You're looking at a 20-50 MPa tensile strength range and 300-600% elongation at break, which basically means these polyurethane seals can take repeated mechanical abuse without failing, and we've seen them outlast rubber alternatives by 3x in high-impact conveyor application.
The hardness range spans 50A to 95A, so you'll pick teh specific durometer for your load conditions — softer for sealing on moving parts, harder for static compression on flanges — and the -30°C to +80°C window covers most mining and material handling environments without brittleness at the low end.
What makes these reliable is the abrasion resistance combined with oil resistance that's good to excellent across most petroleum-based lubricants and hydraulic fluids, and every batch ships with a COA form our ISO 9001 line (usually 2-4 weeks for full documentation if you need it expedited).
Ordering is straightforward: we need your dimensional drawing or existing part for size and shape matching, then we'll confirm which hardness and color works best — black is the default, but custom colors are available with longer lead times of 20 days or so for bulk runs.
The MOQ is 100 pieces for production orders, and samples are available in 5-7 days so you can test fitment before committing, though we usually have stock on common sizes like 50A black wipers and 80A scraper seals.
Anyway, most buyers go with the 70A-90A range for conveyor skirting and belt scrapers, but if you're sealing hydraulic cylinders in a washdown enviroment, the 50A with custom color coding helps with maintenance identification — just confirm the oil type because some aromatic solvents can swell material.
MOQ is 100 pieces, and lead time runs 15-20 days for bulk orders. Custom hardness within 50A-95A is no problem—just specify when you order.
Yes, we include ISO 9001 certification docs and can supply material test reports on request. Just ask when confirming the order.
Absolutely. Samples are available and take 5-7 days to ship. We can match your custom color for the sample, but there might be a small setup fee.
We pack them in sealed poly bags inside cartons to keep them clean. Store in a cool, dry place away from direct sunlight—between 10°C and 30°C works best for long shelf life.
Top tensile strength is 50 MPa, paired with elongation at break around 300%. Higher hardness usually boosts tensile but lowers elongation—we can tweak the formulation to balance both for your application.
