Natural Rubber (NR) is a highly versatile elastomer valued for its excellent elasticity, tensile strength, and abrasion resistance. However, to achieve these desirable properties, NR must undergo a carefully controlled curing process. The selection of an effective curing agent is paramount, and NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing high-performance epoxy resin solutions tailored for NR curing, ensuring manufacturers can achieve optimal product performance and durability.

Our WS Curing Resin, a thermoplastic p-t-octyl phenol-formaldehyde reactive resin, is specifically designed to function as a superior curing agent for NR and other elastomers. When integrated into the rubber formulation, this resin facilitates the formation of cross-links, which are essential for transforming the soft, tacky raw rubber into a strong, elastic material. The specific formulation of our resin, characterized by its yellow to brown transparent flaky solid appearance and a softening point of 85-95°C, allows for controlled curing reactions that enhance the mechanical and thermal properties of the final NR product.

The effective use of WS Curing Resin in NR curing typically involves the addition of specific catalysts to initiate and accelerate the cross-linking process. For instance, catalysts like CR (chloroprene rubber), used at approximately 5-8% of the rubber weight, or stannous chloride (SnCl2), at 2-5% of the rubber weight, are often employed to optimize the curing efficiency. The recommended dosage of WS Resin itself for NR is generally between 7-12% of the rubber content, although specific formulations may vary. NINGBO INNO PHARMCHEM CO.,LTD. provides these technical guidelines to assist manufacturers in achieving the desired physical and chemical properties in their NR products.
