Chemical compatibility is important when choosing materials for chemical storage or reactions, so that the vessel and other apparatus will not be damaged by its contents. For purposes of chemical storage , chemicals that are incompatible should not be stored together, so that any leak will not cause an even more dangerous situation from ...
Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic welding processes in that heating energy is generated by the chemical reaction between the solvent and thermoplastic, and cooling occurs during evaporation of the solvent ...
Failure is rarely associated with primary chemical agents, as these materials are anticipated to come into contact with the polymer during its lifetime, and thus compatibility is ensured prior to use. In air, failure due to creep is known as creep rupture, as the air acts as a plasticizer, and this acts in parallel to environmental stress cracking.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Polypropylene, highly colorfast, is widely used in manufacturing carpets, rugs and mats to be used at home. [47] Polypropylene is widely used in ropes, distinctive because they are light enough to float in water. [48] For equal mass and construction, polypropylene rope is similar in strength to polyester rope.
Polypropylene carbonate is soluble in polar solvents like lower ketones, ethyl acetate, dichloromethane and chlorinated hydrocarbons and insoluble in solvents like alcohols, water, and aliphatic hydrocarbons. It also forms stable emulsions in water. PPC allows the diffusion of gases like oxygen through it.
That same pungent, chemical smell had choked the air just a few miles away as the fire kept racing before dawn on January 8 through west Altadena, sending embers zipping through the air like bullets.
The following compounds are liquid at room temperature and are completely miscible with water; ... Chemical formula Name CAS number N 2 H 4: hydrazine: 302-01-2 HNO 3 ...
