In the 1980s, with the popularity of non-slip bathtub mats in Europe, due to the damp and unventilated bathrooms, fungi and algae Gram flora proliferated everywhere, and the bathtub mats slowly began to become moldy and contagious to human bodies. Although rubber materials are mildewed much later than PVC materials, they will eventually become mildewed. In order to completely solve this problem, in 1990s, Claude Company invested a lot of manpower and material resources, constantly explored and experimented. After more than ten years of repeated experiments and demonstrations, in 2006, it finally developed the only mildew-proof antibacterial agent in the world that can be used for rubber bath mats, which can kill most common fungi such as Gram-positive, fungi, algae, etc. It is not only effective for bath mats, but also has bacteriostatic effect on the surface of objects in contact with bath mats. As we all know, almost all antibacterial and mildewproof agents are not resistant to high temperature and cannot be used in high-temperature molded products such as bathtub mats. Therefore, the difficulty of developing this mildew-proof antibacterial agent can be imagined. Nowadays, this patented antibacterial mildew inhibitor is commissioned by Bayer Company in Germany and widely used in Claude's bathtub mats, shower curtains, bath pillows and other products.
In Europe, the longest service life of Claude anti-skid pad can reach about 7 years, and it is not easy to become moldy and discolored, and it is not damaged, but its appearance looks old. In China's hotel industry, since the 1990s, bath mats have gradually become popular, and people begin to understand that the function of bath mats is to avoid the risk of guests slipping for the hotel itself. However, when choosing which brand, material and price of bath mats, most hotels in China still pay the most attention to the procurement cost and ignore the use cost, so it will change slowly over time.
At present, there are about 160 domestic manufacturers of anti-skid mats for bathtubs, with rich varieties and styles, and their market share does not exceed 1 1. Most manufacturers in China produce PVC anti-skid pads, because PVC raw materials are much cheaper than rubber, and the cost of production lines and molds is lower and the processing technology is simpler, so the threshold is very low. PVC bath mats are available in a variety of colors and patterns. The product differences between large and small factories are mainly reflected in the precision of molds, whether the added plasticizer is environmentally friendly, and the level and price of various additives such as stabilizers and antioxidants, which are all reflected in the product price. However, due to the high cost of raw materials and production lines and the complicated process, there are few domestic manufacturers producing rubber bathtub mats, especially the rubber anti-skid mats need to be poured many times, which is close to the tire process, unlike PVC materials.
As we all know, the anti-skid function of the anti-skid pad mainly depends on the suction of the bottom sucker, which can permanently adsorb the ground. Due to the lack of toughness of PVC material, the sucker becomes elastic, and can be firmly adsorbed on the ground by adding plasticizer, but the plasticizer will be continuously lost when it meets warm water, so the inner wall of the sucker is generally made thinner, which can prolong the hardening time of the sucker. Once the sucker begins to harden, the adsorption force will gradually weaken to completely lose. This is also the reason why the functional protection life of PVC bathtub mat is much shorter than that of rubber bathtub mat. In fact, there are also factors in this aspect why automobile tires can only use rubber raw materials.
Similarly, domestic manufacturers of rubber bathtub mats generally use domestic synthetic rubber raw materials and a small amount of natural rubber raw materials, and the content of natural rubber components is almost less than 20%, due to the consideration of raw material cost and formula technology. The natural rubber content of similar products in Europe is not less than 30. This is just like the service life of rubber cups used in toilets and ordinary tires will be much worse. Theoretically, the higher the content of natural rubber, the longer the service life of the material. At present, there are also bath mats made of silicone and TPR in the domestic market. (Generally, the sealing rings of household pressure cookers are silicone, and some spectacle frames are TPR. These materials have good toughness and viscosity, so some anti-skid mat products have no suction cups. Because there is no product of the same material abroad at present, it needs time and practice to test.
In the domestic market, some PVC anti-skid mats have been useless or used for several months, and some mats have yellow spots or black mildew spots, which cannot be removed. This is not dirt, but the reason for the synthetic formula of floor mat raw materials. Adding more additives such as titanium dioxide and plasticizer to PVC can approach the softness of rubber material, but with the passage of time, most additives such as plasticizer will be lost in water from March to June. Mat will become hard and aging, yellow, moldy and cracked, so generally speaking, rubber material is better than PVC material, but the cost of rubber raw material is higher than PVC material.
