In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.
Hypalon is a chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM) noted for its resistance to chemicals, temperature extremes, and ultraviolet light.It was a product of DuPont Performance Elastomers, a subsidiary of DuPont. [1]
It is known colloquially among chemists as the "Rubber Bible", as CRC originally stood for "Chemical Rubber Company". [2] As late as the 1962–1963 edition (3604 pages), the Handbook contained myriad information for every branch of science and engineering. Sections in that edition include: Mathematics, Properties and Physical Constants ...
The chemical resistance of a material or surface can be determined in compliance with ISO 2812 Paints and varnishes – Determination of resistance to liquids – Part 1: Immersion in liquids other than water (ISO 2812-1:2007 [1]); German Version EN ISO 2812-1:2007 or Part 4: Spotting methods (ISO 2812-4:2007 [2]); German Version EN ISO 2812-4:2007.
The PPE blends are characterized by hot water resistance with low water absorption, high impact strength, halogen-free fire protection and low density. This plastic is processed by injection molding or extrusion; depending on the type, the processing temperature is 260–300 °C. The surface can be printed, hot-stamped, painted or metallized.
The performance of fluoroelastomers in aggressive chemicals depends on the nature of the base polymer and the compounding ingredients used for moulding the final products (e.g. O-rings, shaft seals). This performance can vary significantly when end-users purchase polymer-containing rubber goods from different sources.
RTV silicone rubber can be used to cast materials including wax, gypsum, low-melt alloys/metals, and urethane, epoxy, or polyester resins (without using a release agent). A more recent innovation is the ability to 3D print RTV silicones.
This resulted in the commercialization of "Uniroyal TPR" thermoplastic rubber. [5] [6] TPVs are a blend between a thermoplastic matrix and vulcanized rubber - combining the properties of both. A combination of elastomeric properties, including compressibility, tension sets, aging performance, and chemical resistance, characterizes TPVs.
