Insufficient heat during cure will result in a network with incomplete polymerisation, and thus reduced mechanical, chemical and heat resistance.
32.
Glass-which consists of sand and additives for heat resistance-acts like a solid, but has many of the properties of liquids.
33.
Borosilicate is also a material of choice for evacuated-tube solar thermal technology, because of its high strength and heat resistance.
34.
Its usage is unknown, but its adiabatic capacity suggest some kind of insulating usage ( but not heat resistance ).
35.
Such flaps require greater strength due to the power of modern engines and also greater heat resistance to the hot exhaust.
36.
However, mutants resistant to heat but lacking dipicolinic acid have been isolated, suggesting other mechanisms contributing to heat resistance are at work.
37.
While it was one of the cheapest high-temperature resistant plastics, processing was difficult and the impact and heat resistance decreased with time.
38.
Also mechanical properties are changed : stress cracking resistance and toughness in the cold rise, whereas yield stress and heat resistance decrease.
39.
IMCO Carbide Tool products begin with " blanks, " or ultra-fine micrograin carbide, because of its extreme hardness and favorable heat resistance.
40.
These uses often require exceptional performance, strength or heat resistance, even at the cost of considerable expense in their production or machining.
