1. SBR Fabric:

◦ Definition: 15% CR (chloroprene rubber) + 85% SBR (styrene-butadiene rubber).

◦ Performance Logic: SBR is low-cost and soft, but has poor elasticity, weather resistance, and aging resistance. The high proportion of SBR results in weak rebound, easy deformation, and rapid loss of warmth retention. Its closed-cell structure makes it the weakest of the four.

2. SCR Fabric:

◦ Definition: 30% CR + 70% SBR.

◦ Performance Logic: The increased CR proportion and the crucial “compression” process compensate for some of the shortcomings of SBR, creating a high-density, high-rigidity, and extremely wear-resistant structure. Its “elasticity” feels like dense rigidity, rather than soft extensibility.

3. CR Fabric:

◦ Definition: 100% CR.

◦ Performance Logic: Pure neoprene offers the best balance of performance—good natural elasticity, excellent compression resistance, stable insulation, and durability. It is the benchmark for performance.

4. Yamamoto Fabric:

◦ Definition: 100% high purity/patented CR formula.

◦ Performance Logic: Building upon the top-tier 100% CR, a proprietary foaming technology creates a closed-cell structure with smaller, more uniform bubbles and a stronger film, achieving ultimate softness, high elasticity, and lightweight.

Ultimate Purchase Recommendation:

• Choose performance based on composition: Within your budget, choose fabrics with a higher CR (neoprene) ratio. From SBR -> SCR -> CR -> Yamamoto, this is a clear path to simultaneously improve cost and core performance.

• In short: Your data is the gold standard—CR content determines the “ceiling” and “floor” of fabric performance. For serious divers, choosing between CR and Yamamoto is a choice between “good” and “better”; while considering SBR or SCR means accepting their definite performance shortcomings (durability or comfort) to meet specific needs (lowest cost or highest abrasion resistance).
