Neoprene material explain:
Normative interpretation: "Neoprene" = "CR" ≠ "SCR" ≠ "SBR"
"Neoprene" just refers to the "CR" (Chloroprene Rubber), but now the industry "Neoprene" include "CR" (Chloroprene Rubber), "SCR" (Chloroprene Rubber & Styrene Butadiene Rubber), "SBR" (Styrene Butadiene Rubber).
Normally we call the neoprene rubber sponge (thickness: 22mm / 44mm) as raw material, the product after cutting and laminated (cut thickness, laminated different fabric or coating outside) is called semi finished product (neoprene fabric), the final product is called finished product (the product of neoprene material such as wetsuit, etc). We produce semi-finished product and finished products, semi-finished products (neoprene fabric) have a variety of uses, can be sold alone, the material Department of our factory has been supplying semi manufactured products (neoprene fabric) to manufacturing factories in various countries all over the world.
Neoprene rubber sponge color is black, creamy white, white (only SBR), usually we use black, but if laminated with light color fabric (white, pink, light blue, light green, light yellow etc.), the use of creamy white or white sponge is better, this collocation can better reflect the color and bright of the light color fabric. If use the black sponge will light color fabric dark and distorted. But the cost of creamy white and white sponge is higher than the black sponge. The price of CR grade creamy white sponge is 1.5 times that of the black sponge and is difficult to purchase. Many factories can not provide it. Our factory can provide various grades of creamy white or white sponge.
The main producing areas of the neoprene rubber sponge are Japan, South Korea, Taiwan and China. The SBR and SCR are basically using Chinese sponges, CR sponge some of made in China, some of made in Taiwan, and the less use of the sponges produced from Japan and Korea, The Japan CR sponge is the most expensive. Some customers think there are some differences in performance, But in essence, from a professional factory point of view, as raw materials, the CR sponges of these areas are not very different from the physical characteristics of the similar grades, their main differences are the different production processes (the difference in environmental protection). Moreover, due to the limitation of the laminated fabric (the elongation ratio of the cloth limits the elongation ratio of the sponge), so semi finished products (neoprene fabric) feel no difference in performance. If customers need, our factory produce sponge from all areas can be provided.
The CR sponges produced in Japan are used for double-sided laminated fabric and smooth skin another side laminated fabric (neoprene fabric), which are similar in performance to other products of origin. However, the coating processing material produced in Japan is really better than other producing areas and it is of stable quality and not easy to flake, but it is also expensive. If the customer needs, our factory can provide the coating processing material from Japan, but it will become more expensive for the custom and small batch order, because of the transportation cost. Our factory have not stock semi-finished products (neoprene fabric), are customers to place orders after the production or procurement, the specific reasons for the next paragraph.
There are two uses for coating materials. When used in a wetsuit inside, titanium is usually added. In theory, thermal reflection can be used to enhance the thermal insulation of the wetsuit, but most of the wearers' feedback is very small, if the customer needs it, our factory also provides this product. Used in a wetsuit (Triathlon suit) outside, it can reduce water resistance and improve the performance of athletes in professional competitions. We have provided such products for many national sports teams, but some of the competition rules have been amended to prohibit participants from wearing such products. For ordinary customers, this kind of product is expensive and easy to damage, using smooth skin can also achieve a similar effect.
Because neoprene rubber will age (slow aging, loss of elasticity and strength), so raw materials (neoprene sponge), semi-finished (neoprene fabric), finished (wetsuit) are inadvisable for long time stock. Our Chinese and Taiwan neoprene sponge are usually in stock for less than 3 months, and the Japanese and Korean neoprene sponge stock time is not more than 6 months, the semi finished product (neoprene fabric) and the finished product (wetsuit) we do not stock, they are all produced after customer orders, the semi finished product (neoprene fabric) if the inventory time is more than one year, is not suitable for making the wetsuit, the material and the product which the storage time is too long is not the good choice.
