A Comprehensive Guide to Natural Rubber Blocks in China
China plays a significant role in the global natural rubber market, both as a major consumer and producer. Understanding the nuances of natural rubber blocks, their properties, and the various types available is crucial for anyone involved in this industry. This guide delves into the specifics of natural rubber blocks manufactured in China.
Comprehensive Insights into Natural Rubber Blocks
Natural rubber blocks are versatile materials known for their elasticity, resilience, and resistance to various environmental factors. Their manufacturing process involves vulcanization, transforming liquid latex into a durable, solid form. Plas-fab.com highlights the superior mechanical properties and low compression set of SBR rubber blocks, a common alternative to natural rubber. SBR rubber blocks, while cheaper than natural rubber, offer excellent tear and wear resistance, making them suitable for a wide range of applications.
The choice between natural rubber and its synthetic counterparts often depends on the specific application requirements. Natural rubber, sourced and traded by companies like those found on www.natural-rubber.com, is prized for its superior elasticity and resilience, but can be more expensive. Synthetic options like SBR, NBR, CR, EPDM, and FKM, readily available from manufacturers such as www.sbrrubbersheet.com, offer varying degrees of resistance to heat, oil, chemicals, and abrasion. The selection should align with the specific needs of the intended use.
Technical Features of Natural Rubber Blocks
The following table compares the key technical features of different natural rubber block compositions:
| Feature | Natural Rubber (NR) | SBR Rubber | NBR Rubber | EPDM Rubber | FKM Rubber (Viton) |
|---|---|---|---|---|---|
| Elasticity | High | Moderate | Moderate | Moderate | Low |
| Tensile Strength | High | Moderate to High | Moderate to High | Moderate | High |
| Abrasion Resistance | Moderate to High | High | High | High | Very High |
| Heat Resistance | Moderate | Moderate to High | Moderate to High | High | Very High |
| Oil Resistance | Low | Moderate | High | High | Very High |
| Chemical Resistance | Varies | Varies | Varies | High | Very High |
Different Types of Natural Rubber Blocks
The available types of natural rubber blocks often depend on the manufacturer’s specialization. The following table illustrates some common types and their characteristics:
| Type of Rubber Block | Material | Key Characteristics | Typical Applications |
|---|---|---|---|
