Processing methods are described for improving the physical properties of elastomeric materials including elastomeric tubing. The methods include heating tubing in a post-cured step for a specified time and at a specified temperature. The methods also include irradiating the tubing with a desired dose of radiation. Embodiments can include treatment of silicon-based elastomers and/or non-silicon-based elastomers. The improved elastomers can be utilized in pumps.
