The base material of PVC edge banding is composed of PVC resin, calcium carbonate powder and various auxiliary materials (stabilizer, DOP oil, ACR, CPE, stearic acid, PE wax, toner, anti-aging agent, etc.). The edge trimming effect of the edge banding is related to the ratio of the base material ingredients.

• Proportion classification: the ratio of PVC resin to calcium carbonate powder

•A. The most basic ratio of 1û1, the trimming performance is whitish, the degree of anti-aging is low, the proportion is large, and the toughness is poor, which is the low-end demand of the market.

• B, 2û1 common ratio, slightly better trimming performance, part of the trimming is white, relatively good aging resistance can reach two to three years, moderate proportion, moderate toughness, is the mainstream custom edge banding in the market Matching.

• C, 3û1 mid-to-high-end ratio, the trimming performance fully meets the mid-to-high-end requirements, basically no whitening, good aging resistance, light specific gravity, and good toughness, it is the first choice for mid-to-high-end custom furniture edge banding in the market .

• D, 4û1 or a higher ratio up to 8û1, these are basically few people choose, and there is no problem in performance. The first-line brand custom furniture companies also choose 4û1, which is at most 5û1. These ratios are very expensive, and the customization factory site Construction is difficult, so sales are relatively small.
