NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce its cutting-edge WS Curing Resin, a specialized p-t-octyl phenol-formaldehyde reactive resin designed to revolutionize the rubber industry. This high-performance curing agent is crucial for enhancing the durability and functional properties of various elastomers, ensuring top-tier performance in demanding applications.

WS Curing Resin functions as a highly effective cross-linking agent for natural rubber (NR) and several synthetic rubbers (SR) including isobutylene-isoprene rubber (IIR), ethylene propylene diene monomer (EPDM), nitrile butadiene rubber (NBR), and chloroprene rubber (CR). Its primary role is to create a robust network within the rubber matrix, leading to significantly improved heat resistance, enhanced mechanical strength, and superior aging properties. This is particularly vital for components exposed to high temperatures and harsh environmental conditions, where traditional sulfur curing systems may fall short.

Our WS Curing Resin is characterized by its typical appearance as a yellow to brown transparent flaky solid, ensuring ease of handling and consistent quality. It boasts a softening point ranging from 85-95°C, a water content of less than 1.0%, and a methylol content between 8-12%, indicative of its high reactivity and purity. These specifications underscore its reliability and effectiveness in industrial applications. For optimal curing, WS Curing Resin often requires the presence of specific catalysts, such as certain concentrations of chloroprene rubber (CR) or stannous chloride (SnCl2), to achieve the desired cross-linking efficiency.

The application of WS Curing Resin offers numerous benefits to rubber product manufacturers. By utilizing this advanced resin, rubber compounds can achieve superior heat aging resistance, reduced compression set, and improved dynamic fatigue life. These attributes are critical for automotive parts, industrial hoses, seals, and various molded rubber products that demand long-term stability and high performance. The versatility of WS Curing Resin allows for its tailored use, with recommended concentrations varying based on the specific rubber type and desired properties, for instance, 7-12% for IIR and 1.5-2% for EPDM based on rubber content.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that WS Curing Resin is supplied in a convenient and secure packaging format, typically 25kg net weight in kraft bags with an inner PE coating. For maintaining its integrity and efficacy, it is recommended to keep the product stored indoors in a dry and ventilating environment, protected from heat and fire sources, which ensures a storage life of at least one year. As a dedicated manufacturer and supplier of high-quality chemical additives, NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing exceptional products to meet the evolving needs of the global rubber industry.
