Performance characteristics of dense bottom and foamed bottom of PVC plastic floor
Depending on the bottom pad, the plastic floor can be divided into a foamed bottom and a dense bottom. The foamed bottom of the product is called foamed bottom, while the opposite, compacted bottom is unfoamed. PVC plastic flooring is a dense base layer with no foam base. The following Golden Elephant tells you about the performance characteristics of the real bottom and the foam bottom.
1. Most of the products in Europe and the United States use foam bottom, while Korean products like to use dense bottom, and some domestic manufacturers also cater to the market to launch compact products.
2. The bottom of the dense bottom has a high calcium carbonate content of up to 300%, so the product is easily broken in a low temperature environment. The foaming bottom is less likely to be added due to the small amount of calcium carbonate added and the addition of a plasticizer.
3, the rebound of the compact bottom can be very poor, if there is an indentation, it is difficult to rebound to the original.
4. The sound absorption performance of the dense bottom is poor, and the sound absorption performance of the foam bottom is very good.
5, the weight of the dense bottom is heavy, not convenient for transportation and paving.
