CR grade Neoprene:<\/strong>\u00a0Soft hand feeling, warm and cold-resistant, with excellent high elasticity. It is mainly used in water sports products and is a primary raw material for high-quality wetsuits, surfing suits, waterproof clothing, professional gloves, and fishing pants.<\/p>

CR Applications:<\/p>

0\u00b0-3\u00b0: surf suit, spearfishing wetsuit, rescue protective suit, diving socks, surfing socks<\/p>

5\u00b0-7\u00b0: wetsuit, fishing pants, dry suit, surfing boots<\/p>

13\u00b0-15\u00b0: technical diving dry suit<\/p>

“CR Neoprene” scientific name “Chloroprene Rubber”, is an elastomer synthetic rubber produced by chloroprene polymerization based on petroleum.<\/p>

Currently, Japan, South Korea, and Taiwan have relatively advanced NEOPRENE production technology, especially Japan, where high-end product materials are sourced. Following Japan, South Korea and Taiwan also play a significant role in manufacturing.<\/p>

Neoprene material sources: YAMAMOTO from Japan, JAKO from South Korea, Nanliang from Taiwan and Neoprene from China.<\/p>

CR elongation is 2-3 times, while SBR elongation is over 1.5 times.<\/p>

Neoprene Hardness is 3\u00b0-15\u00b0, thickness is 1mm \u2013 20mm.<\/p>

\u00a0<\/p>

SCR grade Neoprene:<\/strong>\u00a0CR and SBR are mixed in a specific ratio to create a rubber with good flexibility, making it a versatile material for wetsuits. Depending on the proportion of CR in the blend, there are noticeable differences in elasticity and comfort, and market prices also vary based on CR content.<\/p>

CR Applications:<\/p>

0\u00b0-3\u00b0: diving suit, diving gloves, diving hood<\/p>

7\u00b0-9\u00b0: fishing pants<\/p>

\u00a0<\/p>

SBR grade Neoprene:<\/strong>\u00a0Made from styrene-butadiene rubber (commonly known as SBR, primarily produced domestically), it is suitable for the sports products market and is cost-effective, making it ideal for low-end wetsuits and protective gear.<\/p>

CR Applications:<\/p>

3\u00b0-5\u00b0: recreational wetsuit, diving gloves, diving socks, household products, protective gear<\/p>

7\u00b0-9\u00b0: cup sleeve, computer bags, protective cover<\/p>

12\u00b0-15\u00b0: vulcanized shoes<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
