Chemical compatibility measures how suitable a particular elastomer is for its function and durability for your application. Chemical Resistance is measured by:
The process through which a chemical agent invades the material at a molecular level
The flow of chemical agents through porous materials, closures or seams in the material used.
Damaging changes in the material's physical properties on exposure to chemical agents.
Our online guide provides a ready reckoner with basic information about elastomers and their properties to help you select the one suitable for your application.
What our chemical resistance guide offers you
The Chemical Resistance Guide is a quick reference tool with Performance information and Volume Change Tables. These tables reveal the suitability of elastomers with pointers to help you choose the appropriate material for use in different chemical-based environments.
Performance information such as chemical resistance of several types of elastomers are tested at room temperature conditions, as many conditions can affect material choices. Careful consideration must be given to temperature, pressure, & concentrations of the media the rubber is in contact with.
Volume Change here in the table is only a reference indicator to show suitability of elastomers with different media in contact with. The chemical attack on the polymer largely affects several other physical properties. Increase in operating temperatures when product in use also accelerates the speed at which the chemical deterioration takes place, seek support from our team for clarification on materials acceptability for your end application.
Factors to Consider
Several factors must be considered when using materials in service being,
- Temperature of service
- Conditions of service
- Grade of polymer
- Compound designed
Guidance to Choose
Intended to provide guidance in choosing the suitable elastomer/s under different chemical-based environments, the suggested ratings are from the laboratory tests conducted at room temperature (it does not determine the end user performance).
