FAQ

1. How long is the life span of a Taiwan Butyl bladder?
The life span of an unused butyl bladder is about 1 year. However, this depends on the condition of your storage. The life span of the butyl bladder can be extended if you keep them in a suitable place.

2. How do I store the bladders properly to assure the best quality?
All ball bladders must avoid exposure to direct sunlight or hot air as these two factors will harm the bladders and can also lead to some quality problems. If you have any stock of our bladders, please keep them in their original poly-bags and cartons. Finally, the cartons must be covered and stored in a cool, shadowed place. However, we still do not suggest that you keep bladders in stock for longer than one year.

3. There are pinholes on some bladders. Are those bladders defective? Do those pinholes cause air-leakage problems?
Small pinholes occasionally occur on the bladders, and normally will not cause any quality issue. Since a “calender” machine is used to extrude rubber film in our production procedure, air bubbles (called pinholes) are inevitable. At Taiwan Butyl, we make the rubber films with our “double-layer construction” to avoid any air-leakage problem which may be caused by the pinholes. The method is very simple, even if there is a pinhole on the 1st layer of rubber film, it is very rare that another pinhole will occur on the 2nd layer of rubber film at the same location on the bladder.

In order to further make sure all bladders have great quality, all our bladders are inflated for a 24 hours air-leakage inspection. After that, our QC team inspects the appearance of the bladders before packing. All the above efforts are to make sure that only best quality bladders are shipped to our customers.

4. Quick inspection method for air-leakage
At Taiwan butyl, we conduct air-leakage inspection on 100% of our bladders before shipping (24 hours air-leakage inspection). We guarantee our customers with 0.5% defective rate for our products. However, for the very small number of defects that may stay in the production line undetected, we suggest one simple method for you to inspect the bladders air retention, as follows:

One quick method for air-leakage inspection:
When we pack our bladders, we deflate & extract all the air from the bladders for easy packing. Upon receipt of our delivery, just right after the bladders are taken out from the cartons, always check the appearance of the bladders first. All bladders should be completely deflated and there should be no air inside the bladders. If any bladder appears to have air inside, it probably has leakage problem.

5. Avoid using inflating needles longer than 3.3 cm
Avoid using long inflating needles on your production line. We have noticed that long needles tend to pierce the bladder shell during ball production procedure for some of our customers. This issue can be avoided easily by using shorter inflating needles. We recommend that you use inflating needles which are shorter than 3.3 cm.
