Which kind of engineering plastics is used for plastic test tube rack?
First of all I think must confirm the requirements of test tube commonly used in chemical and medical, acid and alkali corrosion resistance; it should be considered a medical and environmental protection, many materials have special specifications of medical grade; and then to consider the high and low temperature; and to consider the problem of density of general PP density is less than 1; finally considering the price; on the market mostly to do with these materials, PP, PMMA, PTFE, stainless steel, aluminum and other materials.
This depends on your product requirements, such as: toughness, strength, transparency, corrosion resistance, pressure (voltage), flame retardant, insulation and other materials of different properties and uses are not the same
HDPE: cheap, light and inert
