NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying advanced chemical solutions that drive innovation in various industries. In the realm of industrial rubber processing, the selection of appropriate curing agents is fundamental to achieving desired product properties, such as elasticity, tensile strength, and resistance to environmental factors. Among the effective chemical auxiliaries, phenol-formaldehyde resins have carved out a significant niche, and our WS Curing Resin exemplifies the high standards and performance expected in this sector.

Our WS Curing Resin is a specialized thermoplastic p-t-octyl phenol-formaldehyde reactive resin, meticulously developed to serve as a highly efficient curing agent for a variety of elastomers. It is particularly effective 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). This broad compatibility makes it an invaluable component for manufacturers producing a diverse range of rubber goods, from automotive parts to industrial seals.

The application of WS Curing Resin in rubber curing processes requires precise formulation to unlock its full potential. When used alone for curing NR, the inclusion of catalysts such as CR (typically 5-8% of the rubber weight) or stannous chloride (SnCl2, 2-5% of the rubber weight) is essential. For IIR, the reference usage of WS Resin is generally between 7-12% of the rubber. In the case of EPDM, the recommended dosage is approximately 1.5-2% of the rubber weight. These guidelines, provided by NINGBO INNO PHARMCHEM CO.,LTD., ensure that manufacturers can achieve optimal cross-linking, leading to superior mechanical properties in their final rubber products. The physical characteristics of our resin, such as its yellow to brown transparent flaky solid appearance and a softening point of 85-95°C, underscore its quality and suitability for demanding industrial applications.

As a dedicated supplier, NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of quality control throughout the production of our chemical auxiliaries. We understand that consistent product performance is key to our clients' success.
