Product Introduction

HR-M220B and HR-M221B wet master rubber is a special nano rubber composite material for rubber products and tires and other industries. This product is a pre-dispersed rubber matrix material made of a proper amount of white carbon black and natural latex by wet premixing. The standard ash content is adjustable from 25% to 31%, and it is white or light yellow rubber particles or rubber blocks at room temperature.

Product characteristics

Compared with the traditional natural rubber compound, the main advantages of HR-M220B and HR-M221B wet master rubber are: silica is uniformly dispersed in the rubber matrix, has high filling amount, low filler loss rate and high storage stability, which can significantly improve the comprehensive performance of rubber (high rebound, especially ultra-low heat generation performance),HR-M220B compared with HR-M221B rubber, it has lower hardness and higher rebound performance on the basis of maintaining ultra-low heat generation performance.

Application Scenarios

The products are mainly used in the field of shock-absorbing pads, air springs, engineering rubber and other rubber products and tires with high requirements on product rebound and heat generation.

Packaging and storage

The product HR-M220B and HR-M221B wet master glue are packaged in two layers (the inner bag is made of PE film with melting point less than 115 ℃, and the outer bag is sealed woven bag), or PE film vacuum compression packaging. The net weight of the product is 20±0.1 kg/bag. If you have other special requirements for product packaging, please contact us. Handling procedure: light loading and light unloading, to prevent damage. Storage requirements: Store in dry area. It should be stored separately from easily (combustible) materials and acids, and mixed storage is not allowed. Avoid direct sunlight, waterproof and moisture-proof. If this substance is placed in a flammable solvent, use a suitable ground to avoid an electrical fire. Surface modification of the product caused by calcination or mixing with other additives may alter the toxicological properties. Therefore, we recommend that the product be used within 12 months of production.
