Custom Extruded NR Strip for Absorbing Sealing
NR, natural rubber, is the base material for this extruded NR strip. It performs steadily within a temperature window of -50°C to 80°C. Natural rubber delivers outstanding resilience, which makes it suited for applications needing shock absorption and tight sealing. It handles repeated compression well and bounces back to its original shape after load release, ideal for machinery cushioning, conveyor edge protection and door gap sealing.
Custom extrusion dies are machined to match the profile outlines supplied by buyers. Hardness can be tuned between 30A and 75A. Colour options are limited by pigment compatibility inside the natural rubber compound. The surface texture of the finished strip depends on the finish machined onto the extrusion die.
Cut lengths can be tailored to match assembly workflows at the installation site. Pre-production test samples use the same die and rubber formulation as mass production. Customers can carry out their own fit and rebound tests on these samples to confirm performance before bulk manufacturing kicks off.
The material maintains strong tensile strength and elongation under normal working conditions. It works best in environments free from prolonged oil contact and strong UV exposure. Where the application demands, compound adjustments can enhance tear resistance to stand up to sharp contact or abrasive surfaces.
