See whether the contact surface of the profile and seal strip is stained and discoloured, and whether the dust on the surface of the sealing strip is yellow (the oil is easy to absorb dirt), and whether it is contaminated with hands.

3. Some of the cheaper sealing strip fillers will be plentiful, so the surface will not be bright, and those that are cheap will not be bright.

Look at the proportion, how many meters per kilogram. There are a lot of manufacturers, in the use of filler has great checkers, for larger output, a bit (province electricity) using talcum powder, coarse whiting do such things as filler, greatly increased the proportion of sealing products, (our users are more commonly kg is favorable, according to the length of the use of) that virtually increased the cost instead do more harm than good.
