Developing the right compound (material) is a crucial step in the seal and gasket design process.
A compound “recipe” must be developed to enhance or add to an elastomer’s inherent physical and chemical characteristics, and to ensure efficient molding or extruding.
Once a final recipe has been determined, the specific time, temperature and order of ingredient addition are critical in mixing compound batches that repeatedly meet desired specifications.
Since conditions for each recipe vary, it is important to have mixing equipment that is versatile and equipped with features that maintain complete repeatability control from batch to batch.
Lauren’s extensive knowledge of material mixing ensures you receive a reliable supply of high quality seals and gaskets.
Our expertise in material science is advanced through Cooper Standard Industrial and Specialty Group's material expertise, our
in-house silicone mixing facility and our R&D department with full laboratory testing capabilities.
We help you select the appropriate seal material for your application based on the following properties:
• Tensile strength and elongation*
• Hardness range (dense), or compression
deflection requirements (sponge)
• Compression set at room and operating
• UV, ozone, heat, storage requirements
• Color (if color matching is desired
• Speed of recovery from deflection
• Permeability to gases
Chemical Resistance Properties:
• Resistance to acids or caustics
• Hydrocarbon solvents
• Oxygenated solvents
• Flame or temperature extremes
