As a plastic masterbatch, led carrier tape must have sufficient concentration and conductivity resistance. At this time, the conductivity is generally less than 50 ohms. According to different product requirements, selecting appropriate conductive masterbatch is the key to success.

Generally, the uniform dispersion of conductive masterbatch is the basic requirement for whether the product meets the standard. Since the carriers and requirements of terminal products are different, the carrier and ex factory conductivity value of conductive masterbatch should be confirmed first, so that different conductive masterbatch and addition amount can be used according to different product requirements,

LED carrier tape generally has the following characteristics: 1 The conductivity value of the product is uniform. If three layers of CO extruded sheets are used, the positive and negative conductivity values differ by at most 1 grade; 2. The uniformity of the product is good, and the crystal point per square meter is no more than 3 (generally due to coke); 3. The strength meets the product requirements.
