Rubber Materials for Precision Components
Compare elastomer families against the medium, temperature, movement and durability requirements of your part. Material selection starts with the application and ends with an agreed compound and validation plan.
01 / Materials
Specify the compound and the service
A polymer family is the starting point for a material discussion. A purchasing specification also needs the compound grade, physical requirements and evaluation conditions. Identify whether you need finished components or compounded material, then describe the part function and the full operating sequence.
02 / Materials
Find the relevant material discussion
Use these routes to prepare questions about specific grades and conditions.
| Candidate family or form | Information to prepare |
|---|---|
| FKM and FFKM | Complete media, temperature, seal geometry and any vacuum or contamination requirements |
| EPDM | Actual fluid or steam conditions, cleaning sequence, environment and assembly |
| HNBR and NBR | Actual oil or mixture, mechanical duty and cold-condition requirements |
| Silicone and LSR | Material form, molding route, flexibility, contact conditions and surface acceptance |
| ACM and AEM | Specified oil, thermal history, mechanical requirements and available grade data |
03 / Materials
Compare the property the component needs
For tear or repeated-load concerns, identify the geometry, notch condition, load path and required test method. For prolonged cold exposure, include hold time, strain state and the motion to evaluate. Keep low-temperature, tensile and assembled-function results with their methods and specimens.
04 / Materials
Clarify other material and environmental references
If the drawing names NR, CR, butyl or another polymer, send the exact grade, duty and requested supply form for review. For recycled-content or degradation information, identify the material, calculation basis or test method and conditions. Evaluate the component’s service requirements alongside that information.
05 / Materials
Define the acceptance and supply basis
Agree the grade, drawing, hardness scale, relevant properties and inspection conditions for the proposed compound. Keep customer-specific requirements with the approval record. For compound supply, identify delivery form and processing conditions; for finished parts, include geometry, quantity and assembly evaluation.
