The neoprene sponge material we use is a closed-end foamed elastomer (honeycomb structure) with extremely low density (light weight), high flexibility and excellent thermal insulation properties. Common types are chloroprene rubber (CR, Neoprene) or styrene butadiene rubber (SBR), as well as a blended product (SCR).
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 & Styrene Butadiene Rubber), "SBR" (Styrene Butadiene Rubber).
Neoprene was invented by DuPont in the United States in the 1930s. It is a synthetic rubber based on the polymerization of petroleum through chloroprene. It was originally used as an oil-resistant substitute for natural rubber. It was used in wetsuits in the 1950s. In the 1960s, Japan YAMAMOTO developed a neoprene based on limestone production, and several manufacturers in Taiwan developed similar products. After entering the 21st century, with the development of green environmental protection and renewable concepts, wetsuits made from natural rubber produced from renewable plants are gradually appearing on the market.
Based on petroleum-produced neoprene, the presence of polycyclic aromatic hydrocarbon compounds (PAHs) and other related harmful substances is inevitable and can only be minimized during the production process. Based on the production of neoprene in limestone, the content of related harmful substances can be kept at a low level due to the raw materials, and products that pass the Oeko-Tex® Standard 100 Class II test can be supplied. Natural plant rubber based on renewable plants (Guayule / Dandelion), we usually call it green rubber.
Usually use "Sheet" or "Piece" as the unit of quotation, in which the cost of neoprene sponge is calculated by thickness, and the cost of fabric and processing is calculated by surface: "Neoprene Sponge Cost" (Thickness, Size and Type) + "Fabric Cost" (Size and Type) + "Processing Cost" (Laminated / Coated / Embossed / Perforated).
Many customers feel that using "Meter" or "Yard" as the quotation unit will get continuous products, and using "Sheet" or "Piece" as the quotation unit will get single piece product, that it is incorrect. The product is continuous or single piece, and has nothing to do with the unit of quotation, only related to the packaging method, "Carton" and "Roll" are continuous products, and "Crate" is a single piece product.
Continuous Product Explain: We use glue to connect the neoprene sponges and then laminate the fabric so that the neoprene fabric looks continuous. But because the neoprene sponge in the middle layer has a connected by glue, can not use continuously, can only use sheet-by-sheet.
"Neoprene Fabric" common packaging methods are "Roll", "Carton" and "Crate". According to the size and thickness of the neoprene fabric, each has its own advantages and disadvantages, and there are also differences in cost. We will adopt the appropriate packaging method according to the actual situation and customer needs.
Continuous Splicing Product Explain: We use glue to connect the neoprene sponges and then laminate the fabric so that the neoprene fabric looks continuous. But because the neoprene sponge in the middle layer has a connected by glue, can not use continuously, can only use sheet-by-sheet.
