Industrial moulded parts cover a wide range of functions, from protective pads and bushings to general seals and vibration components. A practical grade review starts with the finished-part duty and current production process.
Define the part before the polymer
Function, environment, hardness and acceptance tests determine whether SBR, NBR or another material family should be evaluated.
Functional Requirements
Explain load, movement, abrasion, sealing, damping or protective functions.
Environment and Media
List temperature, indoor or outdoor exposure, oils, fuels, water and cleaning agents.
Manufacturing Inputs
Provide moulding method, colour, hardness, current grade and any recurring processing concern.
Information to Provide
- Part function and drawing reference
- Target hardness, colour and dimensions
- Media, temperature and weather exposure
- Current formulation or polymer grade
- Trial quantity and regular demand
Evaluation Note
The polymer grade is one input to finished-part performance. A controlled compound and production trial is necessary before substitution or regular supply.
