks during the process of cooling and solidifying.
a property to do with surface
High surface hardness
Elongation at break
The ratio between changed length and initial length after the material breaks
Volume resistance
The electrical resistance of a body to a
current passing through its bodily substance.
