Inquiry
A plant manager called last week, frustrated with calcium carbonate scaling heat transfer efficiency by 12% in their condenser tubes—we've sent samples of the carborundum version before, and it usually does the trick for that kind of hard deposit.
RY series runs form 7mm to 38mm in diameter, with hardness ranging 30 to 60 Shore A, and tensile strength hits at least 16 MPa with elongation over 450%, so they'll flex through tight bends without tearing.
Water absorption is excellent, which is what makes these balls swell slightly as they travel, scrubbing the full inner surface—but they're not suited for systems with very high flow rates above 3 m/s or so, because teh silicone rubber can deform too much under that shear.
Actually, we typically stock red and black in the most common sizes, but yellow and green need a 10-30 day lead time for custom batches.
Minimum order is 500 pieces, which is pretty standard for this kind of part, and our company can provide samples (usually 2-4 weeks) if you need to test fit before committing.
Anyway, most buyers go with the 25mm diameter for standerd condenser tubes, and the carborundum grit embedded in the suface handles calcium deposits better than plain sponge balls.
MOQ is 500 pieces per size and material. We do offer samples — just cover the shipping cost and we'll send a few pieces so you can test fit and performance before committing to a full order.
Standard lead time is 10 to 30 days, depending on the quantity and whether you need a custom color or hardness. We'll give you a firm timeline once we confirm the specs.
Yes, our RY Series is ISO 9001 certified for quality, and we comply with RoHS and REACH regulations, so they're safe for use in sensitive industrial environments.
We can adjust hardness within that 30-60 Shore A range to match your tube material. Anything outside that would need a custom formulation — just let us know your requirement and we'll check feasibility.
Keep them in a cool, dry place away from direct sunlight and ozone sources. Proper storage ensures the rubber stays elastic and the carborundum coating remains effective over time.
